While waiting for parts for another watch, I decided to get to work on another one that had turned up. The owner wanted new seals and battery and asked me to see if I could fix a problem with the setting mechanism. It's a nice Seiko quartz diver, you can see the state of the crystal, and the dial underneath is in excellent condition, although it's hard to tell in this shot. Caseback is in good condition, doesn't look like anybody has used scissors or circlip piers to open it. First thing is to open it. Movement looks OK, no signs of water entry or battery leakage.
