that there is only 1 pusher to change all data (Month, Day, Date, Year and moon). In fact, the watch is programmed to function where you live. So, did you buy your watch in Switzerland? Or from another country? You should ask JLC to re-program your watch. To be confirm by others Experts here. Nice watch. I sold mine (old version) because when I wore it by rotation, I every time had to make 1 push from each every day from watch stop to the current day/date.
and I did buy in Switzerland I don't recall it being wrong but has been some years ! I have it on the winder and is really nice (beside being a bit tricky to read even with good glasses) the glashütte much easier to read
if I am not wrong. You could check the correct time change, turning hour & min hands manually ;-) Hope it helps.
Your GO looks a couple days fast. My GO is within a day of accurate.
...so yes, it's wrong : )
unfortunately, a trip to the factory for a realignment of the module. Sorry. -Dean
