Model:: U1
Description:: The U1 is designed to be virtually impervious to water penetration. The U1 case is made from the same steel that is also used in the construction of the outer hull of submarines. The steel was 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. 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. The watch has an automatic mechanical movement, operating at 28,800 beats per hour, shockproof according to DIN 8308 specification and anti-magnetic according to DIN 8309 specification. Matte black dial with date at 3, Super Luminova on hands and markers, and striking red seconds hand complete the design. Other features include sapphire crystal with anti-reflective coating, and rubber strap with double push deployant buckle and fliplock safety clasp.
