ABSTRACT:
An electronic timepiece movement includes a control stem slidably guided in a radial passage of a base plate. Pulling on this control stem brings a return spring acting on the stem into contact with a stud which is carried by the substrate of an electronic circuit module of the movement. This connects a conductive lead to ground, which controls an operation function of the timepiece. The pull-out control stem and associated return spring can be replaced by a push-in member and by a return coil spring located in said passage. The stud is then positioned in a hole of the substrate of the electronic circuit, which hole is situated opposite to the longitudinal axis of the passage. Pressure exerted on this push-in member places a portion thereof into electrical contact with the stud and this connects the lead to ground, as before. Thus, the movement can according to choice be completed for operation either by a push-in control movement or by a pull-out control stem movement.
