Sinn U50 SDR Steel Watch

The Watch

Founded in 1961 in Frankfurt am Main, Sinn is a German brand that has made its mark with unique, high-performance timepieces. Its models are known for their robustness and functionality, with several innovations to its name - including the first automatic watch sent into space. Sinn watches are the result of unparalleled expertise combining cutting-edge technology, Swiss mechanics, and exceptional performance. Today, the brand is proud to introduce the stunning U50 SDR Steel, a limited edition that will captivate passionate fans of the seas and oceans. Its round case is crafted from German submarine steel - sourced from the naval construction company ThyssenKrupp Marine Systems - prized for its extreme resistance to seawater and its amagnetic properties. Its micro-blasted finish adds unmistakable character. The case measures 41 mm in diameter, 11.20 mm thick, weighs 74 g, and is designed for men's wrists. The special captive bezel is also machined from a piece of submarine steel and features a luminescent triangular marker. Unidirectional with a sandblasted finish, it features a minute track for measuring dive time. Its black scratch-resistant coating and Tegiment treatment deliver outstanding resistance to scratches. The dial is protected by a flat sapphire crystal, shielding it from shocks and everyday wear. It benefits from anti-reflective treatment on both sides for optimal legibility of the central indicators. These are adjusted via the substantial knurled crown, which offers easy handling during setting. It is screwed down at 4 o'clock to prevent any friction against the wrist. Finally, the screwed case back guarantees water resistance of 50 ATM.

The Dial

The stunning round, black dial of this model enhances its elegance, blending unique design, functionality, and performance. Its matte background is complemented by color-accented indicators for perfect legibility. Two rectangular hands in red and white sweep its center to mark the hours and minutes, accompanied by a red seconds hand. Together, they point to twelve rectangular indexes that mark the hours. All indicators are coated with a luminescent treatment for legibility even in low light. A fine minute track runs along the perimeter for added precision. A discreet black date window at 3 o'clock displays the date. Finally, the brand places its signature at 12 o'clock.

The Movement

This exceptional timepiece is powered by a Swiss-made automatic movement - the Sellita caliber SW 300-1, which drives the hands and date window with precision. It beats at a frequency of 28,800 vph and features 25 jewels. Its power reserve is 38 hours. The movement incorporates a stop-seconds function and offers protection against magnetic fields in accordance with DIN 8309 standard.

The Bracelet

This stunning watch comes paired with a bracelet crafted from German submarine steel, elevated by a micro-blasted finish. Its links lend it a sophisticated yet sporty look. Durable and comfortable, it complements any outfit and adds an elegant touch to your style. The lug width measures 20 mm, and it fastens with a deployant clasp.

Water Resistance

This model offers water resistance of 50 atmospheres, or 500 meters. Whether you're playing 20,000 leagues under the sea in the pool with your kids or tackling serious deep-sea diving with tanks, this watch has you covered. The depths and all their creatures don't stand a chance - you're ready. The Ocarat team wishes you a great underwater adventure, with one final tip: don't operate the push buttons or crown on the way down!
