So I have had my U1 now for just under a week and I believe I am having some issues with the crown.
There are, according to the instructions for the watch, 4 crown positions:
0 When the crown is screwed all the way in
1 When the crown is unscrewed counter clockwise to allow for clockwise winding of the movement
2 To adjust the date
3 To adjust the time
The issues I seem to be facing are with positions 1 and 2. Sometimes when I fully unscrew to position 1 it will do as expected and allow me to wind the watch. On other occasions I unscrew to position 1 and instead of the watch winding, turning clockwise adjusts the date instead so the date becomes wrong, even though I have not pulled the crown to position 2, all i have done is unwound the crown from position 0. On another occasion I did manage to pull the crown out to position 2 but winding clockwise did nothing. The date did not adjust and the crown was just spinning clockwise. On other occasions where I have unwound the crown to position one and the movement does wind when turning clockwise, position 2 does not seem to exist when pulling the crown. No matter how careful I am, when the crown does pull out one click it is on position 3 and the watch is hacked and it stops so I then have to reset the time when all I really wanted to do was adjust the date. When I then push it in one click from position 3, again position 2 intermittently doesn't exist and I am back to position 1 where clockwise just winds the movement when one click should put it at position 2 to adjust the date.
Do I need to send this back to Sinn to look at?
