The invention relates to a control device for a watch case comprising a case middle delimiting an inner volume in which a movement is located, with the device comprising a mobile-mounted rotary bezel on the case middle and a transmission component comprising: a mobile-mounted rotating stem in a hole traversing the case middle, with a first cam located within the inner volume of the securely mounted case middle rotating at the tip of the stem, and acting in unison with a control lever mounted on the movement when the transmission component turns and a second cam located on the outside of the volume, securely mounted and rotating with the other extremity of the stem, and comprising at least one support surface. The case middle comprises yet another contact surface designed to act in unison with the support surface when the case middle turns, so that it includes the transmission component in the rotation. The control device also contains a return spring acting on the case middle.
