Quick TakeThe U50 is the embodiment of functional, no-nonsense design—a tool watch through and through. Its German Submarine Steel case whispers resilience. The stark, matte black dial, punctuated by luminescent indices and hands, is all about at-a-glance legibility. This isn't a watch that begs for attention; it earns respect. That 500-meter depth rating, certified by DNV, isn’t just a number, it’s a genuine commitment, which gives you that knowledge that it is an instrument of confidence. The TEGIMENT-hardened bezel clicks with reassuring precision, a testament to SINN’s engineering focus. Every element of the U50, from the perfectly placed 4 o'clock crown to the smooth sweep of the SW300-1 movement, speaks of purpose. It's a watch for those who appreciate robust engineering, understated aesthetics, and the quiet confidence of a tool built to perform under pressure. The perfect dive watch.

DescriptionThe Sinn U50, reference 1050.010, is a purpose-built diving instrument engineered for professional use and resilience. Its core construction centers around a 41mm diameter case meticulously fashioned from bead-blasted German Submarine Steel. This specific steel alloy is chosen for its impressive strength, exceptional resistance to the corrosive effects of seawater, and its non-magnetic qualities, conforming to DIN 8309 anti-magnetic standards. The case back is securely screw-fastened, enhancing the watch's overall structural integrity. A screwable crown, strategically positioned at the 4 o'clock location, prevents discomfort or pressure against the wearer’s hand during underwater activities. The watch achieves water and pressure resistance to a depth of 500 meters (equivalent to 50 bar), a rating rigorously verified and certified by DNV, an independent testing organization. Its construction and functionality are tested based on the European diving equipment standards EN 250 and EN14143, also confirmed by DNV, and it also adheres to the diving norm DIN 8306 while remaining low-pressure resistant.

Powering the U50 is the SW300-1 self-winding mechanical movement. This movement incorporates 25 bearing jewels to minimize friction and wear, promoting accuracy and longevity. It oscillates at a frequency of 28,800 semi-oscillations per hour, and it incorporates a seconds stop function, allowing for precise time setting. The dial, finished in a matte black, provides maximum legibility, further enhanced by indices and hour, minute, and second hands coated with a luminescent material for optimal visibility in low-light conditions. The watch features a date display. Integrated into the design is a diver’s bezel with precise minute ratcheting. This unidirectional bezel, designed to be captive within the case structure, incorporates SINN's TEGIMENT Technology, vastly increasing its surface hardness and scratch resistance. It features a noticeable luminous key mark. The watch face is protected by sapphire crystal glass, treated with an anti-reflective coating on both internal and external surfaces to minimize glare. The band lug width measures 20mm. Total case thickness is specified as 11.2mm, with the watch weighing 74 grams without the included bead-blasted solid stainless-steel bracelet.
