The sapphire glass – it’s perfect!
Sapphire is the 2nd hardest material after diamond. It is scratch resistant and therefore used in most outstanding timeless watches. Sapphire is the top choice.
The technology inside the glass
The whole payment technology is sealed inside the sapphire glass. The chip is protected by a notch and the antenna is hidden by a silver coating around the rim and the chamfer.
The design for every watch
Looks great on any analog watch dial. Moreover, the «hovering» notch clearly shows up that the watch owns that exclusive payment feature. A patented solution to circumvent the effects of the Faraday cage.
STISS stands for sustainable, convenient and contactless technology inside sapphire watch glass.
