Since its founding by Léon Breitling in 1884, Breitling has been the benchmark for quality in chronograph manufacture. It launched the Chronomat in 1941 and conquered the hearts of not just military pilots, but also sports enthusiasts looking for utmost precision.
The first wristwatch with a circular slide rule function, the Breitling Chronomat made it super easy to do calculations on the go. One could use it to convert speeds or distances from one unit of measurement to another, and for other complex calculations too. This iconic watch laid the foundation for the launch of Breitling’s most popular pilot’s watch to date — the Navitimer.
Introduced in 1952, the Navitimer offered a circular slide rule on the rotating bezel to help pilots calculate flight time, distance, air speed, fuel consumption and more. The brand is also credited with having participated in the creation and marketing of the first modular automatic chronograph movement in 1969 — the Chronomatic.
