Quick TakeThe Sinn UX SDR GSG 9 isn't just a watch; it's a testament to German engineering and the spirit of elite tactical operations. Developed in collaboration with the legendary GSG 9, this timepiece speaks volumes of resilience and precision. The submarine steel case, fortified with TEGIMENT technology, stands as a resolute guard against the harshest environments. Its HYDRO technology makes the dial legible underwater, while that, paired with the bold, mission-timer design, reflects a purpose-built aesthetic. The offset crown hints at its ergonomic consideration for comfort during extended wear, whether a wet suit is worn or not. It’s a watch that looks cool, and can handle extreme pressure and temperatures, while being precise. The GSG 9 logo isn't just a branding element; it’s a symbol of its proven pedigree. The UX SDR GSG 9 embodies a functional, no-nonsense tool, conceived to withstand the rigors of professional use while retaining an understated, formidable presence.

DescriptionThe Sinn 403.081, also recognized as the UX SDR GSG 9 (EZM 2B), represents a high-performance diving instrument, purposefully engineered for extreme operational conditions. It benefits from considerable input during development, with the GSG 9, the German federal police's anti-terrorism unit contributing. This design collaboration is directly reflected in critical characteristics like optimal readability. The 44mm case is manufactured from bead-blasted, high-strength German Submarine Steel, providing exceptional resistance to the corrosive effects of seawater. The incorporation of TEGIMENT Technology significantly enhances the case's surface hardness, making it exceptionally scratch-resistant. The case back is securely screw-fastened, and the crown is screwable, conforming to the technical prerequisites for water resistance, outlined in standard DIN 8310.

This timepiece is certified by an independent institute, for water and pressure resistance to a diving depth of 5000 meters (500 bar) and is tested in compliance with European diving equipment standards EN 250 and EN14143, along with the diving norm DIN 8306. The model is also low-pressure resistant. It operates by utilizing a high-precision, temperature-stabilized ETA 955.652 quartz movement, which has seven bearing jewels and a seconds stop function. It maintains anti-magnetic capabilities according to DIN 8309 standards. The watch incorporates Sinn's HYDRO Technology; this ensures exceptional readability underwater, eliminating reflections at any viewing angle and preventing fogging. Functional reliability is guaranteed within a temperature range of –20 °C to +60 °C, due to built-in temperature resistance technology. A captive diver’s bezel with minute ratcheting is included, featuring a Black Hard Coating on a TEGIMENT Technology basis. The matte black dial has indices, and hour, minute, and second hands are coated with luminescent material for optimal readability.
