Abstract: The present invention relates to a control device (10) for a horological movement including, on the one hand, a first part (100) comprising a sliding guide tube (101) intended to be fixed relative to said horological movement and an activation module (120), and on the other hand, a second movable part (200) slidably guided by the guide tube (101) in a direction called “axial direction”, relative to said first part (100), between an active position wherein it is able to be integral, by means of an adjustment rod (201), with a component of the horological movement, and an inactive position wherein said adjustment rod (201) is intended to release the component of the horological movement, said second part (200) comprising a slider (202) fixed to the adjustment rod (201) and cooperating with the activation module (120) so that they exert mechanical stresses on each other when the second part (200) moves between the active and inactive positions, and so that these mechanical stresses are released when the second p
