Notes

This hour angle system is called the Weems Model because of its inventor: Professor and Instructor Philippe Vanhorn Weems, of the Naval Academy of Annapolis, who was an authority in the 1920-30's. He formed the famous Charles A. Lindbergh who established the record for the first non-stop transoceanic flight. The hour angle watch "Lindber gh Model" used for this flight is drawn from the Weems invention. Professor Ph. Weems wrote several important books and received a Gold Medal from the International Aeronautic Federation. The Longines Weems second-setting watch is made in two styles. The smaller model is useful not only for sea and air navigators and airline pilots, but particularly for radio broadcasters and others, such as civil engineers, requiring exact time.
