Longines Lindbergh Hour Angle Watch 90th Anniversary

This year, Swiss watch brand Longines is celebrating the 90th anniversary of the first ever non-stop solo transatlantic flight, which was flown by Charles Lindbergh and timed by the Swiss watchmaker. For the occasion, the brand is presenting 90 timepieces in a numbered and limited edition of its hour angle watch, which was designed in partnership with the famed aviator following his historic flight. This exceptional titanium and steel timepiece is intended for those who are passionate about history, adventure and watchmaking.
On 20 May 1927, a young American pilot named Charles A. Lindbergh lands at Le Bourget airport in Paris after completing the first ever non-stop solo transatlantic flight that took off from Roosevelt Airport. As official timekeeper for the World Air Sports Federation, Longines contributed to the homologation of this prowess by timing Lindbergh’s flight and adding it to the list of aviation records.

Shortly thereafter, a close collaboration between the aviator and the brand produced the Longines Hour Angle watch, a veritable icon in the history of the Swiss watchmaker. Designed by Charles Lindbergh himself in partnership with Longines, this watch allows for accurate determination of the longitude during long-distance flights. As a result, pilots and navigators can find their geographic location quickly, efficiently and with great accuracy.
Longines Hour Angle watch, the Original
Today, Longines commemorates the 90th anniversary of Charles Lindbergh’s amazing feat and of its timekeeping, by releasing The Lindbergh Hour Angle Watch 90th Anniversary, a new edition of the legendary timepiece in a numbered series limited to 90 watches. Equally as impressive as the original timepiece, this model measures 47.5 mm, which makes it easier to read and manipulate in the dark and when subjected to the vibrations that were common to aircraft of the era. It will draw the attention of admirers when worn on the wrist of today’s modern adventurers. Equipped with a rotating bezel that allows for correction of the equation of time and a rotating central dial that allows for synchronization to the second, this timepiece indicates the hour angle in degrees and in minutes of arcin addition to indicating hours, minutes and seconds.
The understated brushed silver dial displays the time on a “railtrack” minute circle with painted Roman numerals, and features a 180° scale for calculating the longitude. The synchronization of the second hand with a radio time signal is accomplished using the galvanic black rotating central dial, while the black PVD steel rotating bezel allows for daily variations in the time equation to be taken into account. A L699 automatic calibre is housed in the titanium case of the 90th Anniversary Lindbergh Hour Angle watch, which is adorned with a large steel crown that is easy to wind or set, even with gloved fingers. The brown leather aviator-type strap equipped with an extension that allows the watch to be attached to an oversized pilot’s jacket puts the finishing touch on this exceptional timepiece.
