Hamilton Khaki X-Wing Automatic

The Khaki X-Wing Automatic watch is the world’s first watch with an integrated drift-angle calculator. The watch is designed first and foremost to help pilots calculate and record the crosswinds they encounter during their flight. This is achieved by using the external bezel and key information from either the control tower or from a map concerning the geographic and magnetic poles and wind speeds. Using the nomograph engraved on the reverse side of the watch, the pilot can calculate the speed. With this information, the air speed along with the outer and inner bezels on the watch, the pilot is informed of the direction he has to take to reach the desired destination directly. The watch has a diameter of 44 mm, is in stainless steel and is equipped with an ETA 7750 automatic movement. A black or silver-coloured dial is available, there are day/date apertures at 9 o’clock and the watch comes with a choice of a brown leather or black rubber strap or a stainless steel bracelet.
