Rare Breitling 765 AVI “Digital” stainless steel chronograph.The Digital was released in 1953, and so called for the window located at 3 o’clock. Normally a date window, this window counts down the chronograph to 15 minutes, for use by pilots. The watch is in overall excellent condition, the screw case appears untouched and measures 40 mm. the original dial is awesome too, with not a flaw in sight. The original radium lume is present on the dial with an aged patina. All functions work properly, feel free to ask for any other additional detail you may need.
