In-Depth The Science, History, And Romance Behind The Longines Lindbergh Hour Angle Watch

“As all experienced navigators know, it is extremely easy to get lost.” —Philip Van Horn Weems, Air Navigation, 1931

"Where are we? Directly above the center of the Earth." —Old Joke

Possibly one of the most unusual and unlikely timepieces in Longines’ very extensive heritage collection is this one: the Lindbergh Hour Angle, which is an almost exact replica of an historical timepiece made by Longines and distributed in the USA by Longines-Wittnauer, in 1930-31. Lindbergh designed the watch – whose features we’ll get into in depth in a minute – in order to ease a pretty challenging task. That task is figuring out where you are, which nowadays we take for granted; finding out your location, thanks to a global Internet and satellite network, has become a trivial thing. You probably have some general notion that navigation wasn’t exactly a walk in the park before GPS, and if you are into watches you’ve probably heard of a guy named John Harrison, who invented the first reliable marine chronometer all the way back in 1761. The problem with the Lindbergh Hour Angle Watch is that almost none of us seem to understand exactly how it was supposed to work. But thereby hangs a tale. To understand why the Lindbergh Hour Angle watch looks the way it does – and why you might just want to wear such an outlandish, archaic looking, huge wristwatch – you have to dig just a little bit deeper, which is what we’re going to do now. Besides, a watch that made the cut for the Smithsonian deserves a little respect.

Here is an article (in French, sorry) from a 1933 copy of "lAeronautique" about the Hour Angle and it's usage.


Here is a cover from early June 1927 edition of "l'Aerophile" magazine signed by Lindbergh after his flight across the Atlantic.


And the French Aero Club "certificate of landing" again signed by Lindy.

Really nice historical documents related to this watch. This hour angle is well reported but these bring additional detail to the story. Really nice.
