A method for manufacturing a timepiece component. The method includes: providing a timepiece component (1); breaking the timepiece component (1) into a plurality of pieces (10); and depositing the pieces (10) on a support (2) and creating a desired pattern to be reassembled having interstices (1). The support (2) is then transferred into a mould and a preform (3) is placed on the pieces (10). The assembly is then heated to a temperature higher than the vitreous transition temperature of the preform (3) and a force is applied on the preform to fill the interstices (11) and obtain a reassembled timepiece component (1'). The assembly is then cooled below the vitreous transition temperature of the preform (3) to form the reassembled timepiece component (1′) whereupon the timepiece component (1′) is machined to the required dimensions.

The main elementis connected to the mechanism of the movement, having parts, by an arbor about which it can turn. To this end, it comprises an attachmentfor fixing to the movement, which is for example formed by a small ring arranged in the openingof the ring of the main element. The attachmentis thus composed of the same material as the main element and is arranged in the same plane. By virtue of the attachment, the winding mass can make a circular movement about the arbor, when it oscillates.
