Tissot SA (French pronunciation: ​[ti’so]) is a Swiss luxury watchmaker. Founded in Le Locle, Switzerland by Charles-Félicien Tissot and his son, Charles-Émile Tissot, in 1853. Since 1983, it has been a subsidiary of the Swiss Swatch Group. Not associated with another Swiss watchmaking firm, Mathey-Tissot.

A subsidiary of the Swiss Swatch Group since 1983, the largest watch producer and distributor in the world. After joining Swatch, it was still based in Le Locle, Switzerland, and marketed in 160 countries around the world.

Tissot luxury watches are currently classified by the Swatch Group as “mid-range market” products.

These luxury watches are the official timekeeper for the world championships in cycling, motorcycling, fencing and ice hockey, and so on. They were also a key sponsor for the Formula One team’s Lotus, Renault, and Sauber. For early events, handheld stopwatches were sufficient to provide official timings.

Today, the Swiss luxury watch brand works with various sporting bodies to develop systems to produce ever more accurate timings for specific events. In competitive cycling, for instance, sensors are placed on the bikes and track which are then linked by computers to provide track timings and performance data.
