The present invention relates to the production and the mechanical and / or optical functionalization method of the transparent clock components (1), in which the poly comprising a bottom surface (3) and mechanically and / or intermediate surface is optically functionalized with 7 methacrylate body (1,6) is formed; The body is, the joint 14 between the previous mold (9) in contact with the intermediate body (6A) or the body (16) defined by the complementary intermediate surface (7A) of the surface (10) of the mold (9) polymerizable material of the second transparent (6) coated with a layer which is formed by injection mold is a negative of the upper surface (2) of the part (1); The second material (6) is polymerized; The components (1) are separated from the flexible mold (9) by the deformation of the mold. By the insulation part (1) for the UV is improved hardness.
