Control stem device for a watch

A control stem device for a watch, including:

• a first stem rotating about a longitudinal axis and provided with means for securing the first stem to a manual control crown on an exterior of the watch;
• and
• a second stem, substantially parallel and shifted in relation to the first stem and secured in rotation to a sliding pinion, the sliding pinion being mobile along a longitudinal axis of the second stem for selectively driving in rotation a mechanism for a first function and a mechanism for a second function;
• wherein the first stem and second stem are connected in rotation by a transmission device, wherein the second stem has a fixed axial position, while the first stem is mounted to be axially mobile at least between a first operating position associated with the first function and a second operating position associated with the second function, so as to activate, by sliding between the first and second operating positions, a pull-out mechanism comprising a lever engaged in a peripheral groove of the sliding pinion so as to cooperate with the sliding pinion and transmit axial movements of the first stem to the sliding pinion in such a way as to make the sliding pinion pass from a first axial position to a second axial position, the sliding pinion being meshed with the mechanism for the first function in one of the first axial position and the second axial position and with the mechanism for the second function in the other of the first axial position and the second axial position.
