Sinn U1 Divers Watch Tegiment

$4,970.00 CAD

Shown here is the U1 diving watch with the Tegiment option on an H-link bracelet. 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 Navy's 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 water-resistance and pressure resistance of 100 bar (= 1000 m water depth) was certified for the diving watch U1 by DNV. The safety test pressure used for this purpose was 125 bar.

Special Characteristics:

  • TEGIMENT option:
    The case also features TEGIMENT Technology, making it especially scratch-resistant. If you choose a silicone strap, the design of the clasp will also be on a TEGIMENT Technology basis. If you decide to go for a solid bracelet, this also features TEGIMENT Technology.

  • Case and crown made of high-strength, seawater-resistant German Submarine Steel
  • Case and bezel with TEGIMENT Technology and therefore especially scratch-resistant
  • Diameter of case: 44 mm
  • Tested based on European diving equipment standards and certified by DNV
  • Captive diver's bezel with minute ratcheting
  • Crown at 4 o'clock to prevent pressure on the back of the hand
  • Sapphire crystal glass
  • Waterproof and pressure-resistant to 1,000 m diving depth (= 100 bar), certified by DNV
  • Low pressure resistant
