1. A control device for a timepiece, comprising:
a body intended to be mounted so as to be able to rotate about an axis of rotation in a case middle of the timepiece in order to drive a mechanism of the timepiece, and
a crown head movable in translation with respect to the body, parallel to the axis of rotation, between a first position and a second position,
the body comprising a first coupling means and the crown head comprising a second coupling means, the first and second coupling means being arranged so that when the crown head is in the first position, the body and the crown head are uncoupled, and when the crown head is in the second position, the body and the crown head are coupled,
the control device further comprising a locking element, a first formation and a second formation, the locking element being able to cooperate with the first formation to stabilize the crown head in the first position, and with the second formation to stabilize the crown head in the second position,
the locking element being integral with or fixed to the crown head and the first and second formations being integral with or fixed to the body, or the locking element being integral with or fixed to the body and the first and second formations being integral with or fixed to the crown head.
