Breitling (estb. 1884), founded by Léon Breitling in 1884, is Swiss company specializing in making chronographs and timers intended for sports, science, and industry. In 1915, Breitling invented the first independent chronograph pushpiece that allowed for the emergence of the wrist chronograph. Later in 1923, the firm perfected this system by separating the stop/start functions from that of resetting. In 1969, the firm presented the first self-winding chronograph movement. In 1984, Breitling revisited the mechanical chronograph and launched the Chronomat, which has become its leading model.
