ABSTRACT:
An electronic timepiece comprising a means for generating a base signal, an electromechanical transducer to convert the base signal into mechanical motion of a rotatable shaft, only a back side chain of wheels and a driving means whereby the back side chain of wheels is directly driven by the rotatable shaft. Furthermore, the driving means is coupled to the rotatable shaft such that idling rotation of the driving means occurs without rotation of the rotatable shaft when the timepiece is being set externally.
