Notes

Longines “Hour-Angle” watch
The “Hour-Angle” system was invented by Philip Van Horn Weems (1889-1979) of the Annapolis Naval Academy, an authority in the 1920’s and 1930’s. He trained the famous Charles A. Lindbergh (1902-1974), who set the record for the first non-stop transoceanic flight.
The watch was intended for rapid determination of longitude during flight. As a navigational instrument for airplane pilots, is used in conjunction with a sextant and the appropriate nautical tables, to permits the rapid computation of the Greenwich hour angle, that is, the aircraft’s longitude.
