Abstract

The analog electronic timepiece has a plurality of functions, each driven independently by a dedicated step motor. A stem, pullable to three positions and a plurality of pushbuttons control operation. Each indicator hand may be set to zero independently by operation of an external button when the electronic circuits indicate that the respective hand should be at the zero position. A single frequency signal source and divider network provide frequency signals to all functions. Phase shifting circuits assure that driving signals to the independent motors are never concurrent.
