Tissot T-Classic CollectionSwiss Quartz Watch With A Grey Stainless Steel Bracelet Strap, 38mm Case & Black Rhodium Coloured Dial. The new Tissot Everytime watches are simple yet classic Swiss made watches that can be dressed up or down and are timeless. With different dial designs and case sizes available, there is a model for all. SAPPHIRE GLASS 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 rowess. 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.
