Sinn U50 HYDRO S 5000m (41mm) Black Dial / Grey Silicone Strap

The Sinn U50 Collection is a family of diver’s watches, precisely engineered for water-based activity. The case of each watch is made of high-strength German Dubmarine Steel to ensure the watches are seawater-resistant, making them suitable for diving. The U50 watches are tested based on European diving equipment standards to ensure they are functional and reliable up to 500m of diving depth (50 bar). Sinn is known for pushing their watches to the absolute limits, and this watch is no exception. With numerous Sinn technologies and automatic movements, the U50 watches are long-lasting and dependable diver’s watches.

Core Features of the U50 Collection: 

• All of the watches in Sinn’s U50 Collection have a case made of high-strength, seawater-resistant German Submarine Steel.
• The captive diver’s bezel of each watch is treated with TEGIMENT Technology, making it scratch-resistant. This ensures they can withstand the rigorous use that a diving watch goes through. The bezels all feature minute ratcheting and a luminous key mark. 
• The crown of each of the watches is placed at the 4 o’clock position so that it does not put pressure on the back of the hand. 
• The dial of all of the U50’s is protected by sapphire glass with anti-reflective treatment on both sides. 
• The waterproofing is aided by the screw-fastened case back and screwable crown. All of the watches meet the technical requirements for waterproofness, as set out in standard DIN 8310 and according to the technical demands for the diving norm DIN 8306. The watches are tested based on European diving equipment standards EN 250/EN 14143. They are also resistant to low pressure. 
• Each of the watches in the collection has a case diameter of 41mm, a band lug width of 20mm and a case thickness of 11.15mm. They all weigh 74 grams without a strap.
