The house was founded by Edouard Heuer in Swiss St. Imier in 1860. In 1864, Heuer took out a patent on an innovative winding crown and inspired by a business travel to England, he turned to precision timepieces. In 1916, his sons patented a timepiece that allowed to record intervals in accuracy of a certisecond, and they qualified with this and many other timepieces as official timekeeper of the Olympic Games and in motorsports. Today Tag Heuer is one of the best-known luxury watchmakers in the world with models as Aquaracer, Carrera, Kirium, Link and Monaco.
