Chronomat B31 Automatic 40mm Men's Watch, Green Dial

Breitling’s ultimate all-purpose sports watch is ready for anything. The Chronomat holds a pivotal place in the brand’s modern history. Introduced for Breitling’s centennial 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 Tricolor. When the team asked for an analog timepiece that could withstand the intensity of a jet cockpit and still look stylish enough to be worn to formal events—Breitling developed the “Chronograph Frecce Tricolor.” It was the blueprint for the Chronomat to follow one year later. The Chronomat B31 40 is powered by Breitling’s COSC-certified manufacture caliber B31, unveiled in 2025. With a weekend-surviving 78-hour power reserve and slim dimensions, it’s a time and date timepiece for every occasion.
