Product Details
|
To create this watch, Sinn built on the extremely popular design of the Sinn 857 UTC and added a black PVD Tegimented case.
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 on this watch has a hardness of 1,500 Vickers which is seven 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.
The Tegimenting process also acts as an extra protection for the black PVD coating by providing a harder surface for this material. It is interesting to note that Sinn's black PVD watches are hardened to higher standards than most of their non-black Tegimented watches.
The case back is nickel free, perfect for those with allergic reactions to case metals. Other features include protection from magnetic fields of up to 80,000 A/m, sapphire crystal with anti-reflective coating on both sides.
Another Sinn engineering feat is the creation of a bezel that is secured by screws. The inlaid aluminum ring featuring numerals and markers is anodized black for optimal legibility, while the triangle reference marker at 12 is applied with special paint for visibility.
The case features Sinn's Dehumidifcation Technology, which includes the use of inert gas in conjunction with a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the watch. This capsule may be viewed through a porthole in the left lug, and over time will turn a deep blue as humidity is absorbed. This technology not only provides a more stable environment for the movement, but also helps to prevent fogging of the crystal when going from hot to cold environments or from humid to non-humid conditions (such air conditioned buildings).
This watch has a second time zone displayed by a skeleton yellow tipped hour hand. The second time zone can be set directly through the second position of the crown and uses a 24 hour indication to differentiate AM and PM.
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, hour markers and the 12. Watch is water resistant to 20 ATM. Watch is fitted with a Sinn calf leather strap and tang buckle.
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 and to prevent the dial from fogging.
