Abstract
A method for manufacturing an external component for watches or jewellery, especially a bracelet, includes the steps of: providing a substrate including a first face opposite to a second face and co-extrusion coating the first face and the second face of the substrate respectively with a first and a second band of synthetic material. The first band forms on the first face a transparent or translucent layer so that all or part of the substrate remains visible.
