Abstract: The invention relates to a method for producing a timepiece component, characterised in that it comprises an electrodeposition step consisting in depositing an alloy on a substrate, forming at least one flank of the timepiece component with a thickness greater than or equal to 50 ?m, said electrodeposition step being carried out with an electrolyte solution comprising a nickel-containing compound and a second nickel-free compound at concentrations such that the alloy obtained comprises between 91 and 99.8 wt.-% nickel and between 0.2 and 6 wt.-%, or even between 0.2 and 4 wt.-%, of a second element from the second compound.
