Abstract
The control device (1) for a timepiece has a body (4) intended to rotate about a rotation axis (X) in a case middle (2) of a timepiece to drive a mechanism of the timepiece, and a crown head (5) movable in translation relative to the body, parallel to the rotation axis, between a first position and a second position. The body has a first coupling (46) and the crown head has a second coupling (53), arranged so that in the first position, the body and the crown head are uncoupled, and in the second position, the body and the crown head are coupled. The control device has a first formation (47A) and a second formation (47B), and a locking element able to cooperate with the first formation to stabilize the first position, and with the second formation to stabilize the second position.

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.
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 body comprising a first indexing means and the crown head comprising a second indexing means, the first and second indexing means being arranged so as to stabilize the crown head in the first position and in the second position,
- the crown head comprising a tubular part and the body comprising an annular opening able to receive within the tubular part, the second coupling means being arranged on a first wall of the tubular part, and the second indexing means being arranged on a second wall of the tubular part, the second wall being opposite to the first wall.
