Timepiece display mobile component (1) comprising at least one resilient strip (4) returned to a display axis (DA), to cooperate in a friction drive with an arbor (2) of a drive mobile component (3) of a movement (100) or a mechanism, about the axis (DA), this mobile component (1) includes a flange (5) comprising, facing each resilient strip (4), an aperture (6) for the insertion and guidance of a manual or robotic tool to allow the tool to move the resilient strip (4) away from its rest position, and to insert the mobile component (1) on an arbor (2) when the resilient strip (4) is sufficiently far away to allow this mobile component to pass, and to ensure a constant friction value of all the resilient strips (4) on the arbor (2) when they are in frictional cooperation with the arbor (2) and when the tool is no longer in contact with the resilient strips (4).

According to a movement of the present disclosure, the prevention of the transmission of torque to a governor when excessive torque is generated and the prevention of the wasteful consumption of energy when the excessive torque is not generated are achieved. The movement includes a main spring which generates torque, a balance wheel, a gear train mechanism for transmitting the torque generated by the main spring to the balance wheel, and a spring seat for moving a second wheel, for example, of the gear train mechanism in a direction to reduce the transmission efficiency of the torque between the wheels of the gear train mechanism when the torque generated by the main spring is higher than a predetermined torque (Tmax).

The invention concerns a device for holding a wheel set of a timepiece movement comprising a lever, intended to be mounted to slide via guide means on the main plate of the timepiece movement between a first and a second position.

According to the invention, the lever comprises, at a first end, a locking beak intended to cooperate with means for holding the wheel set to hold and to guide the wheel set in rotation in the first position and to leave the wheel set free in the second position, the lever being arranged to be able to move in translation, between the first position, called the retracted position, and the second position, called the deployed position.

Timepiece wheel with play take-up, including a toothing, each tooth of which includes first and second half-teeth each including a part of the tooth profile, and movable with respect to each other against elastic return means, the wheel including, axially stacked, a first and a second half-wheel respectively carrying the first and second half-teeth and having limited rotational mobility with respect to each other, about the axis of this toothing, and against the elastic return means, the toothing of each half-wheel overhanging the other half-wheel, each half-wheel including hollows inside each of which is movable an opposite half-tooth, between two successive half-teeth.

A display system for a timepiece is disclosed. The system includes a mobile arranged to be driven by a drive source by first teeth provided on the mobile. The mobile includes second teeth including a teeth module of less than 0.05 mm, the second teeth being arranged so as to drive a display member either directly or indirectly.

A timepiece display device including a first display element and a second display element superimposed above a fixed part including a main bearing surface, this second display element is subjected to opposing forces exerted, on the one hand by lower return means which tend to bring the second display element closer to the first display element, and, on the other hand, by upper return mechanism which tends to move the second display element away from the first display element without contact between them or else by mechanical spacing device which includes a bearing surface providing a stop bearing function on a stop surface of the second display element, to limit the travel from the second display element to the first display element.

A mechanism for adjusting a timepiece bridge fixed to a structure, including, coaxial and able to move one with respect to the other by sliding and/or rotation on a common axis, and returned one towards the other by an elastic return or clamping means, a first component fixed to the structure and a second component fixed to the bridge, the first component including a first relief facing a second relief that the second component includes, the first relief and the second relief having variable cooperation depending on the relative angular position between the first component and the second component, each the particular relative angular position defining a particular distance between reference surfaces of the first component and the second component.

A retrograde display mechanism including a main plate and a rack pivoting on a first arbor about a first axis centring its toothing, and including a sensing element following a cam pivoting on a second arbor about a second axis, the position of the first pivot axis and/or of the second pivot axis is adjustable with respect to the main plate with an adjustment plate carrying the first arbor and/or respectively the second arbor, and movable with at least one degree of freedom with respect to the main plate whose position with respect to the main plate is adjustable by an adjustment control device or an eccentric screw secured to the main plate and cooperating with a notch in the adjustment plate, or vice versa.

A correction mechanism for a function of a movement for a timepiece, notably a display function, including a corrector, and at least one clockwork part, notably a gear wheel, in which the clockwork part can be driven by a movement cooperating with a flexible transmission end of a movement.
