Breitling’s ultimate all-purpose sports watch is ready for anything. The Chronomat B31 40 holds a pivotal place in the brand’s modern history. Introduced for Breitling’s centenary in 1984, at a time when quartz movements dominated, it marked a bold return to mechanically driven watches.
It was born from a collaboration with the beloved Italian aerobatic squadron, the Frecce Tricolori. When the team asked for an analogue timepiece that could withstand the intensity of a jet cockpit while remaining stylish enough for formal occasions, Breitling developed the “Chronograph Frecce Tricolori”. It became the blueprint for the Chronomat, which followed one year later.
The Chronomat B31 40 is powered by Breitling’s COSC-certified manufacture calibre B31, unveiled in 2025. With a weekend-surviving 78-hour power reserve and slim dimensions, it is a time-and-date watch designed for every occasion. Available with a range of colourful dials, the Chronomat features the fully integrated signature Rouleaux bracelet, complete with on-the-fly adjustable links on both sides of the clasp.
The case is water-resistant to 200 m, making it ready for every environment.
