I was winding my PAM 111v3 last night and as the watch was close to having full power reserve the crown suddenly started spinning without any tension and was no longer winding. When I pull the crown out out it does not set the time either, however the watch is still functioning. I took the crown guard off and the crown practically fell out but it's not connected to the stem, it's just the crown wheel. Is this an easy fix or am I looking at a few dollars to get it fixed or replaced? Thanks!
