A device for adjusting horological functions of a timepiece, including a mechanism for selection and actuation, including: a drive driving a driving pinion in the clockwise and anti-clockwise directions, a driven pinion driven when the driving pinion turns clockwise and anti-clockwise, the driven pinion moving into a first position by the driving pinion turning clockwise, in which the driven pinion actuates an actuator of a first horological function, and moving into a second position by the driving pinion turning anti-clockwise, in which second position, the driven pinion actuates an actuator of a second horological function, the driven pinion not actuating the actuator of the first horological function when it is in its second position, and vice versa. The mechanism for selection and actuation includes at least two driven pinions, and the adjusting device includes a control mechanism selectively bringing the driving pinion into engagement with each of the driven pinions.

The invention relates to a balance wheel-hairspring oscillator (10) comprising: a balance wheel shaft (18) intended to be pivotably mounted on a frame of a timepiece; a balance wheel (12) secured to the balance wheel shaft (18); a hairspring (14) comprising an inner end (14a) secured to the balance wheel shaft and an outer end (14b) intended to be connected to a connecting member (16) to said frame, and a transmission member (20, 22) arranged to interact with an escapement. The balance wheel (12) and the hairspring (16) are arranged on either side of the transmission member.

The invention relates to a method implemented by a computer terminal for assisting the setting of a mechanism of a mechanical timepiece (10). The method comprises the following steps: i) capturing an image or a sequence of images of the mechanical timepiece (10) by means of a computer equipment (20) comprising an image acquisition device (22) and a display area (24); determining the setting to be made according to said image or sequence of images, and displaying on the display area (24) of the computer device (20) a sequence of instructions for said setting of the mechanism.

A sympathique watch (10) including a horological movement including a going train (20), a display train (30) connected to at least one display of a time value, a sympathique hand-setting mechanism and a crown (13) operated hand-setting mechanism. The sympathique hand-setting mechanism includes a coupling device (40) interposed between the going (20) and display (30) trains, the coupling device (40) being configured to adopt an uncoupled state in which it disengages the going train (20) from the display train (30) so as to allow the hands to be set on the display by means of the sympathique hand-setting mechanism, and a coupled state in which it establishes a kinematic link between the gear trains, the link allowing for sliding enabling the hands to be set on the display by means of the crown (13) operated hand-setting mechanism.
