Quick TakeThe U50 S is where robust engineering meets pure purpose. Forget delicate wrist candy; this is a serious instrument crafted from German Submarine Steel, finished with a hardened black coating. The captive bezel clicks with satisfying precision, a constant reminder of its 500-meter depth rating – certified, not just claimed. A matte black dial, designed with pure functionality in mind, keeps you focused on the essentials. A subtle date window. Hands glow with purpose. It's not about showing off; it is pure, unadulterated dive functionality. The SW300-1 automatic movement within offers dependability. It's the very definition of a tool watch; a piece of equipment not jewelery. 74 grams of serious purpose on your wrist, ready for anything from a desk to the deep, dark depths. It's a watch for people who go and do.

DescriptionThe Sinn U50 S, reference 1050.020, is engineered as a robust and highly legible diving instrument. Its construction centers around the utilization of high-strength, seawater-resistant German Submarine Steel, chosen specifically for its superior durability, exceptional non-magnetic qualities, and resistance to the corrosive effects of saltwater. The 41mm diameter case, along with the screw-down crown positioned at 4 o'clock, undergoes a Black Hard Coating applied over a TEGIMENT Technology base. This process significantly enhances scratch resistance, a vital attribute for a tool intended for demanding underwater use. The case back is securely screw-fastened.

Powering the U50 S is the SW300-1 self-winding mechanical movement. This caliber features 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour (4 Hz). It incorporates a seconds stop function (hacking) for precise time setting. The movement offers standard timekeeping functions: hours, minutes, and seconds, complemented by a date display integrated into the matte black dial. The watch's movement is anti-magnetic as per DIN 8309. The unidirectional diver's bezel, also constructed from German Submarine Steel with the Black Hard Coating on a TEGIMENT Technology basis, features a minute ratcheting mechanism and is designed to be captive within the case, preventing accidental detachment. The dial’s indices, as well as the hour, minute, and second hands, are coated with a luminescent material to ensure legibility in low-light conditions. A luminous key mark is also present on the diver's bezel. The watch face is protected by a sapphire crystal with anti-reflective treatment on both sides. The U50 S's performance adheres to rigorous standards. It meets the technical requirements for water resistance outlined in DIN 8310. Furthermore, its water resistance and pressure resistance to 500 meters (50 bar) is certified by DNV, alongside tests based on European diving equipment standards EN 250 and EN14143, again certified by DNV, and is also resistant to low pressure, making it a genuinely professional-grade dive watch. The band lug width measures 20mm. The watch head, without the strap, has a weight of 74 grams. Its total case thickness comes up to 11.2 mm.
