Am seriously disappointed. On Friday I picked up my brand new Sinn U1 with fully tegimented case and bracelet.
What a great looking, great wearing watch. Wore it from then to now and there was a some variability in the timekeeping but it is an average of 15 sec per day fast.
That is hardly what I would call good timekeeping, I would call it below average for even a brand new Seiko 7s26. I've just returned it to Queensland (where the Sinn AD lives) to be adjusted. Thankfully that can be done for free.
I was told about how Sinn regulate each piece to +- 6 secs but mine clearly missed that regulation.
Nothing like having to return a brand new watch 3 days after purchasing it from an AD to be repaired. Might have to stick to Bremont for tough, accurate watches.
