For our 140th anniversary, we introduced the Caliber B19—Breitling’s first exclusive perpetual calendar chronograph movement. The milestone achievement now powers this special-edition Navitimer, a watch with its own legendary history.First created in 1952 for the Aircraft Owners and Pilots Association (AOPA), the Navitimer was designed for precision in the cockpit, combining a chronograph with Breitling’s patented circular slide rule. Pilots swore by its flight-computer functionality, but its appeal soon extended beyond aviation—to star athletes, musicians, and even astronauts. In 1962, it became the first Swiss wristwatch in space.This edition bridges past and future: a steel case, platinum bezel, ice-blue dial, and the remarkable B19 movement—an automatic chronograph with a perpetual calendar. Case size: 43 mm. A watch built from heritage, made for today.
