I have had similar problems with my Overseas starting shortly after buying it on a cruise to the Carribean. It started by losing 2 minutes/day. I returned it to the store where I purchased it and it was sent to the Miami Service center for repair. It was returned to me after 8 months (they were waiting on a gasket from Switzerland). After being in my posession for 2 months, the watch would stop 5 minutes after coming off my wrist. When I couldn't get Miami to return my calls, I went directly to Geneva. They put me in touch with New York. I sent the watch to New York for repair, and after a "complete movement overhaul (which took another 6 months), it was returned to me. This time it took only 2 months before it stopped completely even while on my wrist. I returned it again to New York and received a phone call that THEY had no idea why the watch stopped, and they were sending it back to Switzerland. In the meantime, I have written to corporate offices in Geneva and received NO reply (I guess they don't care about their customers or their reputation). The watch was just returned to me after another 6 months (I have worn the watch about 6 months out of the 3 years since I purchased it) and when I opened the watch, the bracelet is broken and once again I am without my Overseas chronograph and it will be back for repair for the 4th time.
