A moving mechanism for a decorative element of a timepiece, the decorative element including at least two decorative faces disposed around an arbor defining the axis of the decorative element. The moving mechanism includes a circular drive element arranged to be rotatable about a central axis and including an aperture arranged to reveal one of the decorative faces of the decorative element and inside which said decorative element is mounted to rotate about its arbor. The moving mechanism also includes first device for driving the decorative element in rotation about its arbor mounted on the circular drive element and arranged to cooperate with fixed actuation means provided in the periphery of the circular drive element, such that the decorative element rotates about its arbor to successively display its decorative faces in the aperture of the circular drive element while rotating about the central axis.

A device for displaying at least one time-related magnitude including a timepiece movement including at least one time base and at least one energy source which extend in a first same plane, and at least one roller pivotably mounted about an axis of rotation A and which extends in a second plane parallel to the first plane, at least one roller including a display strip arranged on an outer periphery and on which at least one indication of the time-related magnitude is inscribed, the timepiece movement driving at least one roller in rotation about axis A via drive device which extend in the same second plane as at least one roller, at least one roller and the timepiece movement being centred on axis A.

Provided is a movement enabling easily providing an indicator position detection mechanism in a movement enabling changing the locations of an indicator by changing the configuration of a wheel train. The movement includes an indicator wheel to which an indicator is attached; a motor that drives the indicator wheel; a detection wheel train used to detect a position of the indicator; and a main plate to which the indicator wheel, the motor, and the detection wheel train are disposed. The main plate is configured to enable selectively disposing the indicator wheel to a first position or a second position that is different from the first position. The detection wheel train is disposed to the same position whether the indicator wheel is disposed to the first position or the second position.

A timepiece component including a shaft-like portion including at least one pivot about a pivot axis, at least the material forming this shaft-like portion is a non-magnetic alloy containing at least silver and palladium and having a Vickers hardness of more than 450 HV.

An adjustment mechanism for a timepiece display including an input wheel driving a control wheel controlling the position of a first display member, and including a differential mechanism which includes a drive wheel set retained by a jumper and pivotable via the first input wheel, to drive a planetary wheel meshing with the control wheel and pivoting off-centre with respect to a planetary wheel holder friction-mounted on a frame, the differential mechanism multiplying by a particular factor the rotation between one of the inputs and the output of the differential mechanism when the other input is stationary, and the planetary wheel holder includes manipulating device allowing a watch technician to release the friction to change the angular position of the planetary wheel and thus of the control wheel for correct indexing thereof with respect to another display member.
