The invention pertains to a double-acting control element for a wrist-top computer, comprising a crown, which can be moved in axially and radially, a reaction bar, connected to the and parallel to a crown's rotational axis. The reaction bar is arranged to transmit the movements of the crown from outside to the inside of a case. Switches are permanently fitted to the inside of the case. An axial switch is arranged to switch on from the axial movement of the crown. A radial switch is arranged to switch on from the radial movement of the crown. A slide, at least partly inside the case, is arranged to transmit the axial movement of the reaction bar to the axial switch and a gearwheel. The gearwheel is arranged to link the reaction bar to the slide to transmit the radial movement to the radial switch.
