Quick TakeThe U50 HYDRO is more than a mere tool; it’s a statement of intent, a testament to Sinn's relentless pursuit of functionality. The German Submarine Steel case whispers of deep-sea adventures, resilient and unwavering. Feel the click of the TEGIMENT-hardened bezel, precise and assuring. Glance at the dial, crystal clear even through the abyssal depths. HYDRO Technology transforms the mundane act of reading time underwater into an experience devoid of distortion. This isn't just about surviving 5000 meters; it's about thriving there, with every detail finely tuned. The quartz movement’s accuracy is a reassuring pulse, reliable across drastic temperature fluctuations, a testament to its quality build. The 4 o'clock crown hints at its consideration for the wearer, a subtle design choice. This is the U50 HYDRO, an ally for those who dive headfirst into the unknown.

DescriptionThe Sinn U50 HYDRO, reference 1051.010, represents a significant achievement in dive watch engineering. Its 41mm case, crafted from bead-blasted, high-strength, seawater-resistant German Submarine Steel, provides exceptional durability and anti-magnetic properties per DIN 8309. The screw-fastened case back and screwable crown, positioned at 4 o'clock to avoid discomfort, contribute to the watch's remarkable water resistance. This model is certified by an independent institute to withstand pressures equivalent to a diving depth of 5000 meters (500 bar) and meets the water-resistance criteria outlined in DIN 8310. It also adheres to the technical requirements of diving norm DIN 8306, further verified through testing based on European diving equipment standards EN 250 and EN14143. The total weight, sans strap, comes in at 72 grams.

Powering the U50 HYDRO is a Swiss-made Ronda 715 Li quartz movement, selected specifically for its compatibility with Sinn's HYDRO Technology. This technology involves filling the case with oil, which eliminates internal reflections and ensures absolute freedom from fogging. The Ronda 715 Li, equipped with five bearing jewels, features a long-lasting lithium battery. Operational reliability is confirmed between -20°C and +60°C. An End-of-Life (EOL) function provides advance warning of battery depletion. The matte black dial features indices, hour, minute, and second hands all coated with luminescent material for enhanced visibility. A date display is integrated. Protecting the dial is a sapphire crystal, anti-reflective on both sides. The captive diver's bezel, with minute ratcheting, is treated with Sinn's TEGIMENT Technology, hardening the surface for exceptional scratch resistance. The band lug width for fitting is 20mm, while the case diameter is 41mm, case thickness is 11.8mm.
