Tissot introduced its first T-Touch in 1999. The first editions were originally inspired by aviator watches with a design based on the cockpit dashboard with it's meters and gages and compass. A key feature of the watch has always been the combination of analogue and digital functionalities, and of course activation by a simple touch to the (sapphire) crystal. Watches containing this technology have various functions like compass, barometer, altimeter and thermometer. The latest models in the T-Touch series, have over 25 functions!
