Next Wednesday I’ll be visiting Sinn HQ.
First to have my U1 checked for accuracy. When I got it it ran plus 3, which I think is ok. Gradually it kept gaining and now it’s at plus 8.
I was in touch with Sinn and they replied plus 8 is within tolerances and nothing needs to be done. However, my 104 plus 1, EZM13 plus 4 and obviously UX crazy accuracy per year.
For the same movement in 104 and U1 I think it’s a big difference.
Also power reserve is about 27-30 hours.
I decided to bring this watch in to have it sorted.
Second, I’m going to take a look at the 556 I B. I think I “need” a blue dial. And I want the watch to be different from a diver look.
We will see how this will play out. ![]()
