Claims5
A method for manufacturing an external part component of a watch, a fashion or jewellery item, comprising the following steps:
- polishing of a lower face of a substrate made of a transparent material;
- deposition of a base layer over all or part of the surface of an upper face of the substrate;
- localised removal of the base layer, in which a portion of said base layer is preserved over a first portion of the upper face of the substrate, said removal being carried out so as to form at least one pocket leading onto a second portion of the upper face of the substrate and so as to structure said second portion of the upper face of the substrate;
- and
- deposition of a secondary layer over the base layer and over the second portion of the upper face of the substrate.
