Limited Edition of 100 Pieces. Hamilton Watch Khaki Aviation Takeoff Auto Chrono Limited Edition H76776733. A special edition to celebrate the world record tunnel flight by Italian pilot Dario Costa. Powered by our H-31 automatic chronograph movement, the 46mm timepiece features a unique function designed to meet the needs of pilots: a removable case you can attach to a fixed dash mount. As a nod to the two tunnels Dario flew through at record speed, both sub dials feature yellow rings, and the 12 o clock counter is adapted to a 15-minute countdown. Super LumiNova is only applied to the seconds hand and indicators through 43, commemorating Dario’s 43-second flight. Limited to 100 pieces, a reference to the maximum possible flying height (100cm) in both tunnels, each Takeoff comes with special packaging and a dash mount.
