7 (1927) LONGINES LINDBERGH HOUR ANGLE WATCH
In 1927 Charles Lindbergh flew solo across the Atlantic in a record time of 33 hours and 30 minutes. This pilot lived and breathed aviation, and one of the offshoots of his lifelong pursuit was the Hour Angle Watch, which he designed as a navigational aid for pilots. The watch was manufactured by Longines to Lindbergh’s specifications. Highly visible in a 47.5mm case, the original Hour Angle Watch was conceived to be used together with a sextant, a nautical almanac, and a radio set for receiving the time signal. Thus a pilot could determine the Greenwich hour angle, meaning longitude. During the early days of aviation, the Hour Angle Watch was a pilot’s staple instrument.
