If i didn't know better, I'd say it's an fine excuse to post some great pictures of some beautiful watches, but I've had a similar experience of a watch suddely loosing or gaining 10 to 20 mintues in a day or so. Terrified, one set the watch, syncronising it with the most accurate at hand and watch it anxiously for the next twentyfour hours, hardly closing an eye. And then nothing happens. The watch go back to its usual rate of gaining or loosing.
So far, this is the best explanation I've heard. Thanks for posting it and the beautiful pictures.
Kind regards
Lars
