NIVACHRON™
Themagnetic fields generated by our electronic objects (cell phones, computers, radios, magnets, etc.) are increasingly present in the environment.) are increasingly present in our daily lives, so Tissot, concerned about the precision of its watches, has developed a new, latest-generation titanium-based alloy. A balance spring in Nivachron™ is said to be far more resistant and insensitive to magnetic fields than standard balance springs.
POWERMATIC80
Anautomatic watch runs on the energy of its wearer. Wrist movements are what power the mechanism. The Powermatic 80 offers 80 hours of power reserve, enough to continue telling the time accurately even after 3 days without wearing the watch. An innovative, high-performance movement compared to the competition, which generally offers a power reserve of 1.5 days.Theproperties that a sapphire crystal brings to a watch are: extreme resistance to shocks and good legibility of the dial and hands thanks to its transparency. Sapphire crystal is the most robust material after diamond, and is used in the high-end watchmaking industry for its anti-scratch properties. The sapphire crystal can take on several shapes, giving the watch a variety of designs: flat, domed, hollowed or ground.All Tissot watch cases undergo numerous tests, including water-resistance. Tissot Thistests the watch's ability to withstand shocks and pressure, as well as the penetration of liquids, gases and dust, by reproducing the real-life conditions in which the watch might find itself.
