This vintage Breguet Type XX Aéronavale ref. 3800 is one of the most iconic pilot’s chronographs ever produced, inspired by the military watches supplied by Breguet to the French Naval Air Force. Its 39 mm stainless steel case is paired with the original stainless steel bracelet, offering the perfect balance of sporty elegance and everyday wearability. The black tritium dial has developed a beautiful, even patina, enhancing the watch’s vintage appeal, while the rotating bezel and luminous Arabic numerals preserve its authentic aviation character. Powered by the automatic Breguet Caliber 582 (based on the Lemania 1350), it features a flyback chronograph function, renowned for its reliability and precision. Complete with its original box and papers, this is a highly collectible example of one of Breguet’s most celebrated modern classics.
