In the mid-1940s, Heuer expanded its line of chronographs to include two- and three-register models and a three-register chronograph that had a full calendar function (day/date/month). All these Flieger chronographs had two-registers, with a capacity of 30 minutes.' The earlier version featured a hinged-back case and one pusher (for start/stop/reset) the later version had a snap-back case and added a second pusher (for time-in and time-out). Over the period from 1935 through the early 1940s, Heuer manufactured chronographs for pilots in the Luftwaffe, known as 'Flieger' (pilot) chronographs. The companion 'Hervue' was a clock that could run for eight days without being wound. In 1933, Heuer introduced the 'Autavia', a dashboard timer used for automobiles and aviation (whence its name, from 'AUTos' and 'AVIAtion'). This model was soon followed by the 'Semikrograph', a stopwatch that offered 1/50 of a second timing, as well as a split-second function (which allows the user to determine the interval between two contestants or events). In 1916 Edward Heuer's son, Charles-Auguste, introduced the 'Mikrograph', the first stopwatch accurate to 1/100 of a second. The crown was at the 12 o'clock position, as these first wrist chronographs were adapted from pocket chronographs. Heuer introduced its first wrist chronograph in 1914.

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. 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). 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. In 1911, Heuer received a patent for the 'Time of Trip', the first dashboard chronograph. Įdouard Heuer patented his first chronograph in 1882 and in 1887 patented an 'oscillating pinion' still used by major watchmakers of mechanical chronographs. In 1860 Edouard Heuer founded Uhrenmanufaktur Heuer AG (English: Heuer Watchmaking Inc.) in St-Imier, Switzerland. TAG Heuer Carrera automatic chronograph with tachymeter 1860 through 1880s
