This is my first Sinn and it arrived this morning. Excellent communication and service directly from Sinn. They seem to think of everything, not just the tool to adjusts the incredibly easy links and micros on the clasp but also the blue loctite to place on the thread when refitting the links.
I am sure I am preaching to the converted but this watch is a beast but in an extremely comfortable way. It's big at 44mm but I have sold 42mm watches that were too big and the U1 just isn't. I think this for a few reasons. Firstly the crown at 4pm means it doesn't dig into the back of my wrist as I wear a watch on my left hand. Secondly the lug to lug isn't overly large in comparison to the diameter and as you'll see from the photo it fits very nicely on my 7" wrist. Finally the micro adjustment makes it very easy to obtain a perfect comfortable fit.
It has some heft to it as you would expect but not in an unmanageable way but more of a feeling of a real presence watch on the wrist.
I really like the slightly darker colour of the bracelet compared to the non-tegimented version I tried on in Austria. If I want to be hyper-critical then there is a very minimal difference in colour between the bracelet and the case but I am really studying it and focusing on it to see it.
It's early days but I'm really happy with this purchase. Now the obligatory wrist shots:
