In 1915, Breitling launched a wristwatch featuring a chronograph complication. Gaston Breitling, Léon’s son, had the inspired idea to introduce a push piece at 2 o’clock to start, stop and reset the chronograph functions.
In 1923, the start and stop functions were separated from the reset. The crown incorporated the reset function allowing the wearer to time successive events by repeatedly pressing the start/stop button without having to reset the registers.
The evolution of the chronograph continued. Willy Breitling, Léon’s grandson, had the idea to add a second push piece at 4 o’clock for resetting the stopwatch function. This design was subsequently copied by many watch brands and remains the norm for modern-day chronographs.
Jack Heuer approached Breitling in 1967 with the aim of sharing the development costs necessary to produce a new self-winding chronograph. Codenamed “Project 99”, the movement became the legendary Calibre 11, reputedly the first self-winding chronograph when released in 1969, albeit this may be contested by some brands. The Calibre 11 was housed in the legendary Heuer Monaco and Breitling Chrono-Matic collections.
Interestingly, all modern-day Breitling models, both mechanical and quartz, are certified chronometers, independently tested by COSC.
