Really enjoyed this - perfect with a Saturday morning mug of coffee. Im slightly embarrassed to say (although only slightly) I've got 5 gshocks now, mostly picked up used from ebay, and have had a couple open to change batteries. The debris that fell out of one of them was enough to plant a small plant, but under the real caseback it was mint - amazing really. Thanks.
This gentleman made a charming and humble little video, demonstrating skills most of us will never have, to entertain and educate. And yet receives negative comments and even personal put-downs from viewers who seem to take themselves too seriously. Enjoyed the video. Encouragement to continue.
I'm a watch and clockmaker. I've owned my G-Shock since 1989. Only had to replace the battery once. It's now on year 9 of battery number 2. I even done a video of me throwing it at a pebble dashed wall and 50ft in the air to prove how tough it is. It'll outlast me.
It's great to see a proper watchmaker working on another form of proper watch that millions of people own, digital, without being stuck up about it. Great video.
What's crazy is I've been playing around with the inside of G-Shocks since I was a kid. Not to this extent, sure, but just to open, clean, change batteries, reseal, fit new springs, fix poor button connectivity etc. I would struggle with mechanicals I'm sure of it., I always used to outsource those repairs. The work done here is pretty intense for my abilities! P.S. I've actually replaced those pernickety springs with trimmed springs from spring-loaded pins and the watch beeps have been fine!
So you have watched another channel? Because when opening the watch there was a lot of sand. Instead of cleaning it first, he opened the case, so sand is in the watch at that point. After that, he turned the movement upside down with sand on the case. I would not let hem near any of my watches, ever!
Just a tip for most analog-digital G-Shocks, press and hold the set button (top-left) for 5 seconds until it enters the hand adjust option. This allows you to “zero” the analog hands so they correspond with the correct digital time. Press the mode button (Bottom-left) to switch between the main hands and sub dial. Use the right buttons to move the hands position to get them back to zero. Press the adjust button (top-left) to exit this mode. This should be done every time there is a battery change, or if for whatever reason the hands don’t match.
Hi Neal... Thanks for this. I actually misaligned the hands a little ( in relation to one another) so I went back in and sorted that out. Then i read the manual and used the facility you describe to sync the hands with the digital read out. It worked very well. Good tip. Thanks so much l. Richard
Most higher end Casios have a "touch movement". This is Casio-speak for actuators on the hand motors that let the watch know their exact location. This is why they need to be adjusted after a battery change. Also the buttons on G-shocks have dual gaskets instead of the more normal single gaskets, which makes water ingress unlikely. This also means the buttons are large.
Well done, Richard! In this episode, you have satisfied my undying curiosity of G-Shock watches. It has always fascinated me on the inner workings of these iconic watches. Once the watch was reassembled, and I witnessed the functions as the mode control was manipulated, I now realize the necessity for two batteries. This was quite enjoyable, and educational at once. Thank you for posting! Cheers!
A couple of months back I opened and stripped a G-Shock completely. It is really interesting to see how small the actual movements are,on the these modules, each smaller than the battery, and how tiny small the motors are. They are smaller than the smallest screw on the movement.
How nice you live in Pembroke Dock! I lived there as a boy in Gwyther Street, and my Gran and Gramps lived in North Street. My Gramps was the shipwright who built the Cleddau King & Queen Neyland ferries, and my Dad flew Sunderland bombers from the dockyards in WWII. Love Pembrokeshire.
Hi Eifion... That's amazing! Your family are truly Pembroke Dock with both the Shipwright and Sunderland contributions! Brilliant! Maybe you were here in The Dock's golden era... It's a little run down in places at the moment but I do like living here... Always something going on! So nice to hear about your family's connection and contribution to The Dock! Richard
12:24 does anyone know if these little springs are made out of gold or contain any? I wanted to buy one but for personal reasons I can't wear anything containing gold
Brilliant mate, love my G's. They're in rotation with much more expensive pieces but I get just as much if not a little bit more fun wearing them. Appreciate seeing the guts of one, cheers my friend 👍🏼
I enjoyed this video. As someone with a host of the usual Swiss Rolex, Breitling, IWC watches, since retiring I now have four G-Shock watches. The MTG-B1000, GWG1000 Mudmaster, GWN1000 Gulfmaster & GPR1000 GPS Rangeman. They make great daily beaters IMO and I love not having to worry about damaging something expensive.
Hi Ray ... I think Casio have done something very clever with G-SHOCK because these watches seem to transcend the whole of the rest of the watch market and have a following amongst luxury watch enthusiasts and folks that are really just interested in G-SHOCK. Thanks for for the feedback which corroborates this view! Richard
Thank you for the follow up video to your purchase of the Carbon Core. I used to have a large collection of battery powered G-Shocks but always dreaded the battery change. I now only own the solar versions because i could never test water resistance after opening the back. G-shocks are a wonderful range of watches and i wouldn't want to wear anything else to work.
Have a look at the Chinese pressure testers. They are about a tenth of the price of the Swiss made ones and do precisely the same job of testing to 3 atmospheres (the swiss standard). That's all most testing is done to, unless it's for industrial purposes (like actual deep dive equipment, which is extremely rare). It's a pretty safe test. The watch sits on hanger in the tank above the 300ml of water which you put in there. You then pressurise the cylinder to 3 atmospheres (most dials go to 6 max but there's really no need). After about a minute you then lower the watch into the water and slowly let the air out. A leak is indicated by a significant stream of air bubbles coming from the watch. A little coming out around the bezel is normal.
@@Chris_the_Muso Hi Chris, I never thought if actually being able to afford pressure test equipment! What site/s can I get one from and roughly how much do they go for?
@@ianjamieson3985 I got mine from Ebay, AU$270 including shipping, and I've been using it about a year so far. It's one of those things you use occasionally, but no other tool can replace it. I charge $20 additional for pressure testing (clients choice) so it has probably paid for itself a few times. I think all the seals and 0-rings are standard parts so it is probably serviceable if it ever needs it. At that price it's easy to justify the purchase.
Nicely done! I came upon your video and since I have the same watch in all black I was excited to watch. I would have never thought there would be any debris inside. I thoroughly enjoyed watching this. Thanks for sharing it. 👍🏻
This is a very interesting video Richard. Although I don't own a analogue/digital G-Shock watch I do own two 5610 radio controlled/solar powered G-Shocks. I have always wanted to see the inside workings of them though. One day I might get an analogue G-Shock but I wouldn't want to do what you did in case it never worked again. Thanks again you are amazing 👏
Nice show sir. G-Shocks are magnificent monsters. Maybe not for everyone due to size and bold - sometimes odd - styles, but no one can deny their capabilities at this point in quartz history.
A good story sometimes ends where it started, glad to see the G shock made it back to the beach. More G shock content of this caliber on RUclips is needed
Terrific!! Epic tear down, service and rebuild. I have this model of G-Shock in black, which I have mildly modded with a khaki bezel and Suunto strap which is much softer and more comfortable than the standard one. Anyway, you have inspired me to dive deeper into the watch and apply white lume to the hour batons, this should lift the watch visually and improve it's already excellent usability. Looking forward to your next project, thanks for the detailed video for this G-Shock tear-down.
Richard, when I first saw you doing this I was like "Why is he servicing a g-shock?" Then i saw the crud that had worked its way inside. So while a digital doesn't need to be serviced in the same way a mechanical watch does, it still needs to be cleaned occasionally. Bang on video, mate!
Hi JToddHubbard7 .... I did 'go a little further' a little further than was strictly necessary to remove the crud; but it was interesting right? An occassional clean as you say is a good thing with all watches I guess. Thanks for the feedback. Richard
Wow !! This video is so interesting, It could be a reference to repair G-Shock watch ! So nice job Mr. Richard and of course thank for sharing ! Happy to see you on the channel again !! ✨👌
Such a calm and methodical demeanor…perfect fit for your vocation!! You actually made me believe I could do this! (Which I could, but I lack the patience and confidence). Subscribed!
What an interesting video. Thank you! Nice to see craftsmanship in any form. In case it is useful to know, the central protruding spring which extends beyond the insulator on the back of the circuit board is to connect the watch electronics to the piezoelectric speaker for the alarm noise. This speaker is visibly mounted on the inside of the metal watch back. I don’t think the spring has any other purpose. Putting the metal back in place may have further compressed the other non soldered electronic connections or the zebra connector against their contacts to make the electronics fully functional. It was unlikely to be related to the spring I think.
33:23 actually you can do the disc adjustment with buttons combination (I forgot which buttons, but it's in the manual) Because the disc will slightly misaligned sometime if you drop or bump the watch (it's outdoor watch, so that to be expected) It's good that Casio provide a solution to aligned the disc (and the hands too) without having the user to open the case, they know we will abuse the G-Shock
Hi Fajar! Good point sir! And yes I used this facility when I went back into the watch to correct the hand misalignment that was apparent when I had finished shooting the footage. Thank you for taking a moment to highlight this to folks reading the comments as it is a useful point. Richard
That was an enjoyable journey into the unknown. The fact that it was your first time entering the G-Shock allowed us to follow your method and thinking and also discover as you did, in real time together. Thanks 👍
Hi Patrick ... Yes it was a bit of a 'journey into uncharted (by me) territory'. I thought it would be fun and folks seem to like it so very happy with that. Richard
I love the look of your new Major "in the white" stainless steel! Maybe you could show us a little of putting these (or the next batch) together in a video.
Very interesting, I have only owned square Casios and never bothered to learn what the innards looked like on the other models, it having stepper motors really blew my mind. Very nice content 👍 If it's any consolation for forgetting the hands, I tried cleaning my old DW-2500 once and finished with 3 missing E-rings and 1 missing washer that held the buttons in the case😂
Hi Tarou Yamada ... Thank you so much for taking a moment to say you appreciated this video. Your comment about the work on the DW-2500 made me chuckle! Thanks again. Richard
Appreciate the care and precision you bring to this watch. A guy on one of the G-Shock channels attacks his watches with a battery operated screwdriver.
Interesting. Straightforward and really instructional guide for electronic watches. I can now do my G shock. The furthest I got into it, replace the cell batteries. Thanks
Richard, I must admit I felt more anxiety watching you work with this module than I do when I normally watch you with mechanical watches. "Accidentally too deep" is a super scary term!
Richard your macro photography is really good! Thanks for the video, I own a number of G Shock watches and battery changes are about my limit of being comfortable taking one apart. Cheers from Nova Scotia…MikeR.
Nice video from a pro perspective. I did the same with a Timex Ironman 8 Lap from the early 90’s (?) and it really reminded me why I truly loved that watch. Great watch for working out and outdoor activities. I wouldn’t sell it for anything.
Je vous remercie pour cette vidéo très instructive ! On est loin du charme et de l' élégance de l'horlogerie " classique ", avec son étalage de l'ingéniosité humaine et je n'aurais pas été plus avant dans l'étude de ce genre de montre, sans votre travail !
As a newcomer to Casio G-SHOCK really enjoyed the video . I have an omega planet ocean quantum of solace watch which was never of my wrist from 2007 until he stopped in March this year . It was sent of to omega for a service and still not back 4 months later I needed a watch so got a Casio mud master which is an amazing watch but then started collecting G-SHOCK up to 5 now and stopped chasing omega up to find out when it will be sent back might even sell him as I have my eye on a few more and my girlfriend in on the act now wearing babyG which gets for more comments than my omega ever did . Thanks for the video will start watching all videos now a subscriber many thanks phil in Blackpool
Lol im with you have a couple of omegas too, same on the plannet ocean. Started off with basic mud master, built up to maharishi yellow strap version, red strap version, earth and acionn, mananged to ge t a frogman icerc,, love it for the colours,, love them, deffo collectable,, keep your collection, going
When I see that those supposedly 10 seconds per year ETA PreciDrive (thermocompensated quartz) movements have jewels (3 to 8, depending on the model), I’m always of two minds. Part of me is saying “quality!” and “it can be serviced!” and another part of me is saying, “I paid under US$200 for this Certina watch new, though the list price is far more, and service would consist of replacing the movement with a new one that’s $65 retail, so wouldn’t I be better off with a no-jewels movement like the one in that solar radio-sync Citizen watch I wore daily for ten years and still occasionally wear?” If a watch is quartz-based and too cheap to be serviced (barring sentimental reasons such as being Dad’s), are jewels just points of failure? Maybe? I’m stunned that the G-Shock case is so leaky! It looks as if it’s impervious but apparently it’s only as good as it needs to be… or rather, the delicate innards are safe behind that gasket, but the outer portions of the case are free to accumulate water and dirt in small doses.
Funny how you first talk this technological marwel down, and then give it a high score! It IS a marwel! Some of this video was painful to watch, but you made everything good in the end! Thanks for the video!!
Probably a good idea when you noticed the sand and dirt under the yellow case back would have been to stop and brush it off/ blow it off before opening the watertight seal. Some analogue g shocks also have the ability to set home points (with a series of button presses) for the hands and wheels, most likely in the instructions.
Wow so much patience and Skill. There’s something about you folks working on Watches, all those tiny Springs were making me nervous lol. Can you open up and clean a Gravitymaster GPW-2000. I liked how you gave the Coordinates of the beach at the end lol.
Lot of fun watching this. I've changed the batteries in my G a couple of times, but never went that deep into it. One thing, at the end when you are trying to get the mode wheels and hands properly linked... in the Casio manuals for the specific module (available for download), there is a step by step procedure to get everything properly aligned without physically working with the hands. It's different for every module, but anyone can resync without even opening the watch.
I used to scuba dive. After you've been to the beach it's extremely important to wash everything made of metal in fresh water to remove all traces of salt. In this case where it has a plastic over shield, leave it soak for half an hour with occasional agitation. I would have been tempted to use a little rust converter on the rust stains. About 5% phosphoric acid for about half an hour. You can buy 85% food grade phosphoric acid and dilute 1:16 with a little distilled water. It does tend to leave bare steel with a blue/black patina (iron phosphate) but doesn't touch coatings (your mileage may vary). The bare steel can then be retouched with a little enamel paint or recoated to prevent further corrosion.
Hi Chris .... Yes my post salt water drills could definietely use a little improvement. Thanks for the tips on anti-corrosion, useful for these to be in the comments for everyone to read so thanks for that! Richard
Hi Greg... Seiko Twin quartz is such a discerning niche sir! These are really excellent watches... be prepared for tiny pivots in the low torque power train. Enjoy! Richard
@@richardperrettwatchmaker thanks, Richard. I've spoken with two watchmakers about having my 9943-8000 serviced. One told me it would be a waste of time and money, the other said anything with a gear train should be cleaned and oiled after almost 45 years. Have to say I'm in agreement with the latter.
Very interesting. I thought for a moment that you had forgotten the markers. I have to say that, every time I see your Major watch, I can't help thinking of Faulty Towers... "Faulty, is that you?" "Yes, Major."
Thanks for this video! Absent of your watchmaking skills, a dirty and water-damaged G-shock would be unceremoniously introduced to the bin. I thank you for granting new life to at least one. But if you're going to clean and rehab one of the watch world's more economical brands, that "1965 Seiko-Matic with the dodgy bracelet" is absolutely entitled to some love!
Fantastic to see the level of miniaturization that casio achieved on electromechanical parts. Just some comments, The Spring on back is to make contact with the piezoelectric speaker attached on inner face of back metal plate. All g-shocks have same approach to electric ans mechanic connect the speaker. After the change batteries it is also necessary to enter on hands alignment procedure as described in owner's manual.
"My G-Shock is going to smell so good ". 😂😂 Reminds me of your un- boxing of the Invictor pro-diver when you "sniffed" the box . Great video as always Richard. By chance I was in Pembrokeshire last weekend visiting MHCG & one of the coastguards on duty was wearing the exact same watch ! I'm now looking to ad this one to my growing collection of Casio watches, my first being the vintage classic A203 Blue Thunder received as a present in 1980 which is still going strong ! Looking forward to your next video.
Hi Simon ... Comforting to know that the folks at Milford Haven Coast Guard are discerning about their watches! The Coast Guard and RNLI are important folks and always pretty busy down here. 'Gingers' is the place a nice coffee and cake in Milford ... I find myself in there quite a lot! Richard
I bought my first G Shock GA-2000 after I saw your first video about the model. It’s a great watch, and not long after buying it, I saw another color way-my first one is green with a negative digital display, and as I said, it’s great, but when I saw the same model in white with a positive display, I couldn’t resist it, so I bought it as well. Both my GA-2000’s have non-skeletonized hands, because I think they’re more legible..to sum up, the GA-2000 is a great design by. Casio, and your first G Shock video inspired me to buy it..I’m happy with my purchases.
G-Shocks are my guilty pleasures! Love the things. Excellent video and really enjoy your Channel. If you want to see what Casio can really do have a look at the Oceanus range! 👍
One thing you missed, is that the pushers come out too. Behind the button they have a cavity where their return sprint lives. This place collects a lot of gunk too and here it'll affect the feel of the pushers too. They also have tiny O-rings that can benefit from a bit of grease. Having that centre spring electrically floating isn't a problem to these modules, it only handles the beeps. What was probably happening is that the light pusher pushed the module out a bit, preventing it from actuating. Usually these watches have a reset contact point, which you should connect to ground (the metal module frame) for a second after a battery change. You can probably realign the wheels in software as the stepper motors have no way of keeping track of position and can drift when turning while receiving shocks. It was cool seeing how incredibly well-built these fancier G-Shocks are. I've dug DEEP into my GBX-100 in my modding adventures with it and it's nowhere near as well put together. Same with the few cheaper non G-Shock Casio's I've taken apart, but all is relative as they stand far above the other cheap digital brands.
Thank you Richard for another watch anatomy class. Always enjoy the quality of your shots, your steadfast hands and clear narration in every video. So got me curious if you film, work on the watch, and narrate simultaneously. Or you just focus on filming and working on the watch, and dub your voice during editing? Anyhow really enjoy all facets of your videos and hope you will find time to produce more great comments and your Major watches.
I have the green one. Terrible to read and to operate, but very cool. I will remember this video when I need to repair it, although I don't expect that I will ever need it ;). Nice video.
Hi ORB wheels and watches ... Learn as much as possible through reading and RUclips. Practice as much as possible on inexpenisve junk watches (ebay is a good source for old broken stuff). Set up a website (Wordpress is easy to do) and show your work on social media. Soon you will be taking on non-precious jobs for family and friends and in a few years you will get you first paid work for sure. Oh ... and don't work too hard; it's really important to enjoy your work! Hope this is helpful and good luck with it! Richard
@@richardperrettwatchmaker Thanks, I’ve already got speaking to a channel called CRM Jewellers and the video we made together should be released on Wednesday.
Fascinating video. I am amazed with the quality of a simple G shock watch. It would be interesting to take apart one of the more expensive Master of G models like the Frogman GWF-A1000 or a really high end Oceanus model wihere the fit and finish of the case is similar to Grand Seiko watches.
Hi Culture Vulture... The way the module rests inside the Carbon Core naturally provides a measure of isolation from shock as the module can shift around and then settle. This combined with the wider, less brittle pivots in the stepper motors stacks up to a pretty resilient package I guess. Hope this explains. Richard
hello from a wet and windy Swansea on shore for a change ( and not enjoying it ) great to see some else from South Wales has taken to this hobby Im still picking up watches from free sources to play with
I worked in the security industry and wore a G-Shock all that period. It was great as it took the knocks of hard everyday outdoor wear. Any other watch would have shown the scars of commensurate environmentalist age but not so the G-Shock. Most military and p0lice wear them as well, because G-Shock takes the heavy and often outrageous nocks the outdoor activity.
First time here and glad I found it. Great content.. question? I am rowing the Atlantic from La Gomera to Tenerife. Approx 3000NM as the crow flies.. approx 40-50 days at sea. What watch would you recommend that could cope with that task? Robust enough for the daily dings. Good time keeping. Fit for task in hot weather, obvious wet conditions and features that would suit a crossing?? Also price point would be a factor.
Hi there! Well spotted... I went back in and sorted that because it was bugging me. Also used the facility to sync the hands with the digital read out. Thanks for the feedback. Richard
I own a GW6900 which is solar and atomic. I run and swim in the ocean with it all the time. I was a little concerned to see how much water and sand ingress you got in your G, given that I don’t intend to open mine up and change a battery.

Thanks again you are amazing 👏
Nice show sir. G-Shocks are magnificent monsters. Maybe not for everyone due to size and bold - sometimes odd - styles, but no one can deny their capabilities at this point in quartz history.
Great video, and I too have always wanted to see what's actually in the back of these pieces. Brilliant Mate!
A good story sometimes ends where it started, glad to see the G shock made it back to the beach. More G shock content of this caliber on RUclips is needed
Terrific!! Epic tear down, service and rebuild. I have this model of G-Shock in black, which I have mildly modded with a khaki bezel and Suunto strap which is much softer and more comfortable than the standard one.
Anyway, you have inspired me to dive deeper into the watch and apply white lume to the hour batons, this should lift the watch visually and improve it's already excellent usability. Looking forward to your next project, thanks for the detailed video for this G-Shock tear-down.
Thanks for the feedback Larx and very pleased this has inspired you to dive deeper yourself! Richard
Richard, when I first saw you doing this I was like "Why is he servicing a g-shock?"
Then i saw the crud that had worked its way inside.
So while a digital doesn't need to be serviced in the same way a mechanical watch does, it still needs to be cleaned occasionally. Bang on video, mate!
Hi JToddHubbard7 .... I did 'go a little further' a little further than was strictly necessary to remove the crud; but it was interesting right? An occassional clean as you say is a good thing with all watches I guess. Thanks for the feedback. Richard
Wow !! This video is so interesting, It could be a reference to repair G-Shock watch ! So nice job Mr. Richard and of course thank for sharing ! Happy to see you on the channel again !! ✨👌
Thanks Alain ... It's so nice to have a new video out. Very Happy that you enjoyed this one! Richard
Such a calm and methodical demeanor…perfect fit for your vocation!! You actually made me believe I could do this! (Which I could, but I lack the patience and confidence). Subscribed!
Great video, Richard! This looked so much more complex than your usual mechanical servicing!
Hi Neel .... Yes, I was a little out of my comfort zone on this one! Thanks for the feedback. Much appreciated. Richard
I’m no fan of G-Shocks but that black and yellow one of yours looks pretty badass.
Not your usual watchmaking vid, but bloody entertaining none the less. Thanks Richard.
Thanks Mark .... Yes I went for something a bit different this time to keep things fresh! Hope all good with you! Richard
@@richardperrettwatchmaker All good and hope the same for you.
What an interesting video. Thank you! Nice to see craftsmanship in any form. In case it is useful to know, the central protruding spring which extends beyond the insulator on the back of the circuit board is to connect the watch electronics to the piezoelectric speaker for the alarm noise. This speaker is visibly mounted on the inside of the metal watch back. I don’t think the spring has any other purpose. Putting the metal back in place may have further compressed the other non soldered electronic connections or the zebra connector against their contacts to make the electronics fully functional. It was unlikely to be related to the spring I think.
33:23 actually you can do the disc adjustment with buttons combination (I forgot which buttons, but it's in the manual)
Because the disc will slightly misaligned sometime if you drop or bump the watch (it's outdoor watch, so that to be expected)
It's good that Casio provide a solution to aligned the disc (and the hands too) without having the user to open the case, they know we will abuse the G-Shock
Hi Fajar! Good point sir! And yes I used this facility when I went back into the watch to correct the hand misalignment that was apparent when I had finished shooting the footage. Thank you for taking a moment to highlight this to folks reading the comments as it is a useful point. Richard
I am a G-shock fan and find this video very interesting! Very good start on the saturday!
I will check out your own watchbrand.
That was an enjoyable journey into the unknown. The fact that it was your first time entering the G-Shock allowed us to follow your method and thinking and also discover as you did, in real time together.
Thanks 👍
Hi Patrick ... Yes it was a bit of a 'journey into uncharted (by me) territory'. I thought it would be fun and folks seem to like it so very happy with that. Richard
I love the look of your new Major "in the white" stainless steel! Maybe you could show us a little of putting these (or the next batch) together in a video.
Very interesting, I have only owned square Casios and never bothered to learn what the innards looked like on the other models, it having stepper motors really blew my mind. Very nice content 👍
If it's any consolation for forgetting the hands, I tried cleaning my old DW-2500 once and finished with 3 missing E-rings and 1 missing washer that held the buttons in the case😂
Hi Tarou Yamada ... Thank you so much for taking a moment to say you appreciated this video. Your comment about the work on the DW-2500 made me chuckle! Thanks again. Richard
Probably one of the only serviced G-Shocks ever. Thanks for sharing 👍
I happen to know that passionfruit-pomegranate dish soap is the case cleaner specified by the Casio factory. Well done. 😉
Appreciate the care and precision you bring to this watch. A guy on one of the G-Shock channels attacks his watches with a battery operated screwdriver.
Would one clean the backplate (Rust and sand) before opening it up? 🤷♀️
Hi CatLady .... I think maybe one would. Well observed! Richard
Had to smile at your description of "getting agricultural," coming from a former tank maintainer!
Interesting. Straightforward and really instructional guide for electronic watches. I can now do my G shock. The furthest I got into it, replace the cell batteries. Thanks
Of course a watchmaker in the UK would have a g shock with a world time complication....! Nicely done!
Richard, I must admit I felt more anxiety watching you work with this module than I do when I normally watch you with mechanical watches. "Accidentally too deep" is a super scary term!
Hi Clay! Great to hear from you! Yes ... I was not really in my comfort zone. All's well that ends well though I guess! Richard
Richard your macro photography is really good! Thanks for the video, I own a number of G Shock watches and battery changes are about my limit of being comfortable taking one apart. Cheers from Nova Scotia…MikeR.
Well done Richard great video, I like the look of the new sea wolf , still live mine my daily wearer , see you next time 👍🏻
Hi Paul, Good to hear from you and very pleased your own Sea Wolf is getting a lot of wear. This video was fun to make! Richard
I can't believe i just watched an entire video about disassembling and cleaning a watch... 😳 🤣
Satisfying!
Nice video from a pro perspective. I did the same with a Timex Ironman 8 Lap from the early 90’s (?) and it really reminded me why I truly loved that watch. Great watch for working out and outdoor activities. I wouldn’t sell it for anything.
Je vous remercie pour cette vidéo très instructive ! On est loin du charme et de l' élégance de l'horlogerie " classique ", avec son étalage de l'ingéniosité humaine et je n'aurais pas été plus avant dans l'étude de ce genre de montre, sans votre travail !
As a newcomer to Casio G-SHOCK really enjoyed the video . I have an omega planet ocean quantum of solace watch which was never of my wrist from 2007 until he stopped in March this year . It was sent of to omega for a service and still not back 4 months later I needed a watch so got a Casio mud master which is an amazing watch but then started collecting G-SHOCK up to 5 now and stopped chasing omega up to find out when it will be sent back might even sell him as I have my eye on a few more and my girlfriend in on the act now wearing babyG which gets for more comments than my omega ever did . Thanks for the video will start watching all videos now a subscriber many thanks phil in Blackpool
Lol im with you have a couple of omegas too, same on the plannet ocean. Started off with basic mud master, built up to maharishi yellow strap version, red strap version, earth and acionn, mananged to ge t a frogman icerc,, love it for the colours,, love them, deffo collectable,, keep your collection, going
When I see that those supposedly 10 seconds per year ETA PreciDrive (thermocompensated quartz) movements have jewels (3 to 8, depending on the model), I’m always of two minds. Part of me is saying “quality!” and “it can be serviced!” and another part of me is saying, “I paid under US$200 for this Certina watch new, though the list price is far more, and service would consist of replacing the movement with a new one that’s $65 retail, so wouldn’t I be better off with a no-jewels movement like the one in that solar radio-sync Citizen watch I wore daily for ten years and still occasionally wear?”
If a watch is quartz-based and too cheap to be serviced (barring sentimental reasons such as being Dad’s), are jewels just points of failure? Maybe?
I’m stunned that the G-Shock case is so leaky! It looks as if it’s impervious but apparently it’s only as good as it needs to be… or rather, the delicate innards are safe behind that gasket, but the outer portions of the case are free to accumulate water and dirt in small doses.
Holy crap balls Batman, I live in Sydney and by my standards, you went to a really nice beach! Excellent.
Funny how you first talk this technological marwel down, and then give it a high score! It IS a marwel! Some of this video was painful to watch, but you made everything good in the end! Thanks for the video!!
Probably a good idea when you noticed the sand and dirt under the yellow case back would have been to stop and brush it off/ blow it off before opening the watertight seal. Some analogue g shocks also have the ability to set home points (with a series of button presses) for the hands and wheels, most likely in the instructions.
Wow so much patience and Skill. There’s something about you folks working on Watches, all those tiny Springs were making me nervous lol. Can you open up and clean a Gravitymaster GPW-2000. I liked how you gave the Coordinates of the beach at the end lol.
Lot of fun watching this. I've changed the batteries in my G a couple of times, but never went that deep into it. One thing, at the end when you are trying to get the mode wheels and hands properly linked... in the Casio manuals for the specific module (available for download), there is a step by step procedure to get everything properly aligned without physically working with the hands. It's different for every module, but anyone can resync without even opening the watch.
I own this exact watch and I love it. Has taken some pretty hard bangs at work and still perfect.
Hi Shane! Brilliant .... Good to know that your experience corroborates my demonstrations here. Thanks for taking a moment to say so. Richard
I used to scuba dive. After you've been to the beach it's extremely important to wash everything made of metal in fresh water to remove all traces of salt. In this case where it has a plastic over shield, leave it soak for half an hour with occasional agitation.
I would have been tempted to use a little rust converter on the rust stains. About 5% phosphoric acid for about half an hour. You can buy 85% food grade phosphoric acid and dilute 1:16 with a little distilled water. It does tend to leave bare steel with a blue/black patina (iron phosphate) but doesn't touch coatings (your mileage may vary). The bare steel can then be retouched with a little enamel paint or recoated to prevent further corrosion.
Hi Chris .... Yes my post salt water drills could definietely use a little improvement. Thanks for the tips on anti-corrosion, useful for these to be in the comments for everyone to read so thanks for that! Richard
I was wondering how on earth did the caseback rust in a year or two but salt water would do that indeed if not dealt with properly..
I wonder what that would do to the buzzer that's glued to the other side of the back plate though.
Your enthusiasm for this watch has caused me to order one, you rotten thing. Should arrive in a few days. 😊
Arrived today, really quick thanks to supplier and carrier. Love the watch. Navy blue version.
Enjoyed watching you, very zen. I collect 1970s twin quartz Seikos and want to start learning about working on them.
Hi Greg... Seiko Twin quartz is such a discerning niche sir! These are really excellent watches... be prepared for tiny pivots in the low torque power train. Enjoy! Richard
@@richardperrettwatchmaker thanks, Richard. I've spoken with two watchmakers about having my 9943-8000 serviced. One told me it would be a waste of time and money, the other said anything with a gear train should be cleaned and oiled after almost 45 years. Have to say I'm in agreement with the latter.
Very interesting. I thought for a moment that you had forgotten the markers. I have to say that, every time I see your Major watch, I can't help thinking of Faulty Towers...
"Faulty, is that you?"
"Yes, Major."
Hi Eugene .... Good to hear from you! Haha! Faulty Towers is such a classic! Richard
Thanks for this video! Absent of your watchmaking skills, a dirty and water-damaged G-shock would be unceremoniously introduced to the bin. I thank you for granting new life to at least one. But if you're going to clean and rehab one of the watch world's more economical brands, that "1965 Seiko-Matic with the dodgy bracelet" is absolutely entitled to some love!
Fantastic to see the level of miniaturization that casio achieved on electromechanical parts. Just some comments, The Spring on back is to make contact with the piezoelectric speaker attached on inner face of back metal plate. All g-shocks have same approach to electric ans mechanic connect the speaker. After the change batteries it is also necessary to enter on hands alignment procedure as described in owner's manual.
"My G-Shock is going to smell so good ". 😂😂 Reminds me of your un- boxing
of the Invictor pro-diver when you "sniffed" the box .
Great video as always Richard. By chance I was in Pembrokeshire last weekend visiting MHCG & one of the coastguards on duty was wearing the exact same watch ! I'm now looking to ad this one to my growing collection of Casio watches, my first being the vintage classic A203 Blue Thunder received as a present in 1980 which is still going strong !
Looking forward to your next video.
Hi Simon ... Comforting to know that the folks at Milford Haven Coast Guard are discerning about their watches! The Coast Guard and RNLI are important folks and always pretty busy down here. 'Gingers' is the place a nice coffee and cake in Milford ... I find myself in there quite a lot! Richard
Would absolutely love for you to open up a higher end gshock to see what differences they have internally please please do this
What's the difference between recklessness and courage?
Success. Well done, Major
I bought my first G Shock GA-2000 after I saw your first video about the model. It’s a great watch, and not long after buying it, I saw another color way-my first one is green with a negative digital display, and as I said, it’s great, but when I saw the same model in white with a positive display, I couldn’t resist it, so I bought it as well. Both my GA-2000’s have non-skeletonized hands, because I think they’re more legible..to sum up, the GA-2000 is a great design by. Casio, and your first G Shock video inspired me to buy it..I’m happy with my purchases.
G-Shocks are my guilty pleasures! Love the things.
Excellent video and really enjoy your Channel.
If you want to see what Casio can really do have a look at the Oceanus range! 👍
Richard,the yellow back cover is made of fibreglass reenforced resin and acts as a shock absorber!The grey rubbery thing is a shock absorber too!
Hi G Shock Babe614... Useful detail. Thanks for sharing it. Richard
Really great video. Thank you from a G-Shock owner. ⌚
Fascinating! Really enjoyed this video. Thank you.
One thing you missed, is that the pushers come out too.
Behind the button they have a cavity where their return sprint lives.
This place collects a lot of gunk too and here it'll affect the feel of the pushers too.
They also have tiny O-rings that can benefit from a bit of grease.
Having that centre spring electrically floating isn't a problem to these modules, it only handles the beeps.
What was probably happening is that the light pusher pushed the module out a bit, preventing it from actuating.
Usually these watches have a reset contact point, which you should connect to ground (the metal module frame) for a second after a battery change.
You can probably realign the wheels in software as the stepper motors have no way of keeping track of position and can drift when turning while receiving shocks.
It was cool seeing how incredibly well-built these fancier G-Shocks are.
I've dug DEEP into my GBX-100 in my modding adventures with it and it's nowhere near as well put together.
Same with the few cheaper non G-Shock Casio's I've taken apart, but all is relative as they stand far above the other cheap digital brands.
Good so see another video Richard, has been a while....👍
Thank you Richard for another watch anatomy class. Always enjoy the quality of your shots, your steadfast hands and clear narration in every video. So got me curious if you film, work on the watch, and narrate simultaneously. Or you just focus on filming and working on the watch, and dub your voice during editing? Anyhow really enjoy all facets of your videos and hope you will find time to produce more great comments and your Major watches.
I have the green one. Terrible to read and to operate, but very cool. I will remember this video when I need to repair it, although I don't expect that I will ever need it ;). Nice video.
Excellent video very interesting 👍 thanks Richard
Hi, I’m 14 years old and can already service a basic mechanical watch. What should I do to make my hobby a profession?
Hi ORB wheels and watches ... Learn as much as possible through reading and RUclips. Practice as much as possible on inexpenisve junk watches (ebay is a good source for old broken stuff). Set up a website (Wordpress is easy to do) and show your work on social media. Soon you will be taking on non-precious jobs for family and friends and in a few years you will get you first paid work for sure. Oh ... and don't work too hard; it's really important to enjoy your work! Hope this is helpful and good luck with it! Richard
@@richardperrettwatchmaker Thanks, I’ve already got speaking to a channel called CRM Jewellers and the video we made together should be released on Wednesday.
Bless you. The world sorely is bereft of capable watchmakers. Best of luck with your endeavor.
I really enjoyed this video, and btw, a very nice watch.
Very nice and superb video thanks for your efforts appreciate !
36:24 that wheel spinning looks pretty cool
Fascinating video. I am amazed with the quality of a simple G shock watch. It would be interesting to take apart one of the more expensive Master of G models like the Frogman GWF-A1000 or a really high end Oceanus model wihere the fit and finish of the case is similar to Grand Seiko watches.
Good one. If I attempted this, end of story.
Couldn't help wondering if they were Philips or JIS screw heads, but it worked.
Great video. Thank you for the detailed information on these fantastic watches. I love my G-shock.
Did you put the motors in the wrong locations the first time?
Precisely so Larry! Sometimes I am too focused on getting good footage and slip up on the job in hand. Well spotted. Richard
Thanks Richard. I didn't see any obvious shock proofing components. Am I missing something?
Hi Culture Vulture... The way the module rests inside the Carbon Core naturally provides a measure of isolation from shock as the module can shift around and then settle. This combined with the wider, less brittle pivots in the stepper motors stacks up to a pretty resilient package I guess. Hope this explains. Richard
How do you dispose of contaminated cleaning fluids?
Thanks for pulling one apart so I wouldn't have to to appease my curiosity. When are you 'going back in' to align the hands correctly? 😉
My pleasure! I went back in last night and its all good now. Glad you enjoyed this Laz! Richard
Very interesting. You should open some other tough quartz watches and compare it to g-shock, e.g. Citizen Ecozilla, yp2000... , Seiko Arnie....
Anyone know where i can get assembly diagrams for GA100 and also spare parts
thanks
You may have now to adjust Hans position with using the "hands set" function as you can find in it's manual. 👍 Nice video boys!
hello from a wet and windy Swansea on shore for a change ( and not enjoying it ) great to see some else from South Wales has taken to this hobby Im still picking up watches from free sources to play with
Would you be able to do a restoration video on a seiko 6602, or a seiko 7a38 if possible? Please
just curious if you know anything about watches with a fuseé mechanism
Hi Richard nice to see you back (:
I really enjoyed this. Thankyou
Great information. I have a Casio Edifice and I'm afraid to take the back off. Lol. Great job guy😁
Did you get something to rust proof the metal before the yellow back went on ?
I worked in the security industry and wore a G-Shock all that period. It was great as it took the knocks of hard everyday outdoor wear. Any other watch would have shown the scars of commensurate environmentalist age but not so the G-Shock. Most military and p0lice wear them as well, because G-Shock takes the heavy and often outrageous nocks the outdoor activity.
Hi, Richard. Did you do something relataded to watches in army? I'm curious.
Hi... Not at all. I was involved more with tanks! Our tools were a 'a bit chunkier'. Richard
First time here and glad I found it. Great content.. question? I am rowing the Atlantic from La Gomera to Tenerife. Approx 3000NM as the crow flies.. approx 40-50 days at sea. What watch would you recommend that could cope with that task? Robust enough for the daily dings. Good time keeping. Fit for task in hot weather, obvious wet conditions and features that would suit a crossing?? Also price point would be a factor.
Hi James, That is quite some adventure you have planned. Do you have any more information on this expedition maybe a website for example? Richard
@@richardperrettwatchmaker hi Richard.. have a look at the Tallisker Whiskey Atlantic Challenge. It’s the official site of the event!
Opened loads up over the years, I'd have scrubbed that back clean before opening though :)
Hi maxmixer! Yes.... Maybe that would have been the best way to go! Richard
well done... Just one note... That is the hour hand hasn't been placed exactly, in terms of direction, where it should be.
Hi there! Well spotted... I went back in and sorted that because it was bugging me. Also used the facility to sync the hands with the digital read out. Thanks for the feedback. Richard
I own a GW6900 which is solar and atomic. I run and swim in the ocean with it all the time. I was a little concerned to see how much water and sand ingress you got in your G, given that I don’t intend to open mine up and change a battery.
u can set the mode wheel in the whatch settings by holding the adj button for 5 secs
