"I stick food up my butt but let me tell you how weird my boyfriend is."
Anyway I wanted to talk about this old watch I used to wear: Casio w-5210-h (picture not mine)

I bought this thing in 2008, or thereabouts, and I have literally never seen the (tough solar) battery indicator show less than "high." The only reason I'm not wearing it anymore is that heat from leaving it in the sun caused the LCD to fade over the years, so I can't easily read it anymore
I still miss wearing it, though. Such a good watch. Last time I picked it up, after not being adjusted for multiple years, it was only about six minutes fast.
You can probably repair the old LCD screen. I've done it with a few old G-Shocks.
I'm actually working on something like that now.
My lovely wife got me a Seiko G757 for our first year anniversary, I repaired a gold Omega Tank clone for her.
Anyway, it worked pretty good for about a week. Then, overnight, some numbers started to fade. Then a day or two later, it was dead-dead.
The G757 is known for this because it was so cutting edge at the time, enough to be a Bond watch. The way it was made was very "We did a bunch of weird shit to make it work right and not be 3 inches thick."
Sometimes they just die. I was butthurt, of course. They're rare, she got a crazy deal on it, and it was even inscribed "Ich Liebe Dich." on the back. So it was a likely a gift from a wife to her husband way back when.
Anyway, I got some supplies and decided "Fuck it. It can't get more broken." I took it apart, and cleaned off the corrosion. The board was in far more exceptional shape than most I've seen. Basically new. But some traces were a little corroded. So I redrew them with a silver solder pen. Then, I did some testing. I kept a spreadsheet of findings, and I won't spam the thread with em, but I did find some hopeful things.
1.) After redrawing traces and testing every single tiny trace, the watch is good. Chip is good. The shitty incandescent bulb has been dead since I got it, but I reconfirmed. All voltage goes as it's supposed to, no dead traces.
2.) There are 4 upconverter condensers. These are little ceramic guys that die due to age. The way the watch got away with being so cutting edge but also thin is that each of these 4 controls a different quadrant of the screen. This is partially why you'll see old LCD watches that are missing chunks of numbers, or have dead sections of screen while everything else works.
3.) Testing the upconverters, they are all registering lower than they should, and one is completely dead. This would kill the whole screen, since they can't flash in sequence.
This is 90% likely to be what's wrong with the watch.
So I bought 500 of the correct size and rating condensers, and also some low draw amber LCDs. I'm gonna have to unsolder and then resolder 4 tiny guys about half the size of a grain of rice, and then replace that bulb with the LED. This should bring the watch to life, light the screen fully instead of off the side with a shitty incandescent bulb from the 70's, and also reduce power draw so the batteries work about twice the lifespan as before. Will tell you guys how it goes when the rest of the supplies get in.
Also the FrankenRolex build is going well.
