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.

An electronic watch may include a tactile switch and/or one or more sensors for detecting rotational and translational inputs. The watch may include a display configured to produce graphical outputs that may change in response to rotational inputs, translational inputs, and/or touch inputs received at the display. The watch include a crown positioned along an exterior of the watch enclosure and a shaft coupled to the crown and extending into the enclosure. The tactile switch and/or the one or more sensors may be used to detect rotational and/or translational inputs provided at the crown.

A push-piece winding button control device is for a portable object of small dimensions. This device includes a pivoting control stem axially movable between at least a transitory first position and a stable second position. The device further includes a position indexing plate arranged to be integral in translation with the control stem, while keeping the same orientation relative to the frame. The device also includes a cam follower arranged to cooperate with a longitudinal cam path formed in the position indexing plate. The cam path includes a recess defining the stable position of the control stem, and a ramp-shaped profile portion which rises from the recess towards the transitory position.
