Up for sale is my mint condition U1 S B, (S=black, B= blue). I am the original and only owner. The watch was purchased from a very reputable European AD. It has been worn very sparingly and is in terrific condition.
The entire watch is Tegimented and Sinn PVD/DLC coated. This is a terrific watch but has lately seen less and less wrist time.
After careful examination I found tiny hairline at the very edge of the clasp, (hard to see).

It will reach your door as a full kit: inner and outer box, tools, LocTite, links removed to fit my 7.0" wrist, and signed warranty card.
