With an array of options, there is a model to suit everyone. 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 prowess. 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. Some unique features of this watch include, EOL (battery end-of-life indicator) & butterfly clasp with push-buttons. Battery type Renata 371 Width: 42.00 Length: 42.00 Thickness: 8.1 Weight: 139
