Abstract: A method for manufacturing a pivot bearing (1) for the pivoting of a timepiece component (2), in particular a pivot stone, includes:—boring (E1) a hole (10a) in a bearing blank (1a) along an axis (A1) intended for the pivoting of a timepiece component (2), this hole (10a) forming a start point (13a) of a first pivot zone (13) of the bearing (1), then—laser engraving (E2), in the blank (1a), in particular using a femtosecond laser, a second clearance zone (14) of the bearing (1), juxtaposed with the start point (13a) of a first pivot zone (13), this second clearance zone (14) of the bearing (1) opening at a first face (11a) of the bearing (1) blank (1a), then—removing material by wear (E3), in particular by olive-cutting, at the start point (13a) of the first pivot zone (13) of the bearing (1) and a boundary zone (14a) between the start point (13a) and the second clearance zone (14) of the bearing (1) in order to form a first pivot zone (13) and a second clearance zone (14) that are juxtaposed, connected to each other by a rounded connection.
