That's amazing. I just sent my DS30 into Long Island for regulation. It was curiously - 20s/day when I sent it and now is - 10. As a Canadian I can't justify sending it over the border another time, so I'm hoping it fixes itself? Not sure what to do really.Just had my DA36 serviced by WatchMann. Previously it was +/- 5-10 seconds/day, but since the service it has been within +/- 1 second/day for the few weeks since it was returned to me. Worn every day.
