One of the most popular Sinn limited edition watches in the last few years was a fully Tegimented, all black PVD version of the Sinn U212, with the official title Sinn U212 SE.

We remember the watch well, as it was a knockout in person and one that we continually pestered Sinn for additional pieces since our initial allocation sold out in the first two days.

The only criticism of the Sinn U212 SE was that for some people it was too big as it featured a 47 mm case.

Sinn has responded to the many requests to create a watch drawing inspiration from that original design but in a smaller case size of 44 mm with the Sinn U1 SE black with a fully Tegimented case on a fully Tegimented bracelet.

The Sinn U1 Series has become the best selling in the brand’s history and is recognized as iconic to the brand.

The Sinn U1 SE changes the original design of the classic Sinn U1 by adding a fully Tegimented PVD black case and a new dial, bezel and hands, which like the Sinn U212 SE feature SuperLuminova in an ivory color.

The result is a watch that is a bit more subtle in design as the watch uses no red as in the standard Sinn U1.

The Sinn U1 SE on black bracelet features the same great case design made in-house from German submarine steel at Sinn’s case making facility in Glashutte, Germany. Once the case is complete, the Tegimenting process begins, and when we say “fully Tegimented” we mean what we say – case, crown, bezel, case back and even the anti-reflective coating.

The combination of the submarine steel and fully Tegimented case create superior scratch and corrosion resistance.  

And unlike watches made in stainless steel, this watch case does not need to be rinsed with tap water with each exposure to a salt water environment since it is made from true submarine steel.

The uni-directional ratchet operated rotating bezel is also milled from this submarine steel and is Tegimented. The indices are machined directly into the bezel without the use of bezel inserts, which can corrode or come loose at deep depths. 

The international testing lab of Germanischen Lloyd has tested the Sinn U1 SE on bracelet, and determined that the watch can be certified as water resistant to 1,000 meters. This same firm tests submarines for their ability to withstand the effects of underwater use.

Matte black dial with date at 3, ivory SuperLuminova on hands and markers, and the same ivory color is carried over to the bezel.
