Such perseverance! Congratulations👍. As others have commented, the vibrating 256 Hz "motor" is just the final stage of the dividing down network. By using only 5 stages of binary division from 8192 Hz (to get down to 256 Hz) - and then employing that resonant motor for the final stage - CEH avoided the large amount of additional power consumption that would have been needed if a chip was used for final binary division. These early binary divider chips were quite heavy power consumers compared to later CMOS ones! Interestingly, when these movements went back to Omega for repair later on in the 1970s, they seemed to routinely replace the 8192 Hz oscillator with a modern "32 kHz" version. Presumably because technology had moved on and the old chips may not have been available anymore. The customer would have been unaware of this of course; after all, it didn't change the functionality of the watch. I can vouch for this to be the case because I've examined such watches & personally measured the oscillator frequency: 32.768 kHz not 8192 Hz!!
Well I’ve been watching your videos for over 5 years and I have to say that was your best yet. Not just the fact that I’m stuck in bed with Covid but it had everything, High value, rare item, very complex and high risk repair and fantastic outcome. I hope it gets loads of views. You’re definitely not a “slave to the algorithm” Vince. No click bait titles. No gurning thumbnails. Just top quality content and what’s definitely needed to inspire other RUclipsrs to say no to the race to the bottom!
BEST VIDEO OF THE YEAR. Maybe one of the best ever. Incredible work Vince, can’t believe you’ve made the plunge over the years from item level, then board level, component level and now microchip level. Amazing, love love love it!
Haha, thank you so much Felipe!!!!! I got lucky with how the legs broke on this one. The break actually did me a favour. Glad you liked it, it was one of my favorites to date ❤️👍👍👍
It's really amazing what you can get working. I would've done what you did up until the legs breaking off. After that I would've put it aside and started looking for a replacement chip. You really go above and beyond on these repairs!
Thanks Roger. Long term I want to replace that board, or better still change the chip if anyone in the comments knows what it is. They are just do hard to source at the moment. If an alternative chip could be found it would save so many of these. Thanks for watching 👍👌
@@Mymatevince this chip is a simple counter that divide the crystal frq. to a lower one. can be easy done/replaced with a simple controller if you find one that is that small. can help you find one and program it.
Wooo! I've done reimplantating pawl and return fingers from Bulova Accutron into my Constellation B-21 literally yesterday! It was unforgettable 5 hours in my workshop. This things are on another level of complexity in comparison with common mechanical movements.
VINCE FIXED A WATCH!!! Oh mate that was exciting. That feeling you get when it runs is what I am addicted to! The brown thing is a trimmer to fine tune the quartz . I did a video recently where I my my mate Andy at the vintage Japanese watch company. He has seiko quartz testers . Amazing bits of kit. I tell you now mate not many watchmakers would have found and been able to fix that one. I am genuinely so happy for you . Incredible watch and now can be enjoyed again. Oh and you had me going with that crown at the end! Some accutron 218s have a particular way to remove and install the crown. Get it wrong it’s a complete dial strip down to realign. I only know this by virtue of having made the mistake more than once!
Haha, Ive done it at long last!!!!! Cheers Mike, how lucky was I. One of my fave videos to date. I hate putting in crowns, you're on the home straight and then that sinking feeling when you know it just didn't click in right 😂👍👍👍👍
WOW VINCE! JUST WOW! Excellent repair! I thought it was game over when the legs came off that chip. Very creative use of conductive paint! I was thinking of epoxy before you used the hot glue, but the solder mask will work just as effective. Well done, and an amazing job! Thanks for the shout out too! Really appreciated!
Congratulations Vince, unbelievable how you could rescue the power supply faulty bond wire, it look pretty messy but worked 😀 However, it looks like you murdered the trimming capacitor by trying to solder the sliding contacts on the ceramic silver metallisation... The motor, although tuned to the 256 Hz frequency by a moving mass, cannot be labelled tuning fork, because there is only one arm. That is why the whole watch body is humming! Making a tuning fork motor with opposite phase from one arm to the other would have cancelled this humming and maybe improved the efficiency (battery life) but not sure, because the microcircuit was made from bipolar technology, draining a lot of current. The ODC 5 is an evolution of the initial ODC 4 circuit used for the zero-th series (6'000 movements) sold initially. That first version is recognisable by the hex brass nut working as a trimming capacitor. I was born in Neuchatel and was 8 yrs old when the Beta21 was first released in 1967 but completely unaware of the unique and seminal work done by the CEH, 500 m from my home, whose engineers team built every component of that watch, including the integrated circuit, by hiring Swiss expats who had worked in the first semiconductor companies in the US after the 1950's. The CEH silicon microcircuit director, Kurt Hübner, had actually worked with William Shockley in his laboratory in Palo Alto.
More thrilling, suspenseful, entertaining, educational, gory and rewarding than anything that I've watched on Netflix for the past few months! The time just flew by watching this.
What a monumental achievement, Vince! If I could I'd give you a pat on the back and I'd think I wouldn't be the only one. The fact that you turned it around from the point of no return from what seemed to be the end of your attempt completely had me surprised. That, with a bit of out of the box thinking you were able to get an IC to return to the world of the living! That is an absolute feat and a testament to your skillset and determination. You have come far, that is something you should be very proud of. Congratulations, Vince. You thoroughly deserve the win! 🏆✌️
47:15 When you mentioned black nail varnish my first thought was, great iddea, it'll look like a blob chip. I think the solder mask does the trick though. Brilliant and epic FIX!
Vince, your channel is the best because I never know what you will be working on. It could be an electronics repair, work on the Rolls, fixing a boat or some other household item. Keep making these great videos!
Man oh man! What an odyssey! I was spellbound the whole time and couldn't look away. Congratulations, you have more guts than me I have to admit, grinding the chip is beyond me. Now you've got me thinking of buying one of those marvels!🤔 I already have a near mint 80 Micron gold f300 Constellation Chronometer (it does need work though). Is there no end to the madness that is watch collecting?😱🤪
The board you fixed contains on 8MHz cristal and capacitor. The chip has 3 functions. It keeps the cristal oscillating, it divides the frequency down with a 5 stage binary divider to 256Hz and it drives the vibrating motor (at 256Hz). The motor is just a see-saw with a permanent magnet on one side and a weight on the other side. The permanent magnet is placed between 2 electromagnets. You see the weight but the electro magnets are hidden under a plate. The oscillator drives the electro magnets in an alternating way making the see-saw swing back and forward. You called it tuning fork, but is actually not a tuning fork. The 2 fingers you see are actually just mounting points for the see-saw, not fingers of a tuning fork.. A gearwheel is driven by an index finger mounted on the rocking see-saw. The adjustment you made is an adjustment of the phase or neutral point of the see-saw. It is not used for speed adjustment. You can also adjust the position of the weight (by rotating it - it is mounted eccentric) on the see-saw. This adjustment is just intended to make the watch work, it is not to adjust the speed either. It allows you to balance out the see-saw. That way your watch uses the least energy. Speed has the be adjusted by an adjustable capacitor in the oscillator circuit (the capacitor looks broken on your board). Later quartz watches used stepper motors, no see-saw. Google "The Omega cal 1300 (Beta 21)" for a detailed explanation.
Wow, really interesting Kris. So when it was running fast at the beginning do you think the index fingers were just skipping teeth on the gearwheel because the see saw was misaligned? As I slowed it down without touching the capacitor. Thanks for the super helpful comment 👌👍👍👍👍
@@Mymatevince yes Vince, I think you can expect any whole multiple of the quartz clock speed when the mechanical part is not adjusted well - also the battery will drain more quickly. Borderline bad adjustment can also make the mechanism skip teeth sometimes - but this is really not the way you should be adjusting the watch.
@35:40 - Our 3 girls have a movie that really resonates with them called "The Sandlot". A line they use on me all the time is "You're killing me Smalls!" I've never seen the movie, but I love when they say it. I yelled this at the screen just now.
One of your best, truly magic amount of effort. One thing though, never never never use a magnetic screwdriver near ANY watch, especially one as finely balanced as a tuning fork watch.
Not strictly a tuning fork but a a see saw micromotor vibrating at 256Hz indexing a 256 toothed wheel via a little ratchet pawl. The caliber 1300 beta21 movement was only made for one year. Most modern Quartz watch crystals vibrate at 32768Hz
I do admire your perseverance, it's such a pleasure to watch your fault-finding logic. I used to repair mainly Hi-Fi for clients and time is money and pressure now I'm retired and have all the time to work on my own projects and it's such a joy to find workarounds at my leisure. Great video!
This is one of the Best so far. On the other hand early Omega Electronic watches were not long lasting. My Seamaster quartz bought in 1982 didn't last 10 years. My Wife's Roamer Quartz 35 Years & still ticking. BTW thanks 4 the Video. Greeting from Down Under.
As a watch hound myself this is really fantastic - it would be great if you could find another for parts and swap over the board with the chip and crystal but even if you can't you've brought this time piece back to life and seem to be enjoying it.
My heart skipped 2 beats when you poke the IC through the hole and broke the legs. That is some ironclad fortitude you have to even continue after that. If it was me, I would have just taken a break from it and come back a week later.
This was fascinating. We sometimes forget just how much genius engineering goes into the "simple" things in our lives. The grinding away part was very satisfying and I applaud your steady hand. kept forgetting just how tiny that chip was. haha.
Great job bringing an historical watch back to life . I have a bulova seamast which has the tuning fork movement I used the atomic clock app to check the time it gains 8 seconds a year
I have to say I am truly impressed, amazed, entertained and humbled to see such masterly but also human workmanship and craftsmanship. You are one of the most persistent men and one of the most patient I have seen or heard of. Plus you hands are incredibly steady. A rock would not compete! Truly brilliant work. Keep it up and. Love your videos generally but this was truly outstanding and the best yet!
Haha, cheers Duncanny. The secret to the steady hands is resting the wrists on the desk. Lucky the grinding tool is so light there is no strain on any muscles. Otherwise my hands shake with the best of them😂👍👍👍
Not the nicest? IT’S A GORGEOUS VINTAGE TIME PIECE.. GREAT JOB. I THINK this is the first video I think I was more excited than you when it started keeping time again… 😂CONGRATULATIONS!
Truly outstanding patience and dedication to that watch. I really did not expect that to be successful, but it just shows when you've nothing to lose. The grinding tool is amazing, definitely need one of those in my toolbox! Of course having a microscope and the patience of a saint helps! As you said, trying to find a replacement chip would be like looking for a needle in a haystack - top man, top fix, top video! Well done Vince, so happy you've got the timepiece of your dreams 😊
I loved this one! Your persistent and refusal to give - in inspires me to look further into the problem. Edisons quote: I haven't failed, I've just found 10,000 ways that won't work.
Hola I have been collecying watches since the 50's. I saw the transistor watch the Bulova turning fork and quartz. I know this movement very well. Congrats. Cheers Patagonia Argentina
Your video has frightened the life out of me. Ive been putting off fitting a new battery for months, as scared to see if mine works or not. Bought it at auction, probably a deceased persons item.
Wow, just wow lol! I honestly didn't think you could pull that off - consider me AMAZED lol BTW - if that little round component with 4 points is a trim cap, that probably helps adjust the timing.
Hahaha, I think the break of the 3 legs on the IC actually did me a favour as it was such a clean break. How lucky was I with that 😂😎 Do you know I didn't think to adjust the timing with the cap, maybe that is how you adjust it when you need a few seconds a day difference (which I do). Cheers Chris.
Oh wow...that was eventful! Now I know that I'm not insane to have done a similar operation to a pretty rare amplifier IC because the leg (or legs rather) was broken off! Wonder if there's a way to retrofit or make a custom board with off-the-shelf components of today...just to keep the remaining watches alive! Hats off to your effort!
excellent.. I work on mechanical watches and these early electrical watches are not commonly repaired... even if they are its usually just replacing the chip board. Great job!
Glad ive found this. Have bought same megaquartz watch, but with the leather strap with a clasp. No idea at moment if its just a battery. Fingers crossed.
Great video Vince you should get in touch with the nekid watchmaker on here and see if he has any idea of the chip or even a spare in his spares bin . loved this one whatever next lol .
I heard £800 and was like wow ,that’s a lot. But then you explain how you’ve been after one for quiet a while. And I realized, it’s a hobby you’re really into. So really it’s not that expensive. My hobbies and love is in cars . And I’d spend much more on parts or coil overs or even wheels. Which are way more in price. Hobbies can be expensive so I understand spending so much on them.
If it is a bond wire, then it not going to be fixed by melting. The chip is usually bonded using very fine gold wire which is ultrasonically bonded. Incredible that you got it working. Well done, Vince.
Woah dude that’s a very impressive video! I never expected you to work on something even more precise than the watch itself. The fact that you managed to fix a chip shows you that you can fix literally anything! I love this video! Great job! Congratulations on your beautiful new/old watch. The watch and the video are masterpieces! I really enjoyed it.
Amazing Vince! I felt the gut punch when the legs came lose from the ODC5 IC. I think it's some form of regulator or input output IC. The disk shaped item you resoldered is the "Quartz Motor Module" I think. That entire PCB may be called an "Electronic Module". The only thing I can think to do is cannibalize the IC from another broken item. No different than you stated.
Thank you buddy, I was gutted when it first broke BUT it did me a massive favour. I wouldn't have been able to get to the bond wires even with grinding from the other side as I would have ground away any trace of the wire. It broke so cleanly, and left the bond wires intact. A bit of a miracle on this one 😂👍👍👍👍
@@Mymatevince agreed! I took a risk with a conductive ink pin on the metronome video and ended up with similar success. I'm not sure how it will stand up over time, but last I checked it about two weeks ago the display was still functioning. Appreciate your problem solving on this one. I saw some listings for that watch going for $3K+ so I would say its a win for you if you choose to sale it one day.
Watch wiki says its a 5 stage divider. Turns the 8192Hz crystal into a 256Hz signal which drives the vibration motor (the technical term for those tiny arms). Divider chips are still made today and although this exact model won't be made anymore, a modern equivalent is likely to work. Edit: found a likely equivalent on Mouser. The NJU6369 is a 5-stage divider. Requires only 1.5V to operate. The chip package is the wrong pinout but an adaptor PCB could be made.
@@nhand42 Wow, thanks Nathan. I could always rewire it using jumper wires and solder mask it all into place. I will look into this chip. Thanks for doing this👍👍👍👍👍👍
Great video yet again Vince, maybe you could look into getting some UV cure nail varnish, my wife uses it on her nails and it cures pretty well, just a suggestion, keep up the good work 👍🏻
That was an excellent repair! I could also say a bit lucky too!! I do the same stuff as you and im also ex BT, so it must be something about tinkering with phone systems for years!! nice one Vince
Hi Vince, I'm a big fan of your videos and enjoyed this one very much. I'm not sure if anyone has mentioned that the movement is more likely to be an Accutron movement than a beta 21. The giveaway is the sweeping second hand, where I believe the beta21 is a quartz movement which "ticks" once a second. Looking forward to your next adventure with the RR.
Amazing work Vince, I would have no way thought of trying the conductive paint. Like you say with that conformal coating on it looks just like a blob chip. Keep up the great work.
@My Mate VINCE this chip is a simple counter that divide the crystal frq. to a lower one. can be easy done/replaced with a simple controller if you find one that is that small.
This was awesome vince, you should do a series of Watch repairs and builds, would love to see you buy a cheap nh35 movement strip down completely and rebuild and I’m sure you could do it 👍 great video my heart sank when I heard the crack 😫 but cracking repair 👍
Great job Vince. Didn't expect to see a microchip repair. I'm guessing the heat affecting the chip from outside pointed to a bond wire break on the outside terminals of the chip. Maybe if it was a break from the center, outside heat wouldn't of had quite as much of an effect as it did. You would probably have to heat it directly to get it to work. Nice work again Vince, that was really interesting to watch 😉
This one was a rollercoaster! You never cease to be amazing, turning your hand to quite literally anything. I love the perseverance. This one was a real cracker and really shows all your skills to the fore, the culmination of years of doing this sort of thing. Brilliant Vince, keep it going!!
What impresses me on your videos is where you continue to persevere where a lot of people would give up. At the point when the chip broke, that's when I'd have thrown the towel in, but no. Very impressive video. Also, you have to love the dichotomy of having purchased an £800-not-working watch, while wearing a basic Casio digital. 😂
Wow, you really do keep a buffer of videos to post 😂 I saw on your Casio that this was filmed on the 23rd which was a Friday. So September? You should have seen my face when the chip collapses under the soldering iron. So much emotional pain!
Yes, this one was a bit delayed in releasing. Sometimes I release the videos as soon as they are done, sometimes I hold onto them depending on what was released previously. For example I wouldn't want too many tea break repairs together 👍👍👍
@@Mymatevince yours is my favourite channel on RUclips. The videos are very high quality with lots of learning potential. I hope they never stop coming.
I used to own a bulova accutron with the tuning fork I think they were the first ones that made the tuning fork it was so accurate and the hum was so unique with the smoothest hands sweep , wish I had kept it now instead of swapping it for another watch. Just to let you know a seller from eBay from Bulgaria deals with tuning fork watches may have a part his eBay name is anticvarius
Such perseverance! Congratulations👍. As others have commented, the vibrating 256 Hz "motor" is just the final stage of the dividing down network.

Cool watch, scary repair. Gutsy. Congratulations on your success and bringing back a piece of watch history
Great job bringing an historical watch back to life . I have a bulova seamast which has the tuning fork movement I used the atomic clock app to check the time it gains 8 seconds a year
I have to say I am truly impressed, amazed, entertained and humbled to see such masterly but also human workmanship and craftsmanship. You are one of the most persistent men and one of the most patient I have seen or heard of. Plus you hands are incredibly steady. A rock would not compete! Truly brilliant work. Keep it up and. Love your videos generally but this was truly outstanding and the best yet!
Haha, cheers Duncanny. The secret to the steady hands is resting the wrists on the desk. Lucky the grinding tool is so light there is no strain on any muscles. Otherwise my hands shake with the best of them😂👍👍👍
Just shows what can happen when you keep moving forward...GREAT FIX VINCE
Lol things got a little chaotic there but man that’s such a clever fix!! I’ll definitely store that info away
Thanks! Very interesting fix. Delighted you got it sorted.
Thank you so much Adam 🍻👍👍👍
The boat first and now the watch. You are the first to ever give 2 Super Thanks 👌
Not the nicest? IT’S A GORGEOUS VINTAGE TIME PIECE.. GREAT JOB. I THINK this is the first video I think I was more excited than you when it started keeping time again… 😂CONGRATULATIONS!
Thank you 👍👍👍👍
Vince,
I was on the edge of my seat with this one. Great vudeo!
For the first I was at the edge of my seat and curious, in the middle terrified and by the end I was EXAUSTED! Lol. Incredible. Great vid Mr. Vince.
Hahaha, thanks AJ!
Amazing, like most comments I would have given up long before I got close to what you did.
Way to go Vince, another great video and fix.
Truly outstanding patience and dedication to that watch. I really did not expect that to be successful, but it just shows when you've nothing to lose. The grinding tool is amazing, definitely need one of those in my toolbox! Of course having a microscope and the patience of a saint helps! As you said, trying to find a replacement chip would be like looking for a needle in a haystack - top man, top fix, top video! Well done Vince, so happy you've got the timepiece of your dreams 😊
Thanks Midinotes👍
I loved this one! Your persistent and refusal to give - in inspires me to look further into the problem.

Hola I have been collecying watches since the 50's. I saw the transistor watch the Bulova turning fork and quartz. I know this movement very well. Congrats. Cheers Patagonia Argentina
That's a beautiful watch! And as a thin-wrist guy, I totally appreciate the fight to secure a heavy watch.
Aw well done I really thought it won't work after the chip had broken but well done you got it working once again amazing
Your video has frightened the life out of me. Ive been putting off fitting a new battery for months, as scared to see if mine works or not. Bought it at auction, probably a deceased persons item.
Very Well Done Vince, I definitely thought it was game over whenever that chip collapsed. A big Kudos to you for saving the day. Mick. 👍👏🍻
Thank you Mick, the broken chip ended up saving the day as it exposed the bond wires. Unbelievable lucky on this one 😂👌👍🍻
Wow, just wow lol! I honestly didn't think you could pull that off - consider me AMAZED lol BTW - if that little round component with 4 points is a trim cap, that probably helps adjust the timing.
Hahaha, I think the break of the 3 legs on the IC actually did me a favour as it was such a clean break. How lucky was I with that 😂😎 Do you know I didn't think to adjust the timing with the cap, maybe that is how you adjust it when you need a few seconds a day difference (which I do). Cheers Chris.
Well done!!! Held my breath while you were doing the microchip repair! By far the most Exciting and reverting watch repair video I've seen to date👍🙌
Wow, thank you!
This was really enjoyable. As you say, troubleshooting the chip connection was excellent work!
What an amazing fix! I really like this watch. I think it looks really good.
Oh wow...that was eventful! Now I know that I'm not insane to have done a similar operation to a pretty rare amplifier IC because the leg (or legs rather) was broken off! Wonder if there's a way to retrofit or make a custom board with off-the-shelf components of today...just to keep the remaining watches alive! Hats off to your effort!
Haha, thanks Rui 👍👍👍👍
Certainly one of your best videos - the chip repair is great and so interesting. And watches like that deseve to be used
Thanks Dave👍
excellent.. I work on mechanical watches and these early electrical watches are not commonly repaired... even if they are its usually just replacing the chip board. Great job!
Great video there vince that repair was the best one that I’ve seen so far
Thank you Max! 👍👍👍
When you brought out the grinder I thought, "Oh, he's bunged it up!" and then....!!!! Amazing video!
😂👍
Glad ive found this. Have bought same megaquartz watch, but with the leather strap with a clasp. No idea at moment if its just a battery. Fingers crossed.
These types of fixes are my fave cos they're the same I would do, sure it's not pretty but it works!
Great video Vince you should get in touch with the nekid watchmaker on here and see if he has any idea of the chip or even a spare in his spares bin . loved this one whatever next lol .
Fantastic video you got it working. Congratulations Vince you are the Man.
Wow.. congrats on that teeny tiny work. I need to get some of that paint now.
15:45 You can see the watch running after soldering the top middle pin. Well done!
I was very skeptic at the beginning, but at the end I would say, a watchmaker wouldn't came up to this result. Nice work!
I heard £800 and was like wow ,that’s a lot. But then you explain how you’ve been after one for quiet a while. And I realized, it’s a hobby you’re really into. So really it’s not that expensive. My hobbies and love is in cars . And I’d spend much more on parts or coil overs or even wheels. Which are way more in price. Hobbies can be expensive so I understand spending so much on them.
Well done, thought you might be beaten this time, well done for persevering!
If it is a bond wire, then it not going to be fixed by melting. The chip is usually bonded using very fine gold wire which is ultrasonically bonded. Incredible that you got it working. Well done, Vince.
Thanks Ned, glad I didn't heat it up now 👍👍👍
Woah dude that’s a very impressive video! I never expected you to work on something even more precise than the watch itself. The fact that you managed to fix a chip shows you that you can fix literally anything! I love this video! Great job! Congratulations on your beautiful new/old watch. The watch and the video are masterpieces! I really enjoyed it.
Thanks Jason👍👍
@@Mymatevince You're welcome! Keep it up, you're doing an amazing job.
M8, there is nothing I can add on top of the other comments.
Perseverance should be your middle name, amazing fix. 😁👍🏻👍🏻👍🏻👍🏻👍🏻👍🏻
Thank you👍👍👍
I just happened to be reading about the early quartz watches, including this one, a few weeks ago. Nice coincidence to see this video!
So satisfying to get something so tiny to yield to such a macroscopic fix.
Well done🥰
Your learned more from the first video-you've got gloves & you know what that little black box is---AND YOUVE GOT GUTS SOLDERING!
Nice ending and very good problem finding.
Brilliant video! The part you seek is Omega 1300.9035 If I had one, I'd give it to you...for the price of postage of course!
👍👍👍
Dear Mitch, I allso seek for Omega 1300.9035 it is posible to have one, I will pay for them.
nice fix Vince. very enjoyable video. my heart sank when you pushed the chip in and it broke. 😢😢😂😂
This is a very good video, it feels like watching an adventure.
Amazing Vince! I felt the gut punch when the legs came lose from the ODC5 IC. I think it's some form of regulator or input output IC. The disk shaped item you resoldered is the "Quartz Motor Module" I think. That entire PCB may be called an "Electronic Module". The only thing I can think to do is cannibalize the IC from another broken item. No different than you stated.
Thank you buddy, I was gutted when it first broke BUT it did me a massive favour. I wouldn't have been able to get to the bond wires even with grinding from the other side as I would have ground away any trace of the wire. It broke so cleanly, and left the bond wires intact. A bit of a miracle on this one 😂👍👍👍👍
@@Mymatevince agreed! I took a risk with a conductive ink pin on the metronome video and ended up with similar success. I'm not sure how it will stand up over time, but last I checked it about two weeks ago the display was still functioning. Appreciate your problem solving on this one. I saw some listings for that watch going for $3K+ so I would say its a win for you if you choose to sale it one day.
Watch wiki says its a 5 stage divider. Turns the 8192Hz crystal into a 256Hz signal which drives the vibration motor (the technical term for those tiny arms). Divider chips are still made today and although this exact model won't be made anymore, a modern equivalent is likely to work.
Edit: found a likely equivalent on Mouser. The NJU6369 is a 5-stage divider. Requires only 1.5V to operate. The chip package is the wrong pinout but an adaptor PCB could be made.
@@nhand42 Wow, thanks Nathan. I could always rewire it using jumper wires and solder mask it all into place. I will look into this chip. Thanks for doing this👍👍👍👍👍👍
@@nhand42 the more you know! I'll start looking for Watch Wikis myself. Thanks for sharing.
Great video yet again Vince, maybe you could look into getting some UV cure nail varnish, my wife uses it on her nails and it cures pretty well, just a suggestion, keep up the good work 👍🏻
That was an excellent repair! I could also say a bit lucky too!! I do the same stuff as you and im also ex BT, so it must be something about tinkering with phone systems for years!! nice one Vince
😂👍👍👍👍
Amazing journey this one Vince. Thought it was a gonner after that chip went through. Glad it worked out - it's a lovely watch
Thank you so much Jon 👍👍👍
Hi Vince, I'm a big fan of your videos and enjoyed this one very much.
I'm not sure if anyone has mentioned that the movement is more likely to be an Accutron movement than a beta 21. The giveaway is the sweeping second hand, where I believe the beta21 is a quartz movement which "ticks" once a second. Looking forward to your next adventure with the RR.
Amazing work Vince, I would have no way thought of trying the conductive paint.
Like you say with that conformal coating on it looks just like a blob chip.
Keep up the great work.
Thank you Adam👍👍👍👍
brilliant stuff. My one attempt at fixing a watch ended up with a scrap watch
@My Mate VINCE this chip is a simple counter that divide the crystal frq. to a lower one. can be easy done/replaced with a simple controller if you find one that is that small.
Thanks Itai 👍👍👍👍👍
This was awesome vince, you should do a series of Watch repairs and builds, would love to see you buy a cheap nh35 movement strip down completely and rebuild and I’m sure you could do it 👍 great video my heart sank when I heard the crack 😫 but cracking repair 👍
You are a step above in repair. Insane.
Wow Vince that deserved a double thumbs up
Great job Vince. Didn't expect to see a microchip repair. I'm guessing the heat affecting the chip from outside pointed to a bond wire break on the outside terminals of the chip. Maybe if it was a break from the center, outside heat wouldn't of had quite as much of an effect as it did. You would probably have to heat it directly to get it to work. Nice work again Vince, that was really interesting to watch 😉
Thanks Anthony👍👍👍
absolutely awesome , lovely watch and you fixed it , welldone to you sir
I think it looks classy . I like vintage chunky watches though . Amazing fix , I thought it was all over when the chip pushed through the board 👍
This one was a rollercoaster! You never cease to be amazing, turning your hand to quite literally anything. I love the perseverance. This one was a real cracker and really shows all your skills to the fore, the culmination of years of doing this sort of thing. Brilliant Vince, keep it going!!
Thank you so much Dazzy!!!
What impresses me on your videos is where you continue to persevere where a lot of people would give up. At the point when the chip broke, that's when I'd have thrown the towel in, but no. Very impressive video.
Also, you have to love the dichotomy of having purchased an £800-not-working watch, while wearing a basic Casio digital. 😂
Hahaha, so very true on the Casio! Thanks for the kind words 👍👍👍👍
Wow, you really do keep a buffer of videos to post 😂 I saw on your Casio that this was filmed on the 23rd which was a Friday. So September?
You should have seen my face when the chip collapses under the soldering iron. So much emotional pain!
Yes, this one was a bit delayed in releasing. Sometimes I release the videos as soon as they are done, sometimes I hold onto them depending on what was released previously. For example I wouldn't want too many tea break repairs together 👍👍👍
@@Mymatevince yours is my favourite channel on RUclips. The videos are very high quality with lots of learning potential. I hope they never stop coming.
@@sdjmchattie Wow, thanks Stuart. High praise indeed👍👍👍👍👍
I used to own a bulova accutron with the tuning fork I think they were the first ones that made the tuning fork it was so accurate and the hum was so unique with the smoothest hands sweep , wish I had kept it now instead of swapping it for another watch. Just to let you know a seller from eBay from Bulgaria deals with tuning fork watches may have a part his eBay name is anticvarius
Thanks Joseph 👍👍👍
