The Wrights took to the air on 17 December 1903 from the beach of Kitty Hawk, North Carolina, making two flights each from level ground into a freezing headwind gusting to 27 miles (43 km) an hour. The first flight, by Orville, of 120 feet (36.5 m) in 12 seconds. The next two flights covered approximately 175 and 200 feet (60 m), by Wilbur and Orville respectively. Their altitude was about 10 ft above the ground.
The "instrument" used by the Wright brothers was a chronometer movement from Vacheron Constantin housed in a steel case with lugs enabling a long strap to be attached to the case and worn on the thigh.
Initially made in a series of five, one example is now exhibited in the Vacheron & Constantin museum in Geneva.
Cartier can say what they want but the Santos flight was in 1906, 3 years after the Wright brothers making VC the 1st airborne flight watch!!!
