The Breitling 765 was produced for about two years between 1964 and 1966 as part of the Premier line. This was the last watch to be made within the Premier line. In Breitling Lexicon, Premiers were the top of the line and predated the famous navigational instruments, such as the Chronomat and Navitimer, by debuting in the late 1930s. However by the mid 1960's Breitling was producing very technical watches such as the Navitimer Cosmonaute, the 806 and the Top time, the cost of producing the silver Ref. 765, with the same Venus 178 movement was too high and the brand discontinued the line.
This example has beautiful aging characteristics and would be a great addition to any Breitling collection.
