Abstract
A method for mechanical and/or optical functionalization of a transparent timepiece component, including: forming a body of methyl polymethacrylate, including a bottom surface and a mechanical and/or optically functionalized intermediate surface; coating the body with a layer made by injecting a second transparent polymerizable material into a cavity between a mold and the body or an intermediate body delimited by a complementary intermediate surface of a contact surface of a preceding mold, the last mold being the negative of the top surface of the component; polymerizing the second material therein; removing the component from the flexible mold by deformation of the mold. Hardness can be improved by UV irradiation of a component.
