The D in the Sinn U1 replica dive watch’s name stands for Dune, which explains the watch’s color choices. The markings on the bezel as well as parts of the hands and also the text of the Sinn U1 swiss replica watch are rendered in a sandy hue and the case has been given a special black coating to match.
The Sinn U1-D replica dive watch 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 replica dive watch is water resistant to 1000m. Yet despite the high water resistance, it remains relatively thin, at around 14mm.
The Sinn U1-D replica dive watch’s case has also been given a special Black Hard Coating. The coating is expertly applied and gives the case a uniform matte finish. The special coating aside, the case has also been treated with Sinn’s special TEGIMENT process.
Like the standard U1, the Sinn U1-D replica dive watch has a flat sapphire crystal with anti-reflective coating on both sides. To match the blackened case, the dial of the Sinn U1-D replica dive watch is a shade of light grey with charcoaled indices, and text is printed in the same sandy brown hue as the markings on the bezel. The dial has a matte finish to it and doesn’t play much with the light, but under bright sunlight, it does change its tone a little and looks like its been bead-blasted. Finally, the hands are a mixture of sand brown and charcoal. The end result is a face that is similar in design to the standard U1, but distinctive enough to stand on its own.
