Mine is running +30s/day, but I haven't been bothered to go have the movement serviced or regulated since the worst thing that happens is that I show up early somewhere, but that's better than running late. It's been four years since I got the Stowa though, so maybe it's about time.
Am currently waiting on delivery of a Seiko SKX007, so maybe it'll happen as soon as I have something else to put on my wrist.
