Quick TakeThe Sinn UX S is a beast of a watch, a tool built to handle practically anything. The submarine steel, blacked-out and Tegiment-hardened, says, "Bring it on," to the most brutal conditions. The oil-filled case is where this diver separates its self, it's like staring into the pure, unadulterated black of a digital screen, no reflections, no distortion, just stark white indices and hands, and that signature red seconds hand, popping with mission-timer clarity. GSG 9's choice, rated to an insane 5000m – this isn't about style points. This is a high performing instrament. With its 44mm size, it makes its presence known, and the quartz movement means it's always ready. The UX S isn't just a watch; it’s a statement.

DescriptionThe Sinn 403.060, designated UX S (EZM 2B), represents a specialized timepiece engineered for professional maritime use, officially adopted by the maritime squad of the GSG 9 Special Forces unit. Its construction begins with a 44mm case meticulously crafted from high-strength, seawater-resistant German submarine steel, ensuring exceptional durability and corrosion resistance. This robust case houses a high-precision, temperature-stabilized ETA 955.652 quartz movement. This movement features seven bearing jewels, a seconds stop function for precise time setting, and is shock-resistant as per DIN ISO 1413 and anti-magnetic in accordance with DIN 8309. The case thickness measures 13.3mm, with a lug width of 22mm accommodating the integrated bead-blasted solid stainless steel bracelet, which also features a black hard coating. The movement operates reliably in extreme temperature conditions, ranging from –20 °C to +60 °C, because of Sinn's Temperature Resistance Technology.

The watch is engineered around Sinn's proprietary HYDRO Technology. This involves filling the case with a specialized oil. The oil serves multiple functions: it renders the watch completely free from fogging, eliminates underwater reflection, and grants the user unparalleled readability from any viewing angle. Additionally, the oil filling allows the case to withstand pressure equivalent to 5000m diving depth (500 bar), independently certified. The case incorporates a screw-fastened case back and a screwable crown positioned at 4 o'clock, designed to prevent pressure against the back of the hand. The dial is protected by sapphire crystal glass, treated with an anti-reflective coating on both sides to minimize glare. The watch is tested and certified to the European diving equipment standards EN 250 / EN14143. In terms of resistance, the watch is low pressure. It also meets the technical standards for water resistance as detailed in DIN 8310 and is tested for the diving norm, DIN 8306.
