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, athletes, and astronauts. In 1962, it even became the first Swiss wristwatch in space. The anniversary edition features the famous slide rule in black on an attention-grabbing 18k red-gold dial. The strap is alligator leather with contrasting topstitching and an 18k gold folding buckle.
