  • the selector lever 21 comprises, at a second free end, a hook 22 and a nose 23 between which is formed a recess in which the column wheel 40 is arranged.
  • the column wheel 40 is interposed between the hook 22 and the nozzle 23 in the preferred embodiment of the invention.
  • the selector member 20 is subjected to the action of a spring tending to maintain it in a rest position in which the hook 22 rests against the column wheel 40.
  • the hook 22 and the nose 23 are adapted to cooperate alternately with a ratchet 41 of the column wheel 40 each time the selector lever 21 is requested by the user.
  • the nozzle 23 comes into contact with a tooth of the ratchet 41 and subjects the column wheel 40 to a moment of force, causing it to rotate through a certain angle.
  • the spring causes said selector lever 21 to move into its rest position and the hook 22 to engage between two teeth of the ratchet 41.
  • the column wheel is then held in a position stable by the cooperation of the hook 22 and the ratchet 41.
  • the column wheel 40 comprises a plurality of cams 42 coaxial and superimposed on each other.
  • the cams 42 are integral with each other in rotation, as well as with the ratchet 41.
  • each of the cams 42 receives in support a transmission rocker 50 which is specific to it, so that, during the rotation of the column wheel 40, the transmission rockers 50 are driven in rotation alternative by said cams 42, between two extreme positions called in the rest of the text “rest position” and “active position”.
  • the cams 42 are configured so that, during the rotation of the column wheel 40, they cause the transmission rockers 50 to move alternately between their active position and their rest position.
  • the cams 42 are arranged so that only one transmission rocker 50 at a time is moved into the active position, said transmission rockers 50 being driven successively, one after the other, into their active position, when of the rotation of the column wheel 40.
  • the transmission rockers 50 being driven successively, one after the other, into their active position, when of the rotation of the column wheel 40.

  • the cams 42 preferably all have the same cam profile and have an angular offset relative to each other, as shown in the figures 1 And 2 .
  • the cams 42 each comprise, on the one hand, at least one circular sector 43 whose center coincides with the axis of rotation of said cam 42, and on the other hand, at least one tooth 44 extending radially beyond said circular sector 43.
  • the cams 42 each comprise three circular sectors 43 separated from each other by a tooth 44.
  • each transmission rocker 50 can be superimposed on one another and can be movable in rotation around the same axis of rotation in order to make the device more compact.
  • Each transmission rocker 50 extends between a first free end with which it is intended to cooperate with the column wheel 40 and a second free end with which it is able to cooperate with the control member 30.
  • each transmission rocker 50 includes a feeler 51 intended to be held against one of the cams 42 under the action of a spring.
  • one of the transmission rockers 50 occupies the active position, it is arranged on the trajectory of the control member 30 so that, when the latter is requested by a user from a rest position, it causes the transmission rocker 50 being in an active position, towards a control position of a function specific to it.
  • a transmission rocker 50 is driven into the control position, it is moved away from the column wheel 40 so that its feeler 51 is no longer in contact with the cam 42 associated with it.
  • the cams 42 are configured so that when the column wheel 40 occupies a predefined angular position, all of the transmission rockers 50 occupies its rest position.
  • the user can select a neutral state of the selection and control device 10, by requesting the selector member 20, in which no function of the watch movement can be activated by the control member 30.
  • each transmission rocker 50 includes a lug 52.
  • the lug 52 of each transmission rocker 50 is arranged at the level of the second free end, and extends from a lateral side of said transmission rocker 50.
