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. A watch built from heritage, made for today.
