Abstract

The invention relates to a method for forming a transparent timepiece component (1) comprising upper (2) and lower (3) surfaces in which: a polymerisable transparent material (5) is selected; a flexible female mould (9) is applied to a plate (15) wherein one contact surface (10) of the mould is the negative of the above mentioned lower surface (3) and is bordered by a rim (11) said mould (9) comprising a capillary network (14); a cavity (17) is formed by means of the sealed abutment of the rim (11) against a plate (6) of which one contact surface (7) is the negative of the above mentioned upper surface (2); the cavity (17) is filled with material (5) that is injected through the capillary network (14); the material (5) is polymerised in order to obtain a rigid component (1); and the component (1) is detached from the plates by deforming the flexible mould (9). Hardness is enhanced by insulating the component (1) against UV.
