Quick TakeThe U50 S L is more than just a robust dive watch; it's a beacon in the abyss. The German Submarine Steel case, cloaked in its Black Hard Coating, isn't merely tough; it's a silent dare to the crushing depths. Feel that TEGIMENT hardening, practically mocking scratches. The full-faced luminous dial is not some subtle glow; it is an act of rebellion against the dark, making the entire face blaze with intense light. Forget fumbling for a light switch; this is a miniature supernova on your wrist. That SW300-1 movement ticking inside isn't simply keeping time, it's measuring each passing moment with stoic, reliable precision. The U50 S L, at a precise 41mm size, clings to the wrist, with purpose. Limited to 500 pieces, it's a quiet assertion of capability. Certified to 500m, it is more than a promise; it's a DNV-verified handshake with the deep.

DescriptionThe Sinn U50 S L, reference 1050.0203, is a specialized diving instrument limited to 500 units. Its construction centers around a 41mm case made of high-strength, seawater-resistant German Submarine Steel, ensuring durability in marine environments. The case, along with the crown and captive diver's bezel, is treated with a Black Hard Coating applied on a TEGIMENT Technology basis. This hardening process is a critical feature and provides superior scratch resistance. The unidirectional bezel features minute ratcheting for accurate tracking of elapsed time. A screw-down crown, positioned at 4 o'clock, enhances wearing comfort by reducing potential pressure points on the wrist and, with the case back being screw fastened, contributes to a remarkable water resistance.

The movement chosen is the SW 300-1, a self-winding mechanism that features 25 bearing jewels and operates at a frequency of 28,800 semi-oscillations per hour. This movement includes a seconds stop function, facilitating precise time setting and is antimagnetic to the standards of DIN 8309. A defining component is the dial. A hybrid ceramic component, fully coated with luminous paint, is affixed to a metal base. The process ensures outstanding luminosity of the entire dial, making the whole display exceptionally legible under low-light conditions. Sapphire crystal glass, with anti-reflective treatment on both sides, protects the dial. The watch has a case thickness of 11.2mm, a band lug width of 20mm and, the weight of the watch case itself, not including any attachments, is 74 grams. DNV, an independent classification society, has certified the watch's pressure resistance to 50 bar (equivalent to a diving depth of 500 meters) and confirmed its temperature resistance and overall functionality are in accordance with European diving equipment standards EN 250 / EN14143, and with the diving norm DIN 8306. The product reference, 1050.0203, as noted in the description, is equipped from factory with a black silicone strap which is designed to seamlessly integrate with the watch case. It is paired to a sizable, folding clasp, constructed from bead-blasted stainless steel, itself receiving treatment with the aformentioned black hard coating.
