The Tag Heuer company has its roots in 1860 when Edouard Heuer founded a watchmaking company 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.Heuer introduced its first wrist chronograph in 1914. The crown was at the twelve o'clock position, as these first wrist chronographs were adapted from pocket chronographs. In 1916, Heuer introduced the "Micrograph", the first stopwatch accurate to 1/100th of a second. This model was soon followed by the "Semikrograph", a stopwatch that offered 1/50th of a second timing, as well as a split-second function (which allows the user to determine the interval between two contestants or events).
