About This Watch

Pre-owned. 1 owner's watch complete with orig. boxes, manual & dated paper. 

This highly sought after Sinn U1 diver's watch is in flawless condition. Case, bezel, crown & glass are perfect with the only flaw from on the outside of the buckle due to wear as one can find the usual faint hairlines here. The original rubber strap is very long & will need to be sized down for smaller wrists saving you some money. Unusually, the black PVC box is in splendid condition which is very pleasing so don't miss this watch, it doesn't come up often these days.

Pictures are actual watch & it has since been thoroughly washed to remove any dirt in the crevices.

Anti-magnetic & Water resistant to 1000m. The Sinn U1 is designed to be virtually impervious to water penetration. The material of the case is procured by Sinn from a steel supplier to Emden GmbH, one of Germany’s North Sea shipbuilding yards that construct submarines from the very same steel. This submarine steel is not only extraordinarily sea water resistant (PRE value up to 38), it possesses also the highest anti-magnetic quality. 
Because of the special steel used from the submarine steel manufacturer, and the use of Sinn's Tegiment technology, this bezel can be hardened up to 1500 Vickers instead of the usual 220 Vickers. The entire case also resists the effects of exposure to salt water environments.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel & treated to a black PVD coating which Sinn class it "Hard coating". The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. The international testing lab of Germanischen Lloyd has tested the U1, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.
