I recently purchased a 292 from another member and last night, I decided to open it up to clean up the inside of the crystal. I am afraid that may have turned out to be a big mistake. Everything was going well until I tried to wind it. I did some reading, and my guess is that I unscrewed the crown's screw too far. I'm feeling like I'm in over my head, but is there anything that I can do to fix what I seem to have done? I really don't want to lose this watch for 2 months while I wait for a service - I'm kind of in love with it!
