Sinn UX Einsatzzeitmesser 2 B (EZM 2 B) SDR – Officially Certified Chronometer.

Sinn UX Einsatzzeitmesser 2 B (EZM 2 B). SDR – this is a variation on the standard UX, but with black hardened tegimented rotating bezel. The UX is designed for the elite German Grenzschutzgruppe (GSG-9) special forces in underwater tactical operations. 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, 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, steel bracelet, The steel was by 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 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 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 is black hardened to 1,500 Vickers by the use of Sinn’s tegimented treatment in the Sinn laboratory. Outstanding watch. 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. Comes on silicone strap with folding clasp. Width is 44mm, lug to lug is 50 mm, Thickness is 13.5 mm.
