In 2015, Sinn has collaborated to celebrate the 35th anniversary from the Hour Glass, certainly one of Asia's leading replica watch retailers as well as Sinn's exclusive store within the South-East Asia region, the Sinn U1 Replica Watch. This is one of the most special U1 replica watches created by Sinn, featuring a camouflage dial inside a special edition of 500 pieces worldwide. The markings around the bezel in addition to areas of both your hands as well as the text from the replica watch are made inside a sandy hue and also the situation continues to be given a unique black coating to complement. The finish outcome is a wrist replica watch that appears as though it specified for particularly for troops operating in desert conditions. Actually, this is actually the first U1 to be carried out in a military-style.
The Sinn U1-D retains the 44mm dimensions of the standard U1, and also the use of special German submarine steel. According to Sinn, German submarine steel is highly resistant to seawater and also stronger, harder, and denser than regular stainless steel. This makes it ideal for diving. Speaking of which, the Sinn U1-D is water resistant to 1000m. It's case has been given a special Black Hard Coating. The coating is expertly applied and gives the case a uniform matte finish. Matte black dial with date at 3, Super Luminova on hands and markers, and striking red seconds hand complete the design. Other features include sapphire crystal with anti-reflective coating, and stainless steel bracelet.The special coating aside, the case has also been treated with Sinn's special Tegiment process. The U1 steel was procured by Sinn from a steel supplier to Emden GmbH which is one of Germans North Sea shipbuilding yards who construct submarines from the very same steel. This special steel is also amagnetic which means that is does not have magnetic properties and cannot itself become magnetized.
The uni-directional ratchet operated rotating bezel can also be milled out of this submarine steel and it is Tegimented. The indices are machined into the bezel without using bezel inserts, which could corrode or come loose at deep depths. The worldwide testing lab of Germanischen Lloyd has examined the U1, and figured that the timepiece could be licensed as water-resistant to at least one,000 meters. This same firm tests submarines for his or her capability to withstand the results of underwater use.
