Breitling presents the Chronomat B31 Automatic 40 as its all-purpose sports watch. The Chronomat line was introduced for Breitling’s centennial in 1984 and grew out of a collaboration with the Italian aerobatic squadron Frecce Tricolori. This reference pairs a 40 mm stainless steel case, 10.99 mm thick, with a white dial, a date aperture and a unidirectional ratcheted bezel. Inside is the COSC-certified Breitling Manufacture Calibre B31, unveiled in 2025, with a power reserve of approximately 78 hours. The integrated polished and brushed steel Rouleaux bracelet has links that adjust on both sides of the clasp. The crown is screw-locked and the case is water resistant to 200 metres.
