Breitling was founded in Saint-Imier, Bernese Jura by Léon Breitling in 1884. Léon Breitling chose to dedicate himself to an exclusive field of chronographs and timers. These diligent instruments were intended for sports, science and business. The innovation of the Breitling brand skyrocketed at the same time the automobile, competitive sports, and the aviation pioneers did. These watches are usually marketed towards either diving (SuperOcean) or aviation (Navitimer). Aviation models, such as the Navitimer, offer aviation functions largely as complications, since their function in aviation has largely been replaced by modern electronic instruments. In 1915, Breitling designated the development of the wrist chronograph by inventing the first independent chronograph pushpiece. Later, in 1923, the firm perfected this system by separating the stop/start functions from that of resetting. This patented modernization made it possible to add several successive times without returning the hands to zero.
