Abstract

PURPOSE:To produce a proper output torque suitable to a state of the watch by controlling a feed time for a driving power circuit, which is for driving an electromagnetic converter, according to a change of the state of both the mechanical load and the line voltage. CONSTITUTION:When one driving signal from a driving-wave shaping circuit 3c of the watch circuit 3 is fed to inverters 4a, 4b of the converter driving circuit 4 and the delay circuit of a timer circuit 6b every second, the inverters 4a, 4b conduct, and the charge of a capacitor 5b flows to the winding F of a step motor SM. On the other hand, a signal is emitted from the delay circuit after a delay time, the switch circuit 6a is closed according to the signal that shows a state of the load provided from he terminals A, B, C of a driving-wave detecting circuit 7, and the capacitor 5b is charged up to voltage suitable to the degree of the load.
