Sinn U1 B Tegiment Special Edition


Model: 1010.0102 Tegiment

The Diving Watch made of German Submarine Steel with blue dial.

  • Blue electroplated dial
  • Case and crown made of high-strength seawater-resistant German Submarine Steel
  • Tested based on European diving equipment standards and certified by DNV GL
  • Pressure-resistant to 1,000 m diving depth (100 bar), certified by DNV GL
  • Captive diver’s bezel with minute ratcheting
  • Bezel with TEGIMENT Technology and therefore especially scratch-resistant
  • Sapphire crystal glass
  • Resistant to low pressure

Striking lines, minimalistic displays and clear readability define the diving watches in the U1 series. A special feature of the U1 B is the blue electroplated dial.

The luminous white indices and hands provide a strong contrast to the blue dial, ensuring outstanding readability at all times. The distinctive colours of the U1 B are further emphasised by a blue silicone strap.

The case made of high-strength German Submarine Steel is extremely seawater-resistant and also possesses the highest level of non-magnetic properties. Hardened using TEGIMENT Technology and therefore especially scratch-resistant, the captive diver’s bezel with minute ratcheting is virtually impossible to detach by being knocked off.

DNV GL verifies and certifies the pressure resistance of the U1 B to a diving depth of 1,000 metres and its temperature resistance and functionality in accordance with the European diving device standards. Users of the U1 B can thus be assured that they are wearing a precise and reliable diving watch on their wrist.

U1 B TEGIMENT – Special series for Define Watches

Sinn’s U1 B is a robust timepiece featuring a case of submarine steel and a Tegimented bezel but even so, we have a tougher version for those who need a little more.

The U1 B Tegiment version has all the features of the standard U1 plus the additional upgrade of a fully Tegimented steel case, making it a watch that can withstand a lot!

Combine the Tegi case with your choice of band to complete the look and functionality.

A variety of leather band options are available for everyday wear and, if you need something a bit more water resistant, why not select one of Sinn’s outstanding silicon bands (fitted with a fully Tegimented diver’s clasp to match the case) or upgrade to a massive Tegimented steel bracelet for optimum comfort.
