Sinn UX S Special Forces


Sinn UX S Special Forces
Model: 403.062

The diving watches of the UX (EZM 2 B) model series are the official timepieces worn by the maritime squad of the GSG 9 Special Forces unit. One of the outstanding characteristics of this series of watches, and therefore also of the UX S GSG 9, is Sinn’s HYDRO Technology. Sinn fill their watches with special HYDRO oil that makes them non-reflective underwater and completely free from fogging, and also ensures that the dial can be read from any angle. And because it is filled with oil, the case made of seawater-resistant submarine steel can withstand water pressure at every reachable depth.

Sinn have also treated the cases of these timepieces with their patented TEGIMENT Technology for additional robustness. Besides enhancing hardness, this treatment enables them to apply a high-quality, black PVD coating. 
The combination of these two techniques makes this diving watch perfectly suited for everyday use. Adding a coating with a hardness of 2000 HV (Vickers hardness) to the tempered steel (1500 HV) prevents the flaking that colored coatings are generally susceptible to.

This particular model bears the GSG9 insignia on the dial as a point of difference and acknowledgement.

In conjunction with its instrument chronographs and watches, Sinn is renowned for its sports and diving watches. Sinn diving watches have lead the way in terms of technical advances for timepieces that must withstand rough and demanding conditions. Thanks to its HYDRO technology, Sinn produces anti-reflective diver’s watches that are totally condensation-free, made of stainless steel and capable of reaching any possible diving depth. The HYDRO technology involves filling the watch case with a crystal clear oil that ensures the dial is legible from all angles, does not condense, and will not compress thus allowing it to withstand great water pressure from the outside. Other special features of Sinn water watches include:

  • Gaskets made of highly elastic plastic that remain water tight regardless of pressure
  • Scratch proof sapphire crystal, anti-reflective on both sides to ensure a clear view of the dial at all times
  • Luminous numerals, coated with a special inactive, long-lasting luminous paint
  • Magnetic field protection
  • Adjustable bands (stainless steel, titanium, silicone or shark skin) to allow the watch to be worn over a wet or dry suit.

Sinn sport and diver’s watches surpass standard DIN norms for diving watches. In fact, they fulfil the prerequisites of DIN 8306 in which strict safety standards for diver’s watches are precisely and extensively established. Anyone serious about diving or extreme watersports should have the reliability and performance of a Sinn sport or diver’s watch by their side.
