Product Details 

The Sinn 756 UTC Black capitalizes on all that's great with the standard Sinn 756 UTC, but adds a black case created with Tegiment PVD technology.

Normally, watch cases with applied PVD are subject to increased risk of cracking because of the difference in hardness between the base metal and the PVD (eggshell effect). At Sinn, technology again has been used to not only solve a problem but to enhance a watch.

This watch features "Tegiment" technology. Standard steel used by most watch companies has a hardness of between 200 and 240 HV (Hardness Vickers is a common scale used to measure material hardness). The Tegiment layer has a hardness of 1,200 Vickers which is up to five times harder than standard steel.

The Tegiment layer is not a coating consisting of a foreign material, instead the steel itself that has been hardened using a special engineering process that creates a hardened barrier. The base material is a type of stainless steel also used for surgical implants, and the stainless steel resistance to corrosion is even further improved by the Tegiment hardening process.

Next, this case offers magnetic field protection of up to 80,000 A/m, among the highest for any mechanical watch. The case back is nickel free offering protection to those with allergic reactions to this metal.

The second time zone is displayed by an outlined yellow sweep hand. The case features a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the watch.

Sand-blasted stainless steel case with black Tegiment PVD technology and solid back. Dial is matte black with Arabic numerals and offset date display at 4. The design and layout of this watch make it extremely easy to read in virtually all light conditions.

Sapphire crystal with luminous hands and hour markers. Watch is water resistant to 20 ATM.

Warranty Changes and New Features

Please note that effective September 1, 2011 Sinn increased the warranty on this watch from 2 years to 3 years. Watches purchased before that date remain at 2 years.

The reason for this change is that Sinn is now adding their Dehumidifcation Technology to this watch through the use of inert gas to reduce humidity inside the case and to prevent the dial from fogging.
