摘要： A method for manufacturing a timepiece wheel, according to which a substrate is produced with a first material including at least nickel and phosphorus, the substrate is shaped to the geometry of the wheel, and a coating of the substrate is performed, galvanically and/or chemically, on at least one surface of the substrate of the wheel, with at least one second material, which constitutes the peripheral layer of the wheel at the at least one surface of the substrate of the wheel, and which includes at least nickel and which is poorer in phosphorus than the first material, or which includes nickel and is devoid of phosphorus.
