I have a Russian wristwatch with what I assume is a vintage electric movement (transition between mechanical and quartz). It's attractive and it runs, and I want to keep it that way.
HOWEVER -
The old gasket has turned to sticky nasty goo, and the goo is holding the movement in the case around the inside of the dial. I don't want to ruin the movement or get the dial face dirty trying to get the assembly out of the case, but it's stuck in there tight. And I have no idea how to clean it once I have it apart. As a test I've tried letting the back parts sit in soap before washing them off. And when that didn't budge the tar, I tried GooGone - also to no avail.
Anybody with experience here, please help. Thanks!
