I want to send mine in, but it's still getting slower (-33 seconds a day now), so I think I'll wait and see if it levels out first. Otherwise I'm concerned they will simply regulate it without fixing the underlying issue, and the watch will continue to slow down when I get it back.
I haven't been able to find anything on the interwebs about what might cause a watch to continue to slow down. Demagnetizing did nothing for me either.
Other than the fact that it's about as accurate as the cheap wind-up alarm clock I had as a kid, I really like the watch!
