This is a very rare example of 1959-1960 Breitling AVI Ref. 765 called "all black" due to the colour of dial and registers. Stainless steel untouched screw back case, measures 42 mm ca. fits a "big beaded" s/s bezel very crisp. The original all black dial is in awesome condition with a beautiful aged lume on dial and hands. The watch is powered by the Venus 178 manual winding caliber. Overall in excellent condition, all functions work properly, a very rare and interesting chronograph to add in your collection. Feel free to ask for any further information.
