Sinn 203 day/ date window help?
After some advice, as it looks like I may have damaged my Sinn 203.
About a week or so ago I noticed the date was stuck in between date change (it has a day and date). When I pulled out the crown it would not change over and it was not catching, spinning over. I wound the time back slightly and that seemed to resolve the issue.
Anyway, tonight I have pulled the watch back out of the box and now the date and day are changing 11 hours apart! The day seems in sync but the date is changing over at about 11 o’clock 11 hours later.
Any advice or assistance kindly appreciated!
