The Tissot Gentleman is a multi-purpose watch, both ergonomic and elegant in any circumstance. It is equally suitable for wearing in a business environment, where conventional dress codes apply, as at the weekend, when it adapts easily to leisure activities. As part of the life of a modern, active man, the Tissot Gentleman becomes the perfect companion for every day, every occasion and every style. POWERMATIC 80An 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 general provide 1. 5 days of power reserve. SAPPHIREA 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 RESISTANCEAll 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.
