BREITLING watches - Caliber B01

Breitling is marking an important date in its history by unveiling Caliber B01, its first chronograph “motor” designed and built entirely in-house. It is a logical evolution for a brand that has played a major role in developing the wrist chronograph and is counted among the leading makers of this complication. It is a perfectly consistent choice for one of the last independent Swiss watchmakers, which is thereby ensuring its freedom to maneuver and loyalty to its own criteria for excellence.

Through 125 years and five generations, Breitling has tied its name closely to the development of aviation, sports, technology, sciences and industry – all of these being areas that require reliable and accurate measuring instruments. With the B01, the company is more than ever confirming its calling to accomplish challenging feats, and beginning a new chapter in a history already replete with great moments in the air, on land and beneath the seas.

To guarantee its long-term independence and ensure that it has complete control over quality, Breitling is launching its own mechanical chronograph movement. The accurate, reliable, sturdy and efficient B01 is directly in line with the philosophy
of excellence that the brand has been pursuing for 125 years. This new caliber has a
column wheel, a vertical-trigger mechanism and a power reserve exceeding 70 hours, which ensures that the movement has a more regular rate. It was designed to maximize functionality and safety when in use. Breitling also gave it some assertively innovative features intended to increase its ease of manufacture and use, including
a patented mechanism for auto-centering the reset hammers and an exclusive index
regulator system that allows the watch’s timing to be quickly customized to the wearer. The B01’s intelligent architecture also offers significant advantages in terms of maintenance.
