About This Watch

Pre-owned but watch is mint & good as new. Comes with orig. boxes, manual & dated paper, under warranty. Watch is only a  month old!  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 who 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. 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.

Following the success of the U1 Tempus edition, The Hour Glass of Singapore created another model called U Black, an all black watch which was de riguer in 2008 & this special edition was made to just 399pcs. The success was partly due to it's very affordable price, large & well made watch. This has been sold out @ S$3600 after discount.
