Abstract: 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).

Abstract: A method for manufacturing a timepiece component including successive steps of: providing a timepiece component (1); breaking the timepiece component (1) into a plurality of pieces (10); depositing the pieces (10) on a support (2) and creating a desired pattern to be reassembled, the pattern having interstices (1) between the various pieces (10) of the timepiece component (1); transferring the support (2) into a mould adapted by hot forming and placing a preform (3) on the pieces (10) of the timepiece component; heating the whole to a temperature higher than the vitreous transition temperature of the preform (3) and applying a force on the preform to fill the interstices (11) and obtain a reassembled timepiece component (1′); cooling the whole below the vitreous transition temperature of the preform (3) to form the reassembled timepiece component (1′); recovering the reassembled timepiece component (1′) and machining it to the required dimensions.
