Founded in 1884 in Saint-Imier, by the Swiss engineer Leon Breitling to manufacture exclusive watches and specialized in the construction of chronographs and counters. In fact, in 1915, Breitling invents the first independent chronograph button, released for the first time from the crown, and resumes the functions of start, stop and reset. This watch will be the precursor of the wrist chronograph. In the following years, he perfected this system by separating the chronograph functions of start and stop of the reset function. In this way, it was possible to add the times without having to reset the hands.
