Saint-Imier, Switzerland; later La Chaux-de-Fonds and Grenchen
Founded by Léon Breitling in 1884
Léon Breitling founded a workshop specializing in chronographs and precision counters in 1884. Successive generations refined independent chronograph pushers, cockpit instruments, and wrist chronographs; the Navitimer’s circular slide rule and the Superocean dive line made professional aviation and sport central to the brand.
