The straight lines and sharp edges in combination with the 45.5 mm case give the Tissot Supersport Chrono a strong personality.

The hand-sewn vintage leather strap harmonizes with the watch and gives the chronograph a sporty and trendy look. 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 Features of this watch include,30-minutes and 1/10 of a second counters, ADD and SPLIT functions, central 60-seconds chronograph hand, EOL (battery end-of-life indicator) & an interchangeable bracelet made from cow leather, with a standard buckle.
