Seamaster running really fast gaining about 10min/hr!
I have an automatic seamaster that's about two years old and last week it started running really fast, gaining about 10 min/hr! I've let it run down and then tried to 'restart' it, but that hasn't helped. Anybody have any idea what's wrong with it?
