Abstract

A pivot arbor for a timepiece movement includes a pivot made of a first non-magnetic metal material at at least one end in order to limit the sensitivity to magnetic fields. An outer surface of the pivot is coated with a first layer of a second material such as Ni, NiB, and/or NiP. The first layer of the second material is partially coated with a second layer of a third material selected from gold, silver, copper, platinum, rhodium, palladium and their alloys.
