Description

The SDR version of Sinns U1 features a bezel with Black Hard Coating on a TEGIMENT Technology basis., , With the diving watch U1, Sinn engineers succeeded in developing a diving watch in which the quality of material and design gives it superior resistance to external influences under extreme conditions of use., In their search for a steel with the desired resistance, the Sinn engineers found what they were looking for at the German submarine manufacturer ThyssenKrupp Marine Systems: the steel manufacturers supply small quantities of the original steel of the current German submarine production exclusively to Sinn for making diving watches — the very steel of which the external hulls of the German Navys new submarine class 212, which currently represents the most advanced non-nuclear submarines in the world, are made. This original submarine steel is not only extraordinarily seawater-resistant but is also of the highest non-magnetic quality without any residual magnetism., , To ensure reliably that the rotating bezel of the diving watch does not detach under harsh impacts, it is attached as a captive bezel to the central part of the case. The ratcheting is mounted on a sophisticated bearing system. Slightly radially offset locking pin positions protect the toothed ring, ensure reliable function over the long term and facilitate firm and secure ratcheting with a rich clicking sound., , The water-resistance and pressure resistance of 100 bar (= 1000 m water depth) was certified for the diving watch U1 by DNV GL. The safety test pressure used for this purpose was 125 bar., , As per unknown date this watch is powered by a Sellita movement instead of ETA.
