Timepiece display mechanism, for a watch, comprising a roller pivoting about a main axis and comprising flaps, each pivoting about a secondary axis parallel to the main axis and having two faces, first drive means for pivoting the roller about the main axis, and second drive means for pivoting a flap about its secondary axis, in a determined position of this secondary axis relative to the main axis, and which include, at each flap, a drive pinion cooperating with a control means to modify, in sequence or continuously, the position of the successive flaps of the same roller or to modify, on demand, the position of a specific flap.

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.
