Abstract
The present invention relates to a manufacturing process for a watch component (50) in composite material with a ceramic matrix comprising the following steps: depositing in a mould a succession of layers (10, 20, 30, 40) each comprising a ceramic powder (12), at least one layer (10; 10, 30; 10, 20, 30, 40) further including fibres (14) mixed with the ceramic powder (12), the fibres (14) being arranged randomly; performing a FAST/SPS sintering operation; demoulding the sintered watch component comprising the succession of layers (10, 20, 30, 40), and optionally machining the sintered component to the final dimensions of the watch component (50). The fibres (14) are visible on the surface of the watch component (50).
