This is an awesome German dive watch from Sinn(the S is pronounced as a Z). Sinn is a German company. It was founded by Helmut Sinn in 1961, a World War 2 pilot and watch enthusit.

Sinn has quite the following of loyal fans and enthusiasts alike. I personally think the Sinn U2 is their best diver. I am trying to do a hands on review so be sure to check back here for that. I love the dial layout for his watch. What I also love about this watch is how rugged it is. It’s made from the same steel that used in submarines, highly resistive to salt water corrosion. Check out the technical data below. Forget the Rolex James Bond, this is the watch you should be wearing.(check out this link for more on that:  http://www.woundforlife.com/2014/05/12/opinion-ultimate-james-bond-watch/)

Thanks to Kleiter Sabine from Sinn Watches for sending me the pictures and information. Sinn may be a small company but they make awesome, high quality watches and have sone of the best customer service out there!

The diving watch U2 is a professional mission timer which uses genuine German submarine steel, a material with extreme seawater-resistance and the highest level of non-magnetic properties. Sinn’s special oil and an adjusted position tolerance of the parts in the diving watch U2 series guarantee operation at temperatures ranging from minus 45 °C to plus 80 °C.
And that’s not all: with the diver’s bezel, this diving watch is well-equipped to measure the duration of a dive accurately. Fogging of the dial poses a safety risk when diving. To prevent this, we use EDR seals. This material, with its extreme chemical resistance and only a quarter of the gas permeability of conventional seals, prevents moisture from diffusing into the diving watch. The slightly domed, 4.2 mm thick scratch-resistance anti-reflective sapphire crystal glass withstands even the highest pressures. The case is filled with a protective gas, while three drying capsules keep the interior dry.
