1988 Longines Lindbergh Hour Angle ref. 989.5215

This is the model that is a smaller size, 38mm, of the original “Hour Angle” that was designed by Colonel Charles A Lindbergh.

It features a rotating inner dial that is used to calculate the longitude location while flying. Of course today, we have GPS, Satellites, etc that will give pilots their exact location. Back in Col. Lindbergh’s day, location was determined by celestial navigation using a sextant and compass, much as mariners navigated.

Longines was founded in 1832, its winged hourglass logo is the oldest registered trademark for a watchmaker.
Longines provided timers used at the first modern Olympics in 1896.
