Verified Owner Comments: I am definitely a Sinn convert. I have owned Rolex, Seiko, and Cartier. This watch is just as beautiful and infinitely more tough. One thing to know about the U-1 specifically: the strap does not attach with a buckle it has a clasp like a metal bracelet. (The clasp is fully tegimented just like the rest of the watch.)
This was an issue for me at first because I actually use this watch to scuba dive, so I need to be able to adjust the strap depending on whether I am wearing it on my bare wrist or over a wetsuit. As it turns out this is not a problem. The clasp allows for several millimeters of micro-adjustment, so I was able to cut the strap to fit my wrist and still have no worries that I can expand the strap to fit over my wetsuit. I am very happy with this purchase.
Sinn offers the best value for the money, without a doubt.
