Hey guys, I recently acquired this beat up 3714 and found some unusual things on the inside. The movement looks completely genuine, but case has some interesting things going on: looks like one of the screw holes for the caseback has been drilled (possibly to fit a different screw?) and the inside of the caseback looks like it has been modified a little around the inner circle. I'm wondering if any experts can tell me if 1) the case was a replica case that was use to fit this genuine movement or 2) if the case looks legit but just beat up and worked on by a bad watch maker. BTW, from what I know this is a very early 3714 - possible one of the first produced in early 2000s - so almost 15 years old already.
