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.
