Sinn - UX SDR GSG 9

Rescuing the hijacked “Landshut” aircraft on October 18, 1977 in Mogadishu made the German GSG 9 (Grenzschutzgruppe 9) special forces world-famous. Just as legendary as the reputation of the anti-terrorism unit of the German federal police is the diving watch that their maritime unit wears during its missions.

Together with GSG 9, we developed the EZM 2 mission timer in the mid-1990s. This timepiece met the special functional requirements of the divers exactly and incorporated the successful features of the 403 HYDRO diving watch. Now this service watch has a worthy successor that can be purchased by anyone: the UX GSG 9 (EZM 2B) diving watch.

The diving watch incorporates proven features such as the HYDRO Technology for perfect readability even under water and freedom from reflection at any angle, a large black dial with white hands and 5-minute indices, especially visible at 12 o'clock (mission timer design), a case made of seawater-resistant submarine steel and a captive diver's bezel with TEGIMENT Technology. The position of the crown at 10 o'clock to prevent pressure on the back of the hand is a feature, as is the "GSG 9" logo on the dial.
