Unbelievably the very same book came in to my PO Box as a gift about a week after this video was released to my Patreons, so a big thank you to the kind viewer and great minds think alike and all that😂 I now own 2 hard copies, but I know a home that will like the 2nd copy so it won't go to waste. I'm just pinning this comment purely because it may confuse the person who bought the book when I said in the video that I bought a copy!
Hello Vince I like watching you fix interesting things. I’m just wondering if you’re interested to buy two broken Wii off me and you can make a video of trying to fix them if you are interested let me know.
hi vince watched your channel for a while (albiet i did not sub) i have now as im after some advice or help, i was given a theorema watch from a friend 2 years ago as a gift, i was drunk about a year ago and managed to overwind it, and now it sits on my desk as i cannot get a shop to fix it without taking a bank loan out (delivery driver ).i bought a few watch repair tools ( i think i have everything i need) would it be advisable to try fix this my self? or some hints on how to replace the spring (i assume its spring), i opened it up undone winder screw a little as i heard its a nightmare to fix if totaly unscrewed. after a hour or 2 with magnify glass and untouched tools i thought it was best to leave it alone, any help or advice would be apreciated, or would you like to have a go at it on the channel i would pay if that interested you and would also donate a couple old watches (couple of them are self winders 1 sticks the other losses time ) and could dig out a few more, and im sorry for the bad grammer ,anyways hope to hear back as i do miss it and it has sentimental worth now.
For the Casio watch, to align the days with 2024, you can set it to the year 1996. Both years have 366 days and start on a Monday, so the watch will display the correct month, day of the month, and weekday.
Had a Timex LED in 7th grade. My friend asked what time it was. I pushed the button and it was 11:34. But from his perspective the display was upside down so it said "he:ll. He was a very religious kid and the look on his face was priceless.
To reduce ham-fisted damage, always neutralise battery corrosion fur with a light acid (eg vinegar), neutralise, rinse with distilled and dry (an ipa wash will help dry it if the unit can cope). Use a cottonswab for a bit of abrasion or specific placement of acid or use a wash to keep damage minimal.
The first watch was introduced to the world by Roger Moore 1973 in the movie “ Live and Let Die ". I remember when he pushed the button on the watch and it lit up in red digits. There was a huge reaction in the audience of the cinema. Nobody had seen a watch like this before, it was a James Bond gadget.
A DIGITAL watch. Digital! As in, it doesn't use a clock face! Nor clockwork! It never needs to be wound. It just shows you the time, in numbers! Amazing technology.
That first one is salvageable. Used to use silver putty for bond wires. You’d have to make sure all the traces are intact, though they’re gold so should be good. You’d also need to test the leds individually to make sure they work. The boots one maybe salvageable but all the traces were gone as not gold.
I normally don’t get religious but when you repaired the last watch which is the same one my dad gave me around my 16 th birthday I got so emotional. It brought back so many memories that were so wonderful. I still feel it on my arm. Yes I have the top of the range apple one now but I have such fond memories of the original.. Thank you. Love your stuff. Had to do another thanks😊
Vince, Some seven segment displays also included a decimal point that usually was not used. That would mean that there would be one contact for each of the seven segments, plus one for the decimal point, and one for the all important return line. That would total nine, or eight if there was no decimal on the number chip.
The LEDs on the Timeband watch are actually a nine segment display, for alpha-numerics, to show days of the week, as MO, TU, WE, TH, FR, SA, and SU. That's why there's nine bond wires on two of the digits. The common return is via the substrate.
Hey Vince, I can't say I've ever done a tooth check for metal/plastic quality 😂. It was really interesting seeing the bare silicone inside the first two watches. I agree with you that it's not practical/impossible to fix. Thanks for the video!
I remember getting an LED watch in the late 70s. Looking to see the time was a two handed job and the thing chewed through batteries. LCD was a huge leap forward.

What a fun coincidence, as someone that tried to love smartwatches so bad but got annoyed by them (especially the battery life on the apple watch), I picked up a Casio F-91W this week and I Love it, so I've been in a bit of a retro digital watch rabbit hole the past few days
The best feeling in the world is when these old digital watches spring to life. My cheaply bought and badly corroded Casio CA-901 is one such fine example of raising the dead. 😄
Interesting and cool watches :) Fascinating look to the LED watch electronics. I had a feeling the 80's watch will start right up with new battery, some time ago tried my 1989 Citizen ana-digi watch with new battery, and the digital clock started immediatly up, and even the analog watch worked for a while, I think dried or sticky lubrication may be the reason it doesn't work anymore. Interesting to see the 1983 watch calender was programmed so far in the future as my Philips VHS VCR I bought new in 2003 was programmed only up until 2017 :D I was also afraid those old batteries might explode as they were in such a bad condition. For some reason one LR44 battery exploded on me once, it had expanded and when I tried to remove it, it suddenly exploded. Luckily I putted safety glasses on when I saw the battery was in bad condition. Who knows, without them I might be blind now.
The white crusty thing is filler like the black thing around the chip, sadly it completely decomposed... it's not corrosion that built up, but it's the glue that they used to keep the digits in place.
It would be interesting to try a bit of Propanol in an ultrasonic cleaner and putting the watch in it .I have a computron with one segment missing keep thinking about using conductive paint to 'solder' it back to the gold bit but my hands are shaky
Blimey, I missed this one.. Maybe because it was my sisters birthday April 24? Anyhow no surprise the Casio worked.. The Timeband watch was a line introduced by the fabricators Fairchild in 75. Keep the watch as any Fairchild module will fit. Hughes aircraft made my favourite modules and they are fitted to dozens of brands. Some have alphanumeric messages. There were only a handful of LED module makers. I think someone said Fairchild were the first makers. They were not as far as I know.Hamilton Pulsar was the first commercially available LED watch with the Wrist Computer unveiled in 1970 on the Johnny Carson show - Three years before Live And Let Die. Kubrick had asked Hamilton to design a futuristic clock for 2001... The clock idea later turned into a watch.. Hughes apart from making the finest helicopters were making stuff for NASA and Apollo.. This was I guess a part of Apollo. I absolutely adore your channel. You do so well, I can confirm, having been an engineer for 40 years, you are better than many who claim to be professionals.
Nice one Vince 👍Such a shame that the first two watches were beyond repair but it was still great to see inside of them! I didn't expect bare chip dies, and was more expecting those bubble type displays not just bare LED chips. At least you got one out of three. Thanks again for the upload 🙂
I have that exact Casio watch! It was my grandfather’s watch. I took the batteries out so it didn’t get messed up. It is pretty dirty but it would clean up nice I think.
Nice fix on the LCD, the LED corrosion was fascinating, on two unrelated watches.1970's process contamination ? flux ? I had a Texas Instruments LED watch and the bond wires all fell off from the seven segs after five years, as a teenager it was an amazing insight into the technology. I had only worn it for a year but opened it up ~ 1980 uncapsulated, amazing. Comparing the watch screws to wrist watch revival you can see the cost saving by going digital. Ali Express sells a wire bonder for £5k. Thanks for showing a good bond wire bend, I was begining to think you were using too much muscle. And festive music to close.
The Casio was not a ladies watch, at the time of these being made, smaller was the thing, I had this & another casio that was black a sort plastic, that I use to wear when mechanicing to prevent getting shock / burns. They were cheap & cheerful. Have you considered doing what I've done in the past,🤔 I have swapped the inner working unit from case to case, & different make to different make, it can be a bit hit n miss, but if you've got a watch case / strap you love it means you can still get enjoyment from them👍
Great video Vince. Hoping you’ll try your luck with some more LED watches; the displays are literally brilliant (well at least compared to an unlit LCD). That book is excellent. Having very much enjoyed my own copy have ended up buying a few copies as gifts for friends with similar interests.
I have an led watch waiting for this treatment. It looks like it has overheated and has lots of corrosion. I will be trying white vinegar in my cheap not really ultrasonic bath. It just has a little vibrating motor like in a phone or games controller. It has one segment that works so fingers crossed.
Vince , the bond wires were in tact when you 1st put the IPA on in the close up on the 1st watch but that is the least of the worries with that one and the second .
The casio is great the others as you stated were to far gone ,i have a texas instruments calculator from 76 to far gone as it had a rechargeable battery pack in it and most of the tracks have been eaten through .
back in the 1970's watches for men and women were high in fashion now they now smart watches for all ages still classy and flashy too we have come long way 1970-2024 is going on on of our daily life style- keep up the good work-DLH
If it's possible to do so, I would advise trying to remove the watchstrap spring-bars without snapping them out of the case. It is very easy to snap the bar out, but leave the pin still jammed in the case. If that happens, you need to use alum to eat the pin away but could damage the case, have a very tiny drill bit, or try using heat on the case as a final option. There's no point in possibly making things worse before you start.
The first 2 watches were quite possibly salvaged by a dedicated professional, whereas that classic early to mid 80's Casio was a good bit of luck. As for the book, that looks like a youtube watch repair specialists video but in book form. Absolutely fascinating. Love the repost jokes though......
Vince you are correct a figure 8 would be correct, and the reason why you counted 9 connection points on the first watch is correct, as you would have 8 positive or negative wires, but you would also need 1 wire that is the opposite polarity. you were just thinking of the 8 wires to power the 8 lines. either that or if it is like you say each number is illuminated, then it would be the power for the light as the 9th wire.
This is a true story: A neighbour of mine took her watch to the jewellers, she had one of the LED variety press button type. When the jeweller asked her what was wrong she said that some of the little red bars had fallen to the bottom of the watch. The jeweller smiled and after changing the battery the watch worked fine.🤔🤭
Question! If you were to get an Ultrasonic Cleaner would that help with getting all that corrosion off more safe than with a soft brush? I see that most of those are literally falling off.
Love watch repairs the fiddly little one i love I watch another RUclipsr that takes apart watches cleans and put them back together and sometimes they just need a clean
I had a very similar watch to the Casio, but after a few weeks it forgot the number of minutes in an hour and hours in a day. Everything just went to 99! After a day or so it made my brain hurt, so got it replaced under the warranty! 44 years ago...
That glow through the corrosion - set me off on a fantasy about a sci fi movie in which a long distance cargo spaceship driver is steering through debris and sees a faint red glow coming from a passing rusted hulk. So he decides it’s worth a spacewalk either to rescue a survivor or find some treasure. But when he gets inside all there is, is huge blooms of acidic flora that’s been eating away at the electronics for centuries. But then he treads on a loose bond wire and the led patches briefly luminesce to spell out ‘help me’ To be continued…
Hi Vince, Spite fact this filmed in April *2024,* would be Awesome to Frame electronic pieces, showing delicate connections. Had idea for other items, but issue is Finding Magnifying glass or How, to bring view closer. let us know IF ever find such glass or way.
I have a Casio A 680 which I think is the same module. I Changed the battery at a watchmaker, also a renata, and it only lasted a few weeks. he also probably did not put the exact same type in. Did yours last? If yes I'll have to see what battery is in mine exactly and change it. I hope it's not some other fault.
Stuff they used to affix the bond wires is usually a gold filled epoxy which only needs a tiny drop to bond the wires, its damned good stuff esp if you are trying to fix something without soldering and there are variations of gold and silver infused glues but the old stuff they used took ages to go off in the days before superglues but nothing stopping you mixing in some metal filings into a bottle of superglue and have your own bonding medium.
With the first LED-watch i was wondering if soaking in vinegar would be helpful, but nah, they were too far gone it seems. A shame really, but still cool to see inside one of these! The bond wires and all, you dont get to see that nowadays.
That second watch you opened - What causes the corrosion is the acidic from the persons pH being on the acidic side and reacting to the metal...And It looks like it has been subjected to salt water.
Excellent, a MMV watch vid for the evenings viewing :D I am wearing one of my latest acquisitions, a flawless save for a scratched crystal 1970's automatic Avia with the unusual FHF 909 movement and it is keeping spotless time... best £16.50 I ever paid :D Also have incoming a 1924 trench watch with solid silver case and movement shield to go with my 1935 Rotary Meteor trench watch I got last week alongside a March 1968 Seiko Sportsman 6602 with a winkered dial but I snagged a clean replacement which arrived today and spending the evening regulating it as the Meteor keeps perfect time and someone knocked the regulator into max advance on the Seiko. If you ever get stuck for bits watchwise, dunno if you still got my email addy but I have a whole bedroom half full of odd bits and stuff, nothing high end although I have the beginnings of an Omega De Ville 1470 I paid £15 for en route... :D
Personally I like the watch repair videos. As for the boots watch, as I kid I used to like going to boots, they used to sell hi-fi stuff, computers and other electronic stuff, in fact we used to get our spectrum games from there, 😂😂
The first watch I think is from January 1974 with the 41 serial numbers as is the second one I use white vinegar and a cotton bud to clean corrosion in these old digital watches. it dissolves it nicely
For the first two I would have perhaps soaked the boards and LEDs in some white vinegar overnight, should clear that crud and some more of the diodes may have come alive.
The year thing. With the year wrong. The day of week will not be right. But choose the right year. Then the day ( Monday Tuesday etc) will line up for example 28 07 will be a Sunday once again

That style of metal bracelet on the first LED is certainly still in good shape and is somewhat collectable .

I believe bond wires are effectively spot welded, but with a tiny spot welder.
Casio watches are the best. Tut tut, Plastic tweezers for handling batteries. Great video.
Thanks for the heads up on the book, pretty sure I know how most modern circuits work but great to see how they were originally "innovatived"

The Casio should play “The Yellow Roads Of Texas” as an alarm tune
I had a Casio in the early eighties that looked like that one.
Used it for years, no problems.
That Red LED timex was my first watch, the batteries were terrible and run out after only a few months back in 1978
You can't win em all - very interesting and that last watch looks great =D
Vince , the bond wires were in tact when you 1st put the IPA on in the close up on the 1st watch but that is the least of the worries with that one and the second .
The casio is great the others as you stated were to far gone ,i have a texas instruments calculator from 76 to far gone as it had a rechargeable battery pack in it and most of the tracks have been eaten through .
I tried fixing these back in the days with very little to help me
Timeband was my first digital watch back in the late 70's
Quartz! Yes Vince. Quartz watches are great.
Boots and Woolworths used to have a whole section of these on sale. They were all the rage back then.

I've had Boots-branded cameras, projectors and all manner of electrical gadgets when they used to sell them in the 70s
For the LED ones I wonder if you could make/buy some new inwards?
I was thinking the same 👍 love that first watch, would be sad to see it in the trash.
That would be like triggers broom though
@@LOTPOR0402that first watch is also a very beautiful design too. Wouldn't mind having it with or without the original inside.
There's an ESA module on eBay at the moment that looks like the one in the 2nd LED watch. Listing shows it working.

If only there were some small board (PCB?) that you could put two broken watches on. They look really cool.
Love the videos Vince. I would have put the first watch in a bath of white vinegar left to soak for a short while. Not scraped or brushed.

Nice watches, Vince :)
I would like to have a 70's LED watch that still works, but never got the chance to find one that has no broken bondwires.
Thanks for the video, very interesting!
Those casios are pretty much bulletproof, i have picked loads up from car boots for next to nothing. Normally a new battery does the trick
That Casio is GOD TIER! 🥳🥳🥳
Those red LED display watches sure bring back memories.
Isn't it funny that now we have gone back to complety black faced watches.
"It's just a very very sweaty person! :D " -Vince 2024
I had a very similar watch to the Casio, but after a few weeks it forgot the number of minutes in an hour and hours in a day. Everything just went to 99!
After a day or so it made my brain hurt, so got it replaced under the warranty! 44 years ago...
You filmed the casio watch on my birthday

Whel if anything, you can recuperate the gold wires and the gold foil on the contacts and maybe make 1g and recuperate your spending and a little more
Hi Vince, Spite fact this filmed in April *2024,* would be Awesome to Frame electronic pieces, showing delicate connections. Had idea for other items, but issue is Finding Magnifying glass or How, to bring view closer. let us know IF ever find such glass or way.
When i used to work in a charity shop there where people who would still buy old vintage dead watches, and some of them paid decent money for them!.
I have a Casio A 680 which I think is the same module. I Changed the battery at a watchmaker, also a renata, and it only lasted a few weeks. he also probably did not put the exact same type in. Did yours last? If yes I'll have to see what battery is in mine exactly and change it. I hope it's not some other fault.
Stuff they used to affix the bond wires is usually a gold filled epoxy which only needs a tiny drop to bond the wires, its damned good stuff esp if you are trying to fix something without soldering and there are variations of gold and silver infused glues but the old stuff they used took ages to go off in the days before superglues but nothing stopping you mixing in some metal filings into a bottle of superglue and have your own bonding medium.
What is that polishing (looks like wool?) you used on the Casio case and bracelet?
Yes you can !! Haven’t watch the video yet. But I know you can
Very nice ❤🎉❤🎉❤
Poor little led watches. They’re on par of that cemented Omega. Maybe the body would be useful for a project?
With the first LED-watch i was wondering if soaking in vinegar would be helpful, but nah, they were too far gone it seems. A shame really, but still cool to see inside one of these! The bond wires and all, you dont get to see that nowadays.
It appears that 370 is the correct battery for the movement in the Casio A-880. 370 and 371 are equivalent.
My dad had a Casio watch like that in the early 1980's :)
I like the 70s cases I wonder if you can get new insides for the outter
Ah man, it would be so cool to have that Casio. I was born in 1980 and I'd leave the date set just like it is. Lol
That second watch you opened - What causes the corrosion is the acidic from the persons pH being on the acidic side and reacting to the metal...And It looks like it has been subjected to salt water.
Suggestion is to put a small mirror on the table then you don't have to keep flipping the watch over.
Excellent, a MMV watch vid for the evenings viewing :D I am wearing one of my latest acquisitions, a flawless save for a scratched crystal 1970's automatic Avia with the unusual FHF 909 movement and it is keeping spotless time... best £16.50 I ever paid :D Also have incoming a 1924 trench watch with solid silver case and movement shield to go with my 1935 Rotary Meteor trench watch I got last week alongside a March 1968 Seiko Sportsman 6602 with a winkered dial but I snagged a clean replacement which arrived today and spending the evening regulating it as the Meteor keeps perfect time and someone knocked the regulator into max advance on the Seiko. If you ever get stuck for bits watchwise, dunno if you still got my email addy but I have a whole bedroom half full of odd bits and stuff, nothing high end although I have the beginnings of an Omega De Ville 1470 I paid £15 for en route... :D
Personally I like the watch repair videos. As for the boots watch, as I kid I used to like going to boots, they used to sell hi-fi stuff, computers and other electronic stuff, in fact we used to get our spectrum games from there, 😂😂
The first watch I think is from January 1974 with the 41 serial numbers as is the second one I use white vinegar and a cotton bud to clean corrosion in these old digital watches. it dissolves it nicely
For the first two I would have perhaps soaked the boards and LEDs in some white vinegar overnight, should clear that crud and some more of the diodes may have come alive.
If you have an ultrasonic cleaner, it's a pretty efficient way of cleaning watches.
The year thing. With the year wrong. The day of week will not be right. But choose the right year. Then the day ( Monday Tuesday etc) will line up for example 28 07 will be a Sunday once again
I don't know why but I sense a follow up video for those led watches.
Let me know if you can find a place that still has those movements for that first watch a replacement
I love digital watches. When I was little I would use the old school light as a flashlight when I had to pee at 2 am.
Might be interesting to soak one of those corroded watches in a vinegar bath and see what happens.... Thanks for the insight
I would have loved to go back to 1980, at the beginning of 2020
I wonder if an ultrasonic cleaner would get rid of most of the corrosion on the first two watches - and make it clearer to see whats damaged and not
How about putting the two other ones in an ultrasonic bath ?
Thanks
Wow, thank you so much!!!! That's very kind of you😎
No idea, but would an ultrasonic cleaner have helped the two watches? Or would it have been too much?
I would like to purchase that watch, if you want to sell it. I have a couple now and would love to add to my collection. 👍 The Casio.
8:25 I would have soaked it in cleaning vinegar first!
one out of three ain't bad, that reminds me of a song I once heard 🤔...🤣🤣
Boots sold all sorts of things at one point I had my first walkman from there
