My son who is studying for his masters in Architect only was going to wear this watch for special occasions.  The first time he wore it, he read the instructions but the watch would not keep time.  He lives out of state, so I do not see him often.  He brought it home this weekend.  I tried to set the time, read the instructions, pulled out the crown to position B, and push the crown to position A and start to wind clockwise.  When I did this the minute hand fell off the screw.  As you can see this watch has not been worn.
