I got this one because it looked very old, big case, only two recessed buttons and a "time only" display.
Seller said "display is on, time not advancing".
Nice big watch :)

There's the problem, the thingy the setting button presses against is broken off!

Sticky goo on the ceramic circuit.

Minus terminal almost corroded away, even a track disconnected on the right of the pad.

I did some cleaning, some work with a circuit pen, and I discovered the quartz crystal was dodgy.
I ended up with this.

And it works :)
