Abstract
PURPOSE: To realize a 3-hand analog electronic watch which can perform the time correction for only hour and minute hands through the electronic hand setting and without any clutch mechanism nor slip mechanism, by using the planetry gears for the train wheels.
CONSTITUTION: Pinion 7a of rotor 7 turns speed resuction gear 6, and then pinion 6a of gear 6 intermeshes fifth wheel 5. Internal gear 5b of wheel 5 turns the second wheel 4 and minute wheel pinion 9a via platnetry gear 3 intermeshing fifth wheel pinion 5c which is fixed by corrector lever 12. Thus the hands are moved. At the time correction, lever 12 performs no correction, and instead correction lever 13 gives correction to the second hand. And pinion 3b of gear 3 transmits the turning power to minute wheel 9, and thus only hour and minute hands are turned to carry out the time correction.
