From brave first takeoffs to the birth of commercial air travel, Breitling's history is inseparable from that of flight. IN the 1930's, Breitling Huit Aviation department made its name inventing precision cockpit clocks. Two decades later, it introduced yet another novel flght instrument, this time in wearable form: the Ref.765 AVI. That pioneering pilot's watch provided the technical backdrop for todays Classic AVI, a collection inspired by the rugged spirit of famed early aircraft. The Classic AVI P-51 Mustang honors one of those legends. When the aircraft was built in a mere 120 days, even its developer North American Aviation, didn't anticipate what a powerhouse it had on its hands. The P-51's low-drag wings and engine-cooling system-considered experimenal when the single-seat fighter first took off in 1940-gave it unprecedented speed and range. The addition of a Merlin engine expanded the plane's performance to high altitudes. makin if the best all-purpose fighter of its time. The kurled bezel on the 42mm case provides optimal grip, even in a pilot's gloved hands. The engine of the Classic AVI is the COSC-certified Breitling Caliber 23 movement, which rovides approximately 48-hours of power reserve.
