Sinn Releases U50 S BS Limited Edition Watch

A new expert dive watch has joined Sinn’s U50 dive watch series. The U50 S BS watch has been equipped with a 500-meter water-resistant case crafted from German Submarine steel and a captivating blue-black gradient dial

 

Sinn is perhaps most notably known for its expertly developed pilot’s chronograph watches, but what it also has a solid track record in is producing over-engineered, completely utilitarian and very German watches for diving. One of the best examples of such is the robust and dive-ready U1 watch – known for its use of German submarine steel. But the smaller version of this diving instrument is the U50 – a more compact dive watch with no compromises made to its original dive watch concept. This reduced Sinn U1 watch is designed with utmost performance and robustness in mind. The Sinn U50 is certified and approved as an official piece of European diving equipment and is appreciated amongst the diving community since its design has been tested by the likes of ISO and DIN. The new addition to the Sinn U50 dive watch line is the limited edition U50 S BS watch, exclusive to just 500 pieces worldwide. It comes in a stunning blue-black gradient dial for enhanced legibility, whilst the design of its case is prepared to face extreme conditions, both in and out of the water.

 

 

The purpose-built spirit of the Sinn U50 watch continues on from the U1 watch but comes in a much more manageable size for those who consider the original 44mm size of the U1 to be too hefty. This more compact 41mm model brings to the wrist a 500-meter water-resistant capability and comes equipped with all the advanced features of the U1 line, including the brand’s TEGIMENT technology with a black hard-coated treatment applied to its German submarine steel case.

 

A dive watch made from German submarine steel

 

The new 41mm Sinn U50 S BS watch is crafted from German submarine steel – a special grade of steel developed by ThyssenKrupp for Germany’s latest non-nuclear submarines. The material is 100% austenitic steel and is chosen for its superior strength. It also promises non-magnetic properties and a mechanical strength that is more than one and a half times greater than that of standard stainless steel AISI 316L. Most importantly though, German submarine steel is perfect for Sinn’s dive watches, since it has a unique resistance to saltwater. Whereas a normal steel watch should be rinsed with fresh water after diving into the sea (due to its long-term damaging corrosive effects), the German submarine steel used by Sinn’s diving watches can withstand prolonged contact with salt water, not to mention the material’s ductility and crack-resistant qualities.

 

Sinn’s TEGIMENT technology

 

Sinn’s TEGIMENT technology increase the case’s scratch resistance thanks to this special surface hardening. It raises the hardness of the watch’s base material significantly and was first showcased on the Sinn 756 Duochronograph watch at Baselworld in 2003. Since then, Sinn has improved this special technology. It can now harden all the case materials offered in Sinn’s catalogue as opposed to initially just the stainless steel models. In addition to its hardening quality, TEGIMENT technology also protects against scratching.

 

 

The new Sinn U50 S BS Limited Edition dive watch features a scratch-resistant and anti-reflective sapphire crystal glass front, as well as a screw-fastened caseback, a screwable crown, and is resistant to low pressure. The striking blue-black gradient dial of the new Sinn dive watch makes for an unusual but highly attractive choice. Its surface, with a vivid ocean blue centre, melds into a dark blue tone before reaching a black edge around the periphery of the dial. Here, the rectangular-shaped hour markers glow richly in the dark thanks to their luminous coatings. The dial also features matching luminous-treated central hour and minute hands, as well as a luminous tip on the central second hand. The U50 lettering is seen above the 6 o’clock locations, whilst a date window can be found at 3 o’clock. Surrounding the dial is a unidirectional rotating bezel in black. Its special captive design prevents the bezel from becoming detached from its black hard-coated case and features minute ratcheting for the successful measuring of elapsed time underwater.

 

 

Inside the case of the new limited-to-500-pieces Sinn U50 S BS watch is the Sellita SW300-1 – a tired and tested self-winding automatic movement that delivers a performance of 28,800 vibrations per hour. It also provides an impressive power reserve of 42 hours once fully wound and bears a total of 25 jewels – all of which are concealed behind the robust caseback of this advanced dive watch. The movement is also certified as magnetic resistant as per the standards outlined by DIN. To finish, the watch comes complete on a black hard-coated TEGIMENT treated German submarine steel bracelet with a folding clasp to secure comfortably to the wrist.
