How the Longines Lindbergh Hour Angle Simplified Longitude Calculation
In 1927, Charles Lindbergh made history by becoming the first person to fly solo across the Atlantic, but his navigation relied heavily on dead reckoning. Recognizing the limitations of this method, Lindbergh sought the expertise of Philip Van Horn Weems, an innovator in navigation who had developed the Second Setting Watch in collaboration with Longines. Inspired by Weems' work, Lindbergh envisioned a watch that could assist in calculating longitude using celestial navigation, leading to the creation of the Longines Hour Angle watch. This timepiece featured a rotating bezel and provided a systematic approach to determining longitude, which is more complex than latitude. The Hour Angle watch operates by distinguishing between mean time and true solar time, allowing navigators to set the bezel accordingly. By using a sextant to determine local solar time and comparing it to Greenwich Mean Time, the user could calculate their longitude. Although Lindbergh did not use the Hour Angle watch during his famous flight, it became an essential tool for early aviators. This timepiece not only contributed to aviation navigation but also laid the groundwork for various watch innovations, remaining a significant piece of horological history with modern versions priced around £5,050.
