Abstract (en)
[origin: CN107632507A] The invention relates to a pivot axis (1) for a watch movement. The pivot axis includes at least one pivot (3), which is made of a first non-magnetic metal material (4), at at least one of its ends inorder to limit its sensitivity to magnetic fields, at least the surface external of said pivot (3) being covered with a first layer (5) of a second material selected from the group comprising Ni, NiBand NiP, and preferably NiP chemical. At least the first layer (5) of the second material is at least partially covered with a second layer (6) of a third material selected from the group consistingof gold, silver, copper, platinum, rhodium, palladium and their alloys. The invention relates to the field of watch movements.
