An oscillating winding mass (1) of a movement of a timepiece, the oscillating winding mass (1) being intended to be mounted for rotation on an arbor of the movement, the mass (1) including a main element (2) conferring the overall form of the oscillating winding mass (1), a heavy part allowing oscillation of the mass (1) in response to the movement of the timepiece and to the force of gravity. The mass (1) includes a decorative element (3), for example a logo or initials, the decorative element (3) being fixed to the main element (2), the main element (2) including two superimposed parts (4, 5) connected one to the other, the decorative element (3) being held by at least one end (11) embedded in the material of the main element (2).
An oscillating winding mass (1) of a movement of a timepiece, said oscillating winding mass (1) being intended to be mounted for rotation on an arbor of the movement, said mass (1) comprising a main element (2) conferring the overall form of the oscillating winding mass (1) and comprising an attachment (6) for fixing on the movement, a heavy part allowing the oscillation of the mass (1) in response to the movement of the timepiece and to the force of gravity, and a decorative element (3) fixed to the main element (2) by at least one end (11) embedded in the material of the main element (2), the main element (2) comprising a through opening (9), the decorative element (3) being arranged at least partly in said opening (9).
A method for manufacturing an oscillating winding mass, said oscillating winding mass (1) being intended to be mounted for rotation on an arbor of the movement, said mass (1) comprising a main element (2) conferring the general form of the oscillating winding mass (1), a heavy part allowing the oscillation of the mass (1) in response to the movement of the timepiece and to the force of gravity, wherein the method comprises a first step of manufacture of a main element (2) of the mass (1) in two superimposable parts (4, 5), a second step of manufacturing a decorative element (3), for example a logo or initials, and a third step of assembling the main element (2) and the decorative element, (3) the decorative element (2) being held between the two parts (4, 5) by at least one end (11).
