Introduced in 1954, the Breitling AVI Co-Pilot first generation had a digital minute counter instead of the "classic" 15 minute counter subdial. This unusual minute counter was soon replaced by the more common fifteen minute counter seen in other watches specifically the Type 20 from Breguet, Vixa and Auricoste which were based on a requirements established by the French Armée de l'Air.
The AVI co-pilot was often a procurement watch, used by military pilots whose governments did not issue a watch. Starting in the late 19860's the AVI line experienced a few different variations for specific purposes such as Yachting but also cosmetic changes and was fitted with a Black bezel and silver subdials for better contrast. It was famously worn by Raquel Welch in the Movie Fathom and the brand use that notoriety in a subsequent advertising campaign .
This example is an early version of the second generation the AVI 765 with a steel rotating bezel and all black dial. A great classic military Chronograph look for a fraction the price of a Breguet Type 20.
