Abstract
A movement construction for a small size analog quartz timepiece having a battery, a quartz crystal oscillator, an integrated circuit chip, an electro-mechanical transducer including a driving coil, stators and a rotor, and a wheel train driven by the electro-mechanical transducer to actuate a time-indicating mechanism. In one preferred embodiment, the driving coil, stators and battery are arranged in a predetermined order along the longitudinal axis of the movement construction and the integrated circuit chip is disposed to be in vertical alignment with the stators. In another preferred embodiment, the driving coil, stators and battery are arranged in spaces different from each other in a horizontal plane.
