Breitling, established in 1884 by Léon Breitling in Switzerland, has a storied history of crafting precision chronographs for scientific, sports, and industrial purposes. Over the years, the brand introduced key innovations such as the addition of push-pieces for chronograph control and the separation of start/stop and reset functions, which became industry standards. Willy Breitling's contribution of a second reset push piece further defined modern chronograph design. In collaboration with Jack Heuer, Breitling played a pivotal role in the development of the legendary Calibre 11, a pioneering self-winding chronograph movement. Today, Breitling models, both mechanical and quartz, proudly hold the distinction of being COSC-certified chronometers, reflecting their commitment to precision timekeeping.Breitling, established in 1884 by Léon Breitling in Switzerland, has a storied history of crafting precision chronographs for scientific, sports, and industrial purposes.
