How to fix Seiko clock

[Randal5793]

I have a 80s Seiko world clock that I want to get working again. I put a battery in and it doesn’t work (obviously), I’ve taken it apart all the way to the circuit board and still can’t figure out the problem. I have a multimeter but I’m not to knowledgeable about it, but if I put the two ends on the ends and numbers start changing so I guess the circuit is working.... anyways I’ve ran out of ideas which is why I’m here, can anyone help me figure out the problem maybe one of you have hade this problem and fixed it, or maybe know a way I can rig another quartz circuit board to it.....anything is appreciated

Would you have some pictures?

The gears seem to be fine, they all spin freely.

I would love to be able to just buy a replacement movement , but can’t seem to find one anywhere, the model # for the movement I believe is 22001. So if anyone knows where I could find one that would be amazing.

I'll move this over to Electric Horology.

You might find one on Ebay that works.

I see a lot of green corrosion. Between quartz soldering points too. These corrosion cause electric leakage and the system will not work properly.
The plate must be perfectly cleaned, preferably with an ear stick soaked in ammonia.
After this procedure, the clock should move.
