Sinn UX Einsatzzeitmesser 2 B GSG9 (EZM 2 B) â€“ Officially Certified Chronometer.
Sinn UX Einsatzzeitmesser 2 B (EZM 2 B). Long awaited and much talked about Sinn UX is now available but in limited numbers to start with due to the high demand for the watch. The UX is designed for the elite German Grenzschutzgruppe (GSG-9) special forces in underwater tactical operations. This one is branded with the GSG9 military logo and has the crown at the 10 position on the dial. It has a teflon based oil-filled cavity renders watch virtually indestructible, plus it eliminates glare and allows for reading from almost any angle. The refractive properties of the oil eliminates the glare and also gives the appearance of it not having any depth when viewed from an angle, so the time can be seen at even the slimmest of angles. It has the crown at the 4 position, tucked away out of the way as it is designed to prevent underwater snagging. A unique deep-water timepiece designed for extreme undersea environments. It is an officially certified chronometer and as such has been tested by the Swiss COSC independent testing labs under several conditions and tolerances. It comes with the chronometer certificate. Sand-blasted stainless steel case, anti-reflective and scratch-resistant sapphire crystal, hermetically sealed and screw-reinforced back, uni-directional elapsed time bezel calibrated for 15 minute decompression stops, reversed screw-down crown, teflon oil-filled watch cavity provides water resistance to virtually any depth, special ETA 955.652 quartz movement with seven year battery, quick-set date window, luminous hands and markings, shock-resistant, anti-magnetic, waterproof rubber strap, The steel was by procured by Sinn from a steel supplier to Emden GmbH, one of Germanyâ€™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 Tegimented where the steel can be hardened on up to 1500 Vickers. Compared to regular 316 L stainless steel which is hardened to approximately 220 Vickers. 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 watch has the bezel hardened to 1,500 Vickers by the use of Sinnâ€™s tegimented treatment in the Sinn laboratory. At times a pressure bubble can appear in the watch when it has been subject to pressure changes due to diving or cabin pressures during flights. The pressure bubble disappears within a few days as it stabilises back to normal pressure. Outstanding watch. Width is 44mm, lug to lug is 50 mm, Thickness is 13.5 mm. Comes on silicone strap with folding clasp. Ref: SIN 73a
