German watchmaker Sinn has released a new series of diving watches based on the popular U1 diver. Unlike the Sinn U1 (44m), the new U50 series is presented in a more wearable 41 mm case width and three different references.
While U50 has a case, bezel, and crown made from Sinn’s characteristic bead-blasted seawater-resistant German submarine steel, the U50 SDR is differentiated by the presence of a bezel with a black hardening coating using Sinn’s proprietary Tegiment technology. The third model U50 S goes all black with a case, bezel, and crown all sheathed in the aforementioned black hardening coating.
All three models have the same case dimensions – the width is 41 mm and the thickness 11.5 mm. As mentioned earlier, the bead-blasted case gives it a modern tool watch appearance. The bezel again is a Sinn innovation – the Captive Safety bezel differs from that of conventional snap-in mechanisms. Its special design prevents the rotating bezel from accidentally being prised off the case. You have to push down on the bezel with two fingers in order to move the bezel. The case is topped by a sapphire crystal and is fitted with a screwed-in caseback.
Unlike the U1 diver, which is depth-rated to 1,000 meters, the U50 is water-resistant to 500 meters and complies with DNV-GL (A Norwegian-German classification) standards. The case also meets anti-magnetic standards prescribed by DIN (German National Standard) 6308. The Spartan black dial against has designed with clear legibility in mind. The blocky syringe-shaped hands and hour markers see the generous use of SuperLuminova.
The watch is powered by a Sellita SW300-1 movement, a 4 Hz movement with a power reserve of 38 hours. The models U50 and U50 SDR is presented in matching bead-blasted steel bracelets and rubber straps while the black U50 S model has a matching black bracelet and a choice of rubber straps. All three references come with a 2 year warranty. Prices start from $2,180.
