Have you checked the positional variance, sometimes a watch that is out of beat will run fine sitting flat but once you start checking in different postions the timekeeping can go way off. hope it's not the case, but should be checked face up, face down, crown up etc. hope you got luckygillsev said:Before I messed with it, it was running at -45 sec/ 24 hrs. After this "lucky" regulation, it is now at +4 sec/ 24 hrs. (against the atomic clock) and holding steady. I don't know about you but +4 sec/day is sure a lot better that -45 sec/day!
