The Breitling Navitimer pushed the notion of tools associated with chronographs forward, offering every piece of data a pilot would need thanks to its ingenious slide rule (which was also found on the Breitling Chronomat since the early 1940s).
There is still some debate about the exact launch date of the Navitimer in the 1950s, but the prevailing examples date it to 1954, with this exact configuration.
Those very early Navitimers come with the all-black registers and the coveted caliber Valjoux 72 found only in the first years of production, but with a subtle difference: the 806 reference number cannot yet be found on the caseback. The Navitimer was originally a watch developed almost exclusively for the AOPA (Aircraft Owners & Pilots Association), hence the golden wing logo on the dial instead of Breitling branding.
This difference makes this Navitimer one of the rarest to find, especially in such outstanding condition
