Breitling Super Chronomat B01 44

The chronographs inside the Chronomat collection are fitted with the in-house B01 calibre. Released in 2009, the B01 was the first that was crafted entirely in-house by Breitling. What was special about the movement was the addition of a vertical coupling system, a speciality reserved for only the best watchmakers in the industry.
The B01 is an automatic movement that offers a power reserve of approximately 70 hours.
