Abstract
A method for manufacturing a pivot bearing () for the pivoting of a timepiece component (), in particular a pivot stone, includes:—boring (E) a hole () in a bearing blank () along an axis (A) intended for the pivoting of a timepiece component (), this hole () forming a start point () of a first pivot zone () of the bearing (), then—laser engraving (E), in the blank (), in particular using a femtosecond laser, a second clearance zone () of the bearing (), juxtaposed with the start point () of a first pivot zone (), this second clearance zone () of the bearing () opening at a first face () of the bearing () blank (), then—removing material by wear (E), in particular by olive-cutting, at the start point () of the first pivot zone () of the bearing () and a boundary zone () between the start point () and the second clearance zone () of the bearing () in order to form a first pivot zone () and a second clearance zone () that are juxtaposed, connected to each other by a rounded connection.
