Gold

Gold is one of the most precious metals and prized in the world, it is recognized for its brilliance and its many technical qualities: stainless, insoluble, unalterable. Tissot uses 18K gold, a prestigious alloy of 75 % pure gold associated with a mixture of silver and copper useful for the production of gold. Thanks to Tissot's expertise and know-how, the pieces have an unmatched longevity, generation after generation.
™ Nivachron

The magnetic fields generated by our electronic objects (mobile phone, computer, radio, magnet, etc.) being increasingly present in our daily newspaper, Tissot, concerned with the accuracy of its watches, has developed a new generation of titanium base alloy. A balancer spiral in Nivachron™ is considered to be much more resistant and insensitive to magnetic fields than standard spirals.
Diamonds

Tissot is committed to guaranteeing the origin of the diamonds, as well as their quality-including colour, purity and size-present in its watches. They are all in compliance with the certification requirements of the Kimberley Process, an international certification system for rough diamonds.
Glace Saphir

The properties that a sapphire ice bring to a watch are: extreme resistance to shocks and good legibility of the dial as well as needles due to its transparency. This material being the most robust after the diamond, it is used in the high watch industry especially for its anti-stripe properties. The sapphire ice can take many forms and thus give the watch different design: flat, domed, crucified or furnished.
Etanchity

All the boxes of the Tissot watches are subjected to numerous controls, including the one of sealing. Tissot tests the capacity of the watch to withstand shocks, to pressure but also to the penetration of liquids, gases, dust by reproducing the real conditions in which the watch could be found.
