Tissot uses the greenest of energy sources to power its iconic T-Touch collection: Expert Solar and Connect Solar. Tiny solar sensors located on the watch dial capture light that is stored in an accumulator. The energy needed to run the quartz usually comes from a battery, but here the energy comes from natural or artificial light. This sustainable technology is enabling Tissot to create watches that run for several months without ever needing a recharge.

Tissot developed the first tactile watch 20 years ago. This high-tech feature improves watch ergonomics and makes it unique and intuitive to use. The technology offers an array of functionalities ‒ compass, altimeter, weather, alarm, chronograph ‒ without an abundance of buttons or complex sub-menus.

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.

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.
