The Tissot user's manual give information about the use, the settings and the maintenance of the different Tissot watches.



When electronic objects emerged in the 1930s, Tissot began harnessing its expertise to help its customers prevent interference between their watch movements and the magnetic fields generated by electronics. Nevertheless, magnetic fields continued to be a preoccupation for watchmakers. With the arrival of silicon as a new material to make components in the mechanism that controls a movement, Tissot can offer far greater resistance to the magnetic fields produced by everyday objects such as mobile phones, televisions, computers, hairdryers, radios or the magnetic closures on handbags. Thus, Tissot watches became even more accurate than before.

Powermatic 80

An automatic watch is powered by the energy of the person who wears it. Wrist movement enables the mechanism to run. The Powermatic 80 movement boasts 80 hours of power reserve, which is enough to continue telling time accurately even if the watch is not worn for three days. It is an innovative movement that outperforms the competition, whose movements generaly provide 1.5 days of power reserve.


A sapphire crystal gives a watch the following properties: extremely high resistance to impact and superior screen and hand readability thanks to its transparency. Because it is the strongest material after diamonds, it is used in fine timepieces for its anti-scratch prowess. Sapphire crystals can take many forms and give the watch a variety of looks: flat, domed, concave or ground.
Water resistance

All Tissot watch cases undergo several tests, including a water resistance check. Tissot tests the watch's ability to resist impacts and pressure, as well as the penetration of liquids, gas and dust by replicating the real-life conditions in which the watch may find itself.
