WPoste 0 Posted March 24, 2015 I've had a UN Marine Diver since January. Has spent most of the time on a wonder. Yesterday I noticed it had stopped two days prior with the power reserve indicator at full. After tapping it numerous times I was able to get it to start up but it would stop again within a half hour. I have gotten the power reserve down to 3/4 and the watch is now running fine for the past eight hours. Just curious if the watch had been overwound and this was the result. I have several rep Ulysse Nardins and one gen UN, and haven't had a problem Thanks for any information. Share this post Link to post Share on other sites
