SINN Diving Watch Collection : Models U1000, U1000 S and U1000 SDR

SINN was the first company to manufacture diving watches that complied with European diving equipment standards, and the first to test and certify them for pressure resistance, water-tightness and resistance to fogging. The technical development of diving watches is one of the greatest challenges for engineers and watchmakers, because these timepieces must be absolutely waterproof, perfectly readable in all lighting and water conditions and extremely durable. Sinn watches are the ideal mission timers.

Models U1000, U1000 S, U1000 SDR
A diver needs equipment that is 100% reliable. SINN manufactures watches that meet the toughest safety standards for use at great depths. From certified materials to SINN’s own proprietary technologies, its watches offer everything divers need.

  • Tested based on European diving equipment standards.
  • Pressure-resistant to 1,000 m diving depth
  • Made of completely seawater-resistant German submarine steel
  • Captive diver’s bezel with guard against unintended displacement
  • Sapphire crystal glass with anti-reflective coating
  • dehumidifying technology for enhanced freedom from fogging
  • Functions reliably at temperatures between –45 ºC and +80 ºC thanks to SINN Special Oil 66-228
  • Chronograph functions can be actuated up to the nominal pressure (100 bar) even when wearing diving gloves

Model Variations
