The Breitling Chronomat has remained one of the company’s most successful and best-selling watches for over sixty years. This model was first developed in 1940, in line with the company’s patent application for the first circular slide rule feature in a chronograph wrist watch. Its immense commercial success prompted the development of a follow-on line, the Navitimer. In the sixties, a fully automatic Chronomat with a self-winding mechanism was introduced, making it the first and oldest automatic chronograph watch in the market. In later years, other features such as the moon phase indicator, countdown timer, and newer movements were added.
Until 2009, movements of all Breitling timepieces were outsourced to other Swiss watchmakers. The Breitling Chronomat B01 has the distinction of being the first model whose movement was created in-house by Breitling. At the heart of this distinctive luxury watch beats the Breitling Calibre B01 movement, engineered so precisely that time variation is just 0.3 seconds per day. It features continuous seconds at 9:00, a jumping 30-minute totalizer at 3:00, an instant date-change hammer at 4:30, and a central chronograph timer for seconds. Even with gloves on, you can easily pull up the watch’s hammers and dials to reset the time and date. As with other fine Breitling luxury watches, the Breitling Chronomat B01 is COSC-certified as a chronograph.
The Breitling Chronomat B01 has a 43-millimeter diameter case available in several variations, including all steel, steel bezel with gold quarter-hour markers, two-tone gold, and solid 18K red gold with diamond. Watch band options include leather straps in several shades, all stainless steel bracelet, two-toned bracelet, or solid gold bracelet. All Chronomat versions are water-resistant up to 100 meters, except for the solid gold version which is submersible up to 500 meters.
