TAG Heuer is a Swiss luxury watchmaker known for its sports watches and chronographs. It is a division of luxury goods company LVMH Moët Hennessy • Louis Vuitton. The company motto is "Swiss Avant-Garde Since 1860". In addition to watches, TAG Heuer produces glasses and cell phones. The TAG Heuer company has its roots in 1860 when Edouard Heuer founded Uhrenmanufaktur Heuer AG in St-Imier, Switzerland, patenting his first chronograph in 1882. In 1887 Heuer patented an 'oscillating pinion' still used by major watchmakers for mechanical chronographs. In 1911, Heuer received a patent... for the "Time of Trip", the first dashboard chronograph. Designed for use in automobiles and aircraft, two large hands mounted from the center pinion indicate the time of day, as on a traditional clock. A small pair of hands, mounted at the top of the dial indicates the duration of the trip . A top-mounted crown allows the user to set the time; a button mounted in that crown operates the start / stop / reset functions of the "duration of trip" counter. Heuer introduced its first wrist chronograph in 1914.
