Tissot T-Classic T1434101109100 | Green Dial | 40mm Stainless Steel Quartz Watch

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. Tissot offers watches with an interchangeable strap system. The easy unlock system enables to remove the strap easily and quickly without the need of a tool. Interchangeable straps are the ultimate accessorisation. It offers greater choices to personalise your watch and to suit any occasion in two simple clicks.
