Breitling Navitimer B19 Chronograph 43 Perpetual Calendar 140th Anniversary

The Navitimer was the first watch for pilots to combine a chronograph with the brand’s proprietary wrist-worn circular slide rule. Originally developed in 1952 for members of the Aircraft Owners and Pilots Association (AOPA), the Navitimer quickly found favor with a broader audience that included celebrities and astronauts—in 1962 it became the first Swiss wristwatch in space. The anniversary edition features the famous slide rule in black on an attention-grabbing 18 k red-gold dial. The strap is alligator leather with contrasting topstitching and an 18 k gold folding buckle.
