A timepiece component for a timepiece movement and notably a pivot arbor of a regulating member of a mechanical timepiece movement, made of an alloy containing by weight: between 25% and 55% of palladium, between 25% and 55% of silver, between 10% and 30% of copper, between 0.5% and 5% of zinc, gold and platinum with a total percentage of these two elements comprised between 15% and 25%, between 0% and 1% of one or more elements chosen from among boron and nickel, between 0% and 3% of one or more elements chosen from among rhenium and ruthenium, no more than 0.1% of one or more elements chosen from among iridium, osmium and rhodium, and no more than 0.2% of other impurities, the respective quantities of the components being such that, added together, they do not exceed 100%.

The present application describes a laser turning system (1) for producing a timepiece component, the system including a rotary spindle (3) for moving a bar of material (50) and a galvanometric scanner (12) capable of emitting a femtosecond laser beam scanning a generating profile of the component to be machined in the bar of material (50).

A support system (1) for a horological component (9), in particular for a horological component comprising a surface (91) generated by revolution and/or an axis (A9), includes a positioning device (2), in particular a centering device, for the horological component (9) in relation to an axis (A) of the system, and a holding device (3) for the horological component (9), the positioning device and holding device being independent and/or different and/or distinct.

A geometric inspection device for horological mobile components, including a headstock bearing a first spindle defining a first axis of rotation and a tailstock defining a second axis of rotation, on a common sole relative to which the headstock or the tailstock can move along a common direction parallel with the first axis of rotation. The device includes interchangeable micro-centering devices, at least one of the first spindle and the second spindle includes receiving means arranged to coaxially house a removable centering device, and at least one of the headstock and the tail stock includes pulling means arranged to pull without contact a micro-centering device axially along a common direction, opposite a space separating the headstock and the tailstock.
