The mission timer for maritime use 
Developed to withstand extreme situations in which absolute precision and reliability are crucial. A UX unites the most innovative technologies with the most resistant materials. Typical diving watches by Sinn.
• UX GSG 9 (EZM 2B): Crown at left at 10 o'clock. Official service watch of the GSG 9 Maritime Unit
- Tested based on European diving equipment standards and certified by Germanischer Lloyd, Hamburg
- Pressure resistance of the movement to 5,000 m and of the case to 12,000 m diving depth has been tested and certified
- Reflection-free under water thanks to HYDRO technology, readable from any angle and completely free from fogging
- Completely seawater-resistant to German submarine steel
- Captive diver's bezel with TEGIMENT technology
- Sapphire crystal glass with anti-reflective coating
-Temperature-stabilized chronometer quartz movement, functions reliably at temperatures between –20 °C and +60 °C
