Sinn U1000 SDR Automatic Chronograph

This is like the regular U1000 but modified at Sinn to incorporate a black tegimented steel rotating bezel. Other than the black bezel, it is the same as the regular U1000. The Sinn U1000 is a world first in the watch industry in that it fulfils the European diving equipment standard. Its reliability, accuracy and faultless operation, even under extreme changes of temperature have been subject to review and testing and duly certified by Hamburg based institution Germanischer Lloyd, who have the responsibility for technical safety in the maritime world. Germanischer Lloyd have certified the pressure resistance of the U1000 to 100 bar or 1,000 metres. The U1000 is and outstanding diver chronograph with an unmistakable character. It is a watch with special capabilities and technologically advanced features, unlike any other available today. In its design too, which as with all Sinn watches, is guided strictly by function. The U1000 projects and imposing presence: tough, well constructed and guaranteed to work. These are essential qualities for anyone who wants to ensure that their personal safety will be reliable every day, and even under extreme diving conditions. The watch has an optimised chronograph display. Technically, Sinn have nothing to chance, every little detail meticulously planned. At the heart of the watch is a calibre SZ 02 automatic movement. This was developed and manufactured for functionality with the chronograph indicator at 6 o'clock position which is more prominent and logical to see, in a very large sub dial. It is on a 60-minute counter - and not as usual on a 30-minute timer. These combined make for a highly legible display. This practical design has an unbeatable advantage: With support from the 12-hour meter for hours can be at a glance the chronographs stopped by the hours, minutes and seconds without adding cumbersome easily read. Impeccable operation even when diving at a depth of 1,000 metres (100 bar). Concerning the operation of the chronograph function, Sinn have the same in many respects developed even more future-oriented standards. Because the chronograph can be stopped under water, and because of the large, non screw down pushers even with diving gloves use. Safe operation is ensured until nominal pressure is reached, a feature in addition to the bezel, offers the user and additional timing feature. The styling of the U1000 fulfils the strict standards applicable to mission timers. Among other things this means that form rigorously follows function. The ingenious dehumidifying technology guarantees protection against moisture. For every diver, knowing that their watch will not mist up is of life saving importance. Sinn have solved this problem with their patented, technologically sophisticated dehumidifying technology. To slow down the ageing of the oils caused by enclosed air humidity inside the watch, the U1000 mechanism is mounted in a dry atmosphere created by three supporting elements being the copper sulphate water absorbing capsule, double Viton seals and inert argon gas filling. German submarine steel guarantees seawater resistance. The U1000 casing is made of practically sea water resistant submarine steel and has been hardened using Tegiment technology. It offers effective protection against scratching of the casing surface. The watch has got a 60 minute, 60 step ratcheted rotating bezel which is also secured against inadvertent adjustment by patented system, for example when receiving a bump. The watch is guaranteed to operate between - 45°C to + 80°C. In summary, the features are as follows: Full Tegiment construction - six times harder than standard steel watches. Case constructed of submarine steel for superior resistance to corrosion, scratches and magnetism. Double Viton® seals. Modified SZ-02 movement with redesigned 60 minute register. Sinn special oil for operation in extreme temperatures. Four Sinn copper sulphate capsules to absorb moisture and humidity.
