I'm working on a cheap quartz watch. i changed the press fit crystal and the battery. The case back was glued on and now i'm having trouble finding what is the proper type of glue to use on a case back.
I've read a lot about gluing crystals, but can't find anything about gluing case backs.
My experience with epoxy is that, in general, it is very difficult to undo (for the next time you want to remove the case back.)
