From brave first takeoffs to the birth of commercial air travel, Breitlings history is inseparable from that of flight. In the 1930s, Breitlings Huit Aviation department made its name inventing precision cockpit clocks. Two decades later, it introduced yet another novel flight instrument, this time in wearable form: the Ref. 765 AVI. That pioneering pilots watch provided the technical backdrop for today is 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, did not anticipate what a powerhouse it had on its hands. The P 51 is low drag wings and engine cooling system considered experimental 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 is performance to high altitudes, making it the best all purpose fighter of its time. As a true pilots watch designed to withstand the rigors of a vintage cockpit, the Classic AVI P 51 Mustang features large, highly legible Arabic numerals on the dial and bezel. The knurled bezel on the 42mm case provides optimal grip, even in a pilots gloved hands. Top stitched calfskin straps give a nod to the seams found on classic flight gear, while the stainless steel bracelet provides an elegant alternative. Pilots and other travelers will appreciate its legibility, wearability, and understated style. The engine of the Classic AVI is the COSC certified Breitling Caliber 23 movement, which provides approximately 48 hours of power reserve.
