WATCH POP

I took delivery on my Seamaster Professional in Aug 04. After wearing the watch for a few days it settled into running +3 sec/day. When the weather started to get cold (Chicago,IL) the watch began running +7-8 sec/day, outside of COSC rating.

My problem, I wore my SMP in a hot tub about a month ago and has since run -6 sec/day. Is there anything I can do to improve the accuracy? And, are these wide variations common with change in temperature? IMHO, your watch is ok. If you want better accuracy in a consistant bases, only quartz can beat that.

I doubt it has much to do with the temperature, since your body temperature is pretty much constant, and after you took it off, the watch is indoor anyway. My new SEMP certified chronometer is doing a consistant +16 seconds a day after 4 weeks. I am taking it to the official Florida Omega service center Wednesday for an adjustment. According to the service center they WILL adjust it or replace the movement. The same week I bought a new Ernst Benz automatic GMT, non-certified, and it has been keeping +3 seconds a day. You never know!!!

NWF My SeMP is running consistantly +1 sec. a day after having it for 5 weeks. Omega 3520.50, 2538.20, 2531.80, Tag-Heuer Formula 1 Chrono, Luminox Navy Seal My SMP too is keeping a constant +1 second per day after 6 weeks of wear. Based on some of the forum members comments about timing, I have tried putting the watch crown down and crown up on different evenings. One evening with the crown up, I lost 2 seconds.
Although the watch is a constant +1 second per day, I have been able to manipulate the watch into only being ahead by 10 seconds after 6 weeks. I don't suffer from insanity ... I enjoy every minute of it!
