ABSTRACT:
An analog electronic timepiece wherein oscillation of the oscillator circuit is stopped when the watch is placed into a reset mode. This lowers power consumption and provides for greater battery life during shipping and stocking periods. In one embodiment of the invention the oscillator is stopped immediately upon placing the watch into a reset mode. In another embodiment of the invention, cessation of oscillation does not occur until a predetermined delay after reset.
