Notes

On April 12, 1878 August von Loehr of Vienna filed for a British patent for a self-winding watch with a special simple overwinding prevention system and a special setting mechanism. On July 13, 1878, he filed for a USA patent, which was granted on January 7, 1879 (No. 211280). Before Loehr?s invention, self-winding watches required an elaborate disengaging system when fully wound. Loehr overcame this problem in a very simple way by employing an elastic ratchet pawn.
