Abstract (en)

[origin: WO2022058160A1] Method for manufacturing a timepiece mobile, in which a substrate is produced with a first material comprising at least nickel and phosphorus, the substrate is shaped to the geometry of the mobile, and the substrate is galvanically or chemically coated, on at least one surface of the mobile substrate, with at least one second material which constitutes the peripheral layer of the mobile on the at least one surface of the mobile substrate, and which comprises at least nickel and which has less phosphorus than the first material, or which comprises nickel and lacks phosphorus.
