Breitling Navitimer B01 Chronograph 43

The Breitling Navitimer B01 Chronograph 43 is the quintessential pilot's watch — a flying instrument that has accompanied aviators since its introduction in 1952. The Navitimer was originally developed in partnership with the Aircraft Owners and Pilots Association (AOPA) as a wrist-worn flight computer.

Movement

The Breitling Manufacture Calibre B01 is an entirely in-house designed and produced chronograph movement, COSC certified, offering a 70-hour power reserve. The column-wheel control and vertical clutch system ensure chronograph precision that meets aviation standards.
