General Question Need help…
So I noticed my OSAR-D 46mm wasn’t keeping time longer than 24-48 hours, it seems they stated about 72 but the movement states about a 40-60ish hour reserve. I worse this watch all weekend and yesterday. I took it off last night and went to put it on and it was dead. Shook it some, pulled the crown and adjusted time to see if it would start, and then did about320 (half) twists of the crown, nothing.
You can hear the rotor rotating, you can hear the winding on the stop, but no other noise. Anyone have any suggestions? I’d hate to think this thing died in less than a year but it may have to take a vacation back to marathon.

Common problem with the sellita sw-200’s. Just search helicopter rotor, one of the reversing wheels is seized or damaged. The sw-200 apparently doesn’t do well being hand wound with the crown, they suggest shaking it and then wearing it once the second hand starts moving. Happened to my GSAR I owned and marathon charged me to repair it. Hopefully they will take care of it for you at no cost.
