The case of the Sinn 756 uses "Tegiment" technology. The stainless steel case has been especially hardened by a thin outer layer of special anti-corrosive stainless steel which is also used in surgical implants. This protective shell is hardened to 1,200 Vickers (5 times harder than the regular stainless steel used in other watches).

What also makes this watch special is its extreme protection from magnetic fields. The case design and inner lining consist of a special iron core making this watch resistant to the effects of magnetism.

Another very interesting feature is Sinn's dehumidifying technology used in this watch: a copper sulphate capsule soaks up any diffused atmospheric humidity in the watch, resulting in a lengthened functional security within the movement.

Functionally reliable at temperatures from -45°C to +80°C thanks to Sinn Special Oil 66-228.

The dial's design guarantees excellent legibility with the highest possible amount of contrast between the strikingly shaped luminous hands, markers, and large numerals and the non-reflective black dial. Date display is subtly positioned at 4:30.
