207,000 nautical miles in 38 years – a proud legacy
Commissioned in 1973, submarine U 16 achieved an impressive record: 207,000 nautical miles, meticulously documented by a former crew member. This astonishing figure equals about ten journeys around the globe! After its decommissioning, Sinn Spezialuhren acquired material from the submarine’s outer hull, using it to craft the heart of a unique, limited-edition diving watch. Limited to 1,000 pieces, the watch case is made from high-strength, seawater-resistant steel sourced directly from the U 16 submarine. This makes the submarine not only the namesake of model U16 but also an exclusive material source—and a timeless link to an unforgettable era in German submarine history.
Anniversary: 20 years of diving watches made of submarine steel
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 our 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.
Maritime history on your wrist
The steel of model U18 sets itself apart in one key aspect: this base material had previously clocked up decades of naval use, and that’s what makes it so special! The professional, meticulously intricate finishing by the Saxony-based watchmaking technology company Sächsische Uhrentechnologie GmbH Glashütte (SUG) ensures that it meets our stringent requirements without losing its true identity. The result? A diving watch forged from history, bringing the very soul of naval history to the wrist. Adding to this experience is an engraved steel blank from the original submarine U 16, included with the watch.
All eyes on the high-gloss dial
The U18´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 16 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 16´s type designation. The case back is adorned with a matching silhouette of the Type 206 submarine. The U16 has been tested according to European diving equipment standards and certified by an independent institute, ensuring its durability and reliability.

Additional Product Details
Sinn Watches was formed in 1961 by the legendary pilot and flight instructor Helmut Sinn. They began manufacturing flight watches based on his extensive aviation experience, this was primarily based on Mr. Sinn's dissatisfaction with the watches that were available for pilot and navigational purposes at that time. His own designs incorporated the features and functionality that he felt more fit for purpose as an instrument watch. This is a design philosophy that has transcended the company's culture right through to the present day. Sinn is now the world's most eminent manufacturer of high quality, precision, functional and purposeful instrument watches. From the beginning, their emphasis was on creating special purpose instruments that performed under extremely adverse operating conditions such as high speed, high and low pressures and altitudes, intense heat or pressure, extreme cold, high magnetic interference, and submergence in liquids. Sinn are becoming increasingly known for their instrument watches, and are today a force to be reckoned with as they lead the way in instrument watch design. The company changed hands in 1994 when Lothar Schmidt formerly of IWC assumed control and further expanded the boundaries of Sinn’s high tolerance manufacturing expertise. Over the past decade, Sinn has pioneered some innovative new technologies, including oil filled watch chambers to enable operation under extreme pressures, argon gas filled watches to prevent moisture infiltration, impact resistant gear suspensions, and new micro-lubricating techniques. Their timepieces are standard equipment in some of the most dangerous and adverse environments on earth - little surprise their watches are issued to the German military and elite forces. Above all the watches are manufactured and marketed to the world at large. Like the designs and their application areas, the pricing of the Sinn watches is most aggressive, making them available to most people. Due to distribution agreements Sinn watches can only be shipped to the UK and Ireland and certain countries where there is no Sinn agent assigned to that territory. Sinn watches are covered by a two or three year manufacturers warranty depending on the model.
