Abstract
The invention relates to a pivot arbor (1) for a timepiece movement comprising at least one pivot (3) made of a first non-magnetic metal material (4) at one of the ends thereof in order to limit the sensitivity thereof to magnetic fields. At least the outer surface of said pivot (3) is coated with a layer (5) of a second material selected from the group comprising Ni and NiP, and preferably chemical NiP. The invention concerns the field of timepiece movements.
Claims25
A pivot arbor for a timepiece movement comprising at least one pivot made of a first non-magnetic metal material at at least one of the ends thereof in order to limit the sensitivity thereof to magnetic fields, wherein at least the outer surface of said pivot is coated with a layer of a second material selected from the group consisting of Ni and NiP.
A movement for a timepiece comprising a pivot arbor comprising at least one pivot made of a first non-magnetic metal material at at least one of the ends thereof in order to limit the sensitivity thereof to magnetic fields, wherein at least the outer surface of said pivot is coated with a layer of a second material selected from the group consisting of Ni and NiP.
A Movement for a timepiece wherein the movement comprises a balance staff, a pallet staff and/or an escape pinion comprising a pivot arbor comprising at least one pivot made of a first non-magnetic metal material at at least one of the ends thereof in order to limit the sensitivity thereof to magnetic fields, at least the outer surface of said pivot being coated with a layer of a second material selected from the group consisting of Ni and NiP.
A method for fabricating a pivot arbor for a timepiece movement comprising the following steps:
- a) forming a pivot arbor comprising at least one pivot made of a first non-magnetic metal material at one of the ends thereof in order to limit the sensitivity thereof to magnetic fields;
- b) depositing a layer of a second material on at least the outer surface of said pivot, said second material being selected from the group consisting of Ni and NiP.
