Abstract: A support for a mechanism for displaying jumping-type information for a timepiece movement is disclosed. The mechanism may include a display member driven in rotation via a driving star wheel. The support may be positioned between the display member and a frame element of the timepiece movement. The support may include a base that may include at least one first hole configured to receive a shaft for rotating the display member. The support may also include a first arm extending from the base and arranged to ensure the function of a jumper for the driving star wheel, and a second arm extending from the base and arranged to act on the driving star wheel to cause the driving star wheel to rotate in order to correct information displayed in response to a predefined action of a user that deforms the second arm.

Abstract: A display mechanism is disclosed for displaying the day and date in large date form, for a timepiece movement. The display mechanism may include first and second concentric disks, respectively for displaying the tens of the date and for displaying the units of the date. The first disk may have a diameter greater than that of the second disk. The first and second disks may be respectively attached to first and second star wheels each having a toothing. The display mechanism may also include a programmed wheel arranged to drive the first and second star wheels in rotation. The programmed wheel may include first and second outer toothings arranged to cooperate respectively, at least indirectly, with the first and second star wheels. The first toothing may have a diameter less than that of the second toothing.

Abstract: An instantaneous driving mechanism for a timepiece movement is disclosed. The driving mechanism may include a mobile comprising a first wheel driven by a driving member of the timepiece movement and configured to drive rotation of a first cam of the mobile. The driving mechanism may also include a lever mounted pivotally on at least one frame element of the timepiece movement, the lever being configured to cooperate with the mobile in order to be moved and to cooperate with a counter of the timepiece movement to increment the counter by instantaneous pulses. The first cam may be coaxial with the first wheel and have a periphery of varying radius. In addition, the first cam may be configured to cooperate with a nose carried by a first arm of the lever and to move the first arm progressively away from the center of the mobile.

Abstract: An actuating mechanism for a timepiece movement is disclosed. The actuating mechanism may include a first mobile driven by a driving mobile of the timepiece movement, and a second mobile mounted to rotate on a frame element of the timepiece movement and control a displacement of at least one driven mobile of the timepiece movement to actuate at least one additional mechanism. In addition, an elastic member may be provided to act on the second mobile and define a rest position thereof.

Abstract: A jumper for a timepiece movement is disclosed that includes a base and an elastically deformable arm extending from the base and provided with an abutment surface intended to cooperate with a notch of a mobile. The base may comprise a support element bearing the arm. The base may further comprise two link elements each linking an end of the support element to a fixed element of the base. The jumper may be associated with a control member arranged in such a way that an axial rotation of the control member provokes a displacement of the support element by deformation of a frame, of which the support element and the two link elements form sides.

Abstract: An inverter device for timepiece movements is disclosed which includes first and second toothed wheels intended to be driven in opposite rotation directions and coaxial with an output toothed member intended to be kinematically connected to a pivoting member of the timepiece movement. The wheels are connected to the output member by unidirectional transmission members adapted to transmit to the output member rotation in only the same one predefined rotation direction and to prevent the transmission of rotation of the output member in this predefined rotation direction to one or the other of the wheels. Each unidirectional transmission member includes two diametrically opposite teeth of asymmetrical shape and is connected to the output member in such a manner as to be constrained to rotate with it while being able to be moved between first and second extreme positions in a radial direction.

Abstract: A differential gear for watch movement may include a central shaft whereon first and second wheels are rotatably mounted, each of which is provided with a toothing arranged to mesh with a toothing of at least one satellite borne by a satellite carrier also mounted on the central shaft. The first and second wheels may be configured to engage first and second mobiles of the watch movement, the central shaft including a toothing configured to engage a third mobile of the watch movement. Further, the satellite carrier may be secured in rotation with the central shaft by a friction device comprising a tube having a first portion arranged bearing against the central shaft and at least one second portion arranged bearing against the satellite carrier. The tube may include a substantially cylindrical skirt, wherein at least one first tab is formed in such a way that it exerts a force having a radial component on the satellite carrier.

Abstract: A timepiece includes a casing having a casing interior having a viewer's side provided with a viewing opening, a base side provided with a sound aperture, and an annular surface surrounding the sound aperture. A membrane extending over the sound aperture closes the base side of the casing interior, the membrane having a circumferential region in sealed connection with the annular surface. A tensioning device maintains the membrane at a desired tension in the radial direction. A vibration generator arranged in the casing interior produces a sound whose frequency can be adjusted by adjusting the tension of the membrane.
