Box & Cert Dated July 2014, Local AD. The U1 is designed to be virtually impervious to water penetration. The U1 case 44mm is made from the same steel that is also used in the construction of the outer hull of submarines. This submarine steel is not only extraordinarily sea water resistant, 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 the usual 300 Vickers. Further, the entire case resists the effects of exposure to salt water and 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 SDR, 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 silicone strap with double push deployant buckle and fliplock safety clasp.
