Electronic timepiece

Image Number 7 for United States Patent #4212158.

An electronic timepiece having an intermittent driving means for rotating the second hand step by step, in which the second hand may be driven in two or more ways, one of by a large step as driving the second hand at the rate of one step per second and the other is by a small step such as driving the second hand at the rate of ten steps per second. There is provided a large step driving pulse producing circuit, a small step driving pulse producing circuit, a transducer for transducing the pulse into the rotating motion, a large step transmitting means, a small step transmitting means, a train for transmitting the rotating motion to the second hand, and means for changing the pulses applied to the transducer and for changing the transmitting means.
