I'm selling my Sinn 756 DIAPAL Tegimented UTC on Strap.
What makes this watch so special?
• Chronograph.
• Dual Time Zone - UTC
• Tegmented Coating - 5 times harder than standard steel
• a five year warranty
• a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the watch
• use of nanotechnology - an Automatic winding chronograph with oil free escapement
Its been out a half dozen times and has been sitting on a watch winder. It's in Like New condition, say 98%. All boxes, papers, and warranty card included. Original strap worn 2-3 times plus a SINN rubber strap which retails for $90.

some information about this unusual watch from the Watchbuys web site:

Beginning in 1995, Sinn began work to create an oil free escapement. With any mechanical watch movement, the aging of oil, especially in the escapement can create long term problems for that movement. Additionally, as movement oil ages, required service intervals become more frequent.
Sinn's early analysis to this problem provided a quick solution (at least in theory) - if you don’t use oil, it can’t age. The process began by exchanging the ruby escapements for diamonds (the word “DIAPAL” derives from the German name for diamond escapements, “Diamantpaletten”) in order to achieve the desired effect. The designation stuck, even though today Sinn works with solutions taken from advanced nanotechnology rather than diamonds.
The result is a movement that proves so reliable that Sinn offers an unprecedented five year warranty on their DIAPAL watches.
The case features a copper sulphate capsule which reacts with moisture to diffuse and absorb humidity in the 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 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.
Satin-brushed stainless steel case with solid back. Dial is anthracite with black sub-dials, Arabic numerals and offset date display at 4. We have to say this is one of the most striking dials we have ever seen on a watch. 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. The UTC feature or second time zone is indicated by an additional hour hand (pointing to 7 in our photograph). Watch is water resistant to 20 ATM.
