I just discovered that one of my case back screws has sheared off & now I'm looking to find out if anyone has any ideas on extracting the broken piece. It's broken off below the surface, so there's nothing to grab. Obviously, the water resistance is gone until I can get this fixed. Anybody got any ideas? Any way to seal the case back up & get some measure of water resistance back? I would really appreciate any help here guys. Too nice a watch to keep as a closet queen.
