LONGINES Hour Angle Lindbergh Chronograph Ref.674.52.32, cal. L674.4

— A mechanism drawn by a hero of the air —

"Designed by Col. Charles A. Lindbergh" is engraved on the movement. Longines, an old house by any measure, took inspiration from classical aviation instruments and built the watch Lindbergh himself conceived — a collector's item in the fullest sense.

The legendary navigation watch realised by Longines from the ideas of the man who flew the Atlantic alone. Its hour-angle system lets the wearer read a position from the sky, and the result is a rare kind of practical beauty.

— Lindbergh and Longines —

Charles Lindbergh made the first solo transatlantic flight in 1927. Out of that experience he designed a watch that would be genuinely useful for air navigation, and Longines was the maker that turned the idea into a mechanism.

— The hour-angle system —

Released in 1931, the watch lets the pilot read an "hour angle" from the position of the hands and the graduations on the rotating bezel, and from it determine the aircraft's longitude in flight. Just as sailors had relied on the marine chronometer to fix a ship's position, the hour angle became essential equipment for pilots at a time when aviation instruments were still primitive — and it raised Longines' reputation for precision and reliability another notch.

— A working instrument that never retired —

Which is why the Hour Angle — the "Lindbergh" — is still made today in models that keep the original function and design: a navigation watch whose popularity has never faded.
