This material, recognised to be one of the hardest substances, has been used at Tissot for decades. It is perfectly suited to the external parts of a watch that is exposed to daily scratching and impacts. Ceramic ingredients include aluminium oxide and zirconium, which means that it will never oxidise no matter how much time passes. That means the watch will never lose its shine. It is known for its hypoallergenic properties and is well suited to any wrist.

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.

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.

Ensuring visibility under all conditions is an important goal for Tissot. This is why some timepieces feature a material we call SuperLuminova®. This material is placed on visible parts such as dials and hands, where it functions as a miniature accumulator of reflected light when the watch finds itself in the dark.

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.
