The company was founded in Le Locle, Switzerland by Charles-Félicien Tissot and his son, Charles-Émile Tissot, in 1853. Tissot developed the first tactile watch 20 years ago. This high-tech feature improves watch ergonomics and makes it unique and intuitive to use. The technology offers an array of functionalities ‒ compass, altimeter, weather, alarm, chronograph ‒ without an abundance of buttons or complex sub-menus.Tiny solar sensors located on the watch dial capture light that is stored in an accumulator.Tissot markets COSC-certified watches, which means they are approved stopwatches. This certificate is issued by the COSC (Official Swiss Chronometer Testing Institute).
