Your one-minute primer to the new Longines Lindberg Hour Angle.

Arguably the first true pilot’s watch, the original Lindbergh Hour Angle was designed in close collaboration with its namesake, who flew the first non-stop solo transatlantic flight in 1927. To celebrate the 90th anniversary of this feat, Longines released a limited edition (90 pieces) of the watch updated with several modern touches. Still maintaining its ability to accurately determine the longitude on long-distance flights, the automatic watch dons a resolutely urban, monochromatic look, along with a 47.5mm titanium case paired with a rotating bezel in black PVD steel.
