I don't know if I have a problem or not -- but I know I've never experienced such a noticable impact of position on timekeeping.
I just bought a Swiss Army Ambassador XL with the Unitas 6498. This is my first handwind since I had a Timex as a boy back in the 60s. It's also the first watch I've had with an 18,000 bph beat rate.
Since it's a new watch, I'm tracking it pretty closely. I like to know how a new watch performs.
So -- when I am wearing the watch it will lose time at rate of about 15 seconds per day. So far, about three days in, this seems to be pretty consistent.
Then, when I leave the watch face up over night, it gains time at about the same rate.
In fact, I wore the watch for about 12 hours yesterday -- over which time it gained about six seconds -- then I put it in my watch box. 12 hours later it had gained exactly six seconds.
Clearly, you can't ask for a better result over 24 hours, but I've never had a watch that would lose time on the wrist then gain time when stored.
Any thoughts on what's going on? Would regulation even help or would it just shift things to a net gain or loss if I follow the same wearing pattern? Might it settle down to a more consistent rate after some period of break-in?
I'm sure many of you in this learned community will have some thoughts as to what's happening. I look forward to reading your responses.
