Why We Like It The Sinn U1 came out of nowhere and blew the industry away with it's case being made out of German Submarine steel. This steel is stronger than stainless steel and is harder to scratch. The block style hands in red and white add a playful aspect to this very serious 1000 meters water resistance tool watch.
Notes Watch is running 0 to -1 seconds per day on our timegrapher. The watch is in great condition with a clean crystal and light scratches that can easily be polished out. We picked to leave the watch unpolished, but could have it polished for an extra fee. The watch comes with double Sinn boxes. The inner box is in rough shape, like most boxes of this age. Watch comes on a submarine steel bracelet which will fit comfortably up to a 7.5" wrist. Also supplied with a new Barton black rubber strap.
