Outstanding! Superb watch worthy of such a fix. Amazing that you did such level of preparation over two months. I am sure the achievement outweighs all the frustration. Thanks for showing us this.
I know Im asking the wrong place but does any of you know of a trick to log back into an instagram account?? I was stupid lost my login password. I love any tips you can give me.
@Ricky Johnny i really appreciate your reply. I found the site on google and I'm in the hacking process now. Looks like it's gonna take a while so I will get back to you later when my account password hopefully is recovered.
It is amazing how you can bring something that would otherwise be trashed or neglected back to working order. There's not a lot of insightful videos out there for digital watch repair and you do a very good job in filling that void. I believe that those two frustrating months of repairing this watch have paid off for you, now that you learned something new, and also for your viewers, who may want to repair a complicated old LCD watch or even just a PCB. Keep up the amazing work and I'll trust that you'll hit 1k subs very soon and hit your next milestone shortly after.
Thank you for the positive comment. Yes some repairs are quite tedious but satisfying in the end, and stay tuned as I have lots more videos in the works.
Many thanks for the phenomenal video. Everything is perfectly described, down to the last detail, for us mere mortals to learn. Keep up the good work.thank you again
Late reply to a 4 yr old vid (excellent BTW). I did something very similar to this, maybe back in 2012 or so. The one additional check you could try to solve the remaining LCD segment issues, is to clean off the tiny contact spots between the LCD substrate and the zebra connector that presses on it. Use a toothpick with a tiny amount of alcohol on the tip, and carefully brush over the contact pads. It has certainly worked for me on many removable LCD panels. (Also, might I suggest investing in a trinocular scope, much easier to film and be able to study the subject in stereo vision !)
Wow working with super fine wires on a circuit has to be hard and if your hands shake its makes it much harder to do the repair.nice looking watch.i think I have a Novus red led watch in a chrome case
After watching many of your videos (fortunately I still have plenty more to watch!) I figured out most of the problems are for corrosion by battery leak. So, last weekend I checked out most of my watches to replace dead batteries or just take them out until I by a replacement. I don´t want to ever have to do the hard work you´ve done !!!! I keep on learning from you. By.!
I had a watch that looked like this but the watch ran on water instead of batteries , it was green but there was also blue and orange, have u read ever seen one?
Would love to see a repair on a Seiko a904-5xxx LCD watch as I have one in almost perfect condition except its gone very dim and I haven't a clue where to start....
@@VintageDigitalWatches Yes, you talk about a kind of "wire glue". But I would like to know a little more about the properties of that material... So it conducts electricity? Thinking about an electronic repair, the word "glue" causes some confusion to me about its final properties...
@@mariom308 Hi, I use the term wire glue because that is the commercial term for it so people know how to find it if they do a search on eBay. It is electrically conductive because it has to pass electrical signals. For detailed properties you would have to look up the Material Data Sheet for one of these products to get more insight.
I've been wondering about this kind of fix for some time now. But what I'm really wondering is if there is a coating you can apply to those ICs that don't have it applied for the manufacturer to protect those tiny wires??
I have thought about future proofing but I have to find a material that doesn't contract/expand while it cures or while it is exposed to temperature variations. If it did contract/expand it would end up pulling on the wire bonds.
I never saw anybody doing this kind of chip surgery before. Gold bonding wires are originally held into place by friction welding (because gold is very mallable). Thus instead of conductive glue (which can cause short circuits) a bonding machine would be the correct repair tool. Unfortunately AFAIK no small versions for workshop repairs were ever made (only laboratory chip rework stations those cost enormous prices). A proper tool would include at least a micro-manipulator (pantograph mech against shaky hands) and perhaps a laser to aim properly. I hope someday a small open source hardware version will be invented, that can be produced e.g. on a 3D printer. en.wikipedia.org/wiki/Wire_bonding
Hi, yes I did go through a few videos to see how wire bonding is done and checked some used machines on eBay but they are thousands. So I went ahead with the 20x microscope, and I do understand the concern of shaky hands as it is indeed very small room for error. Since the fix I upgraded to 60x ocular which make some difference. As for manipulators they are also in the hundreds and I make this kind of fix once a year at best so it is not quite worth it.
Hello, would you be interested in repairing my Casio DBC 63? I am a fan of your videos and the buttons on the watch do not work. Also the battery replacement I tried did not work. Looking forward to a reply, thanks. Jeremy
Hi Jeremy, I have quite the backlog because of viewers requests and will probably stay away from accepting so many fixes. If it the DBC 63 the you might want to try to clean the zebra strip that sits in between the keyboard and module, you can access it by removing the module. Regards, Tibi.
Vintage Digital Watches I have cleaned the part you talked about, but I found another problem. While putting the battery back in for a replacement, the backlight stayed lit and there was no display. Now I believe the battery has run out, and I have another one coming in the mail soon. When it gets here I will try to change it out but if that does not work then it is beyond my level of knowledge in digital watches. I am ashamed because this is my favorite model and I would have loved to get it back to a better condition. I know that you have a backlog of orders, and I am not trying to pressure you, but I will gladly wait if you want to take a look at it. I think it would be a nice video because I never see any about this watch model or it’s repairs. If not, that is fine and I might find a repair company that can take a look at it. All the best, Jeremy

There is no arguing that it was all worth it, and looking back it was a very satisfying experience.

@Ricky Johnny It did the trick and I finally got access to my account again. I am so happy!
Thank you so much, you really help me out :D
Master class in LCD repair,great video and what a watch!
Thank you for another excellent video. Two months of prep shows how committed you are to saving these watches.
I can't wait for your next video 🤗

Crazy fix! Very steady hands! Thanks for sharing... Koray
Thanks for the kind comment.
I'm about to try this on my Bulova LED. Thanks for making such a clear demonstration.
Fingers crossed :)
Learning a lot from your videos. Great work and keep it up mate!
Many thanks for the phenomenal video. Everything is perfectly described, down to the last detail, for us mere mortals to learn. Keep up the good work.thank you again
You are too kind with the comment, wish it could have been a 100% fix though.
Good work! And very interestig the process you follow. I never seen that watch before. Greeting from Mexico!
Hey, it has had a small production run. Cheers to Mexico.
Eye-opening video on how human hands working on microwires. Another great video for my night, thanks Tibi!
Thank you Eric

_This really is a _*_very special_*_ calculator watch!_
What an absolute gem!.....Excellent video and repair mate, thanks fo sharing this unique experience with us, Big Like 👍
Thanks you!
amazing! fantastic video, so interesting and informative.
You meant missing segments on the digits...excellent work.thanks for sharing.

Really out standing job.
Good video.
Just incredible. You are way past most watch makers skills on fixing digitals. Mine would certainly not touch this one.
Thanks you, they are a different breed of device as opposed to the mechanical masterpieces
Man, you're getting better and better ! Keep it up ! Saludos !

Amazing!! You are the Man!
Thanks for sharing

Thanks Simone!
I still have on my desk the Nelsonic space attacker with the same problem: missing wire bonds due battery leakage.A real pain...
Could pls share URL to the wire glue you decided to use for this repair?
I had a watch that looked like this but the watch ran on water instead of batteries , it was green but there was also blue and orange, have u read ever seen one?
Did you work before whith module casio cmd 40
Hi, i have led bulova watch computron that is running slow,is that a way to fix it by adjusting the like a potensimeter small bolt inside? Thanks.....
Hi, check the inside for the bolt, but the Compuchrons are notorious for oscilator issies ad they have a 700Khz one instead of the classic 32 Khz.
good job! i defintely need a microscope to repair such tiny things.
I cannot word out how important it was for me.
Would love to see a repair on a Seiko a904-5xxx LCD watch as I have one in almost perfect condition except its gone very dim and I haven't a clue where to start....
It is probably the capacitor used for generating the high voltage in the lcd driver.
wow... lo que haces es imposible!
In order to make sure the conduction, the glue did you use is a kind of conductor material?

Hey. Good Video. Can you answer me which battery you use / which battery is Right for this watch.
Thanks and greets from germany.
I have the same question. I recently purchased one and came with no batteries. Thanks!
LR44 seems to fit.

how much would you charge for a repair like this one?
Not somrthing I do as a service as it reslly depends on the watch, you ha e this exact watch pr something else?
@@VintageDigitalWatches I have a Texas Instruments 102 with a dead LED
Where do you get the wire bond replacement? You just mention where to get the glue, but not the wire itself.
From a donor watch, not the same brand, but still an old one that has the wire bonds exposed which allowed me to pick them off.
i see. thanks
