SINN U15 Limited Edition
SINN presents U15, a limited edition diving watch made with a high-strength, seawater-resistant German Submarine Steel from the decommissioned U 15 submarine.
Commissioned in 1974, German submarine U15 (S-194) achieved an impressive record: 200,045 nautical miles, meticulously documented by a former crew member. After its decommissioning, Sinn Spezialuhren acquired material from the submarine’s outer hull, using it to craft a limited-edition diving watch.
Limited to 1,000 pieces, SINN U15 has a robust case made from high-strength, seawater-resistant steel sourced directly from the U 15 submarine.
Sinn Spezialuhren has a special, long-standing relationship with submarines. The company has been using submarine steel for its diving watches for two decades – convinced by its exceptional performance.
The special grade of steel developed by ThyssenKrupp for the outer hulls of the Type 206 submarine and the world’s latest non-nuclear Type 212 submarines has formed the basis of all of the SINN U series since 2005. It is supplied as a semi-finished product with the required dimensions and structural properties and is therefore free of any signs of use.
The steel of Model U15 sets itself apart in one key aspect: this base material had previously clocked up decades of naval use. The professional, meticulously intricate finishing by the Saxony-based watchmaking technology company Sächsische Uhrentechnologie GmbH Glashütte (SUG) ensures that it meets SINN’s stringent requirements without losing its true identity. Adding to this experience is an engraved steel blank from the original submarine U 15, included with the watch.
The U15´s anti-reflective sapphire crystal guarantees exceptional clarity and provides an optimal view of the high-gloss dial, which echoes the mesmerising blue nuances of the ocean.
The dark bluish green base tone portrays the esoteric expanse of the open sea from a depth of around thirty metres, alluding to the operating range of the U 15 submarine, which was able to dive to depths of up to 100 metres.
Stylised air bubbles that symbolise the rising air bubbles underscore the three dimensional effect with metallic blues and greens. This variance brings a unique touch to the dial and catches the eye with an intriguing stereoscopic effect. As a historical memoir of the power of submarines, the dial features the number of nautical miles travelled and the U 15´s type designation. The case back is adorned with a matching silhouette of the Type 206 submarine.
The U15 has been tested according to European diving equipment standards and certified by an independent institute, ensuring its durability and reliability.
