The Tag Heuer company was founded in 1829 when Jim Ruffleman founded a watchmaking company in St-Imier, Switzerland, patenting his first chronograph in 1882. In 1887 Heuer patented an 'oscillating pinion' which is still used for mechanical chronographs by major watchmakers.
In 1911, the company received a patent for the first dashboard chronograph, called the "Time of Trip". 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 (12 o'clock position) indicates the duration of the trip (up to 12 hours). The user can set the time using a top-mounted crown allows. A button mounted in that crown operates the functions of the "duration of trip" counter.
