1. A method of manufacturing at least one timepiece element to be mounted on a timepiece component, said method comprising:
forming a mould by assembling a first part, a second part, and a third part, the second part being positioned directly between the first part and the third part;
producing a blank of the timepiece element from an injection ovennoulding of injectable material into at least one cavity of the mould defined for development of the timepiece element to be manufactured, said cavity being defined by an association of at least one impression of the first part of the mould with the second part of said mould, said second part comprising a channel including an inlet orifice of the cavity for injecting said material into said cavity, the third part including an injection circuit extending through a thickness of the third part, the injection circuit being aligned with the channel such that the material travels through the injection circuit and the channel before reaching the inlet orifice of the cavity;
finishing the timepiece element comprising applying a coating on said blank of said timepiece element overmoulded on the second part, said applying comprising a phase of disassembling/withdrawing the first part from the second part; and
withdrawing the finished timepiece element from the second part comprising breaking an injection point connecting said timepiece element to the second part in preparation for the mounting thereof on the timepiece component.
