    fig. 2 is a block diagram representing a watch comprising a clockwork movement, which comprises an oscillator, which incorporates such a mobile.
    Detailed description of the preferred embodiments [0013] Unless expressly specified otherwise, the compositions of the present description are mass.
    The invention relates to a timepiece component 1, in particular a mobile, which comprises a shafted part 2, which comprises at least one pivot 3 around a pivot axis D.
    With regard to the material of this shafted part, it is preferable that its Vickers hardness is between that of a copper-beryllium alloy, 380HV +/- 20, and that of a steel of type 20AP or the like. , 740HV +/- 30.

    In a particular embodiment, the component 1 is entirely non-magnetic.

More particularly still, the constituent material of each said added element 4, 40, is a non-magnetic alloy comprising at least silver and palladium of Vickers hardness greater than 450 HV.
    In a particular embodiment, the material constituting at least one, and more particularly of each added element 4, 40, is the same as that which constitutes the tree part 2.
    Alternatively, the material of at least one insert 4, 40 is a ceramic.

Copper has the effect of significantly increasing the hardness of the alloy.
    In an advantageous variant, this ternary non-magnetic alloy comprises, by mass, from 36% to 40% of palladium, from 38% to 42% of silver, from 19% to 23% of copper, the total silver of palladium and copper being less than or equal to 100%. Its Vickers hardness is between 450 HV and 510 HV, and more particularly between 470 HV and 490 HV. This alloy therefore constitutes an interesting material for any watch turning part, because its machinability is good, and its mechanical behavior is similar to that of steel. It is therefore particularly suitable for non-magnetic mobiles, or at least for non-magnetic mobile trees.
    In a particular variant, the alloy comprising at least silver and palladium is devoid of SVHC Substance of Very High Concern, also called substances of very high concern, according to Annex 3 of the Swiss OChim Ordinance on chemicals, and Annex 1.17 ORRChem (substances referred to in Annex XIV to Regulation (EC) No. 1907/2006 of the REACH Directive.

    In a variant for uses only internal to the watch, this non-magnetic alloy comprising at least silver and palladium comprises, by mass, from 0% to 1.0% of nickel, with a total mass of the components of the alloy equaled 100%.
    In a variant, this non-magnetic alloy comprising at least silver and palladium comprises, by mass, from 0% to 0.1% of zinc, with a total mass of the components of said alloy equal to 100%, for the obtaining higher strength and hardness, to obtain higher strength and hardness.
    In a variant, this non-magnetic alloy comprising at least silver and palladium comprises, by mass, from 0.01% to 0.03% of boron, with a total mass of the components of said alloy equal to 100%, for the obtaining higher strength and hardness.

    Thus, depending on the composition of the alloy, one can obtain a hardness close to 500 HV, or even greater than 500 HV.
    In a particular case, as visible in FIG. 1, this component 1 is a pendulum, and carries, on its shafted part 2, at least one serge 4 and at least one plate 40, bearing on support surfaces, respectively 50 and 60.
    The choice of alloy allows the production of a tigeronde very small diameter, in particular less than 70 micrometers.
    The invention also relates to a clock oscillator 100, comprising at least one such component 1.
    The invention also relates to a clockwork movement 200, comprising at least one such oscillator 100, and / or at least one such component 1.
    The invention also relates to a timepiece 1000 comprising at least one such movement 200, and / or at least one such oscillator 100, and / or at least one such component 1.
    More particularly, this timepiece 1000 is a watch.
    In short, the choice of a precious material, which can be titratable, for the production of a watchmaker's shaft, goes against prejudices relating to the rapid wear of precious alloys. The choice of an alloy comprising at least silver and palladium, among those described above, provides an astonishing response to the problem of wear, these alloys wear very little under normal conditions of use, while being non-magnetic as desired.
    Naturally, even if the above description has above all focused on the execution of mobiles with added elements, which make it possible to lower the material cost, the use of these alloys comprising at least money and palladium for monobloc mobiles is also quite possible.
    The invention provides a good answer to the still difficult problem of making non-magnetic mobiles of small diameter, in particular for oscillator mobiles, chronograph shafts, or the like.
