Abstract
To fabricate an external timepiece element in which there is inserted at least one decoration, the decoration is formed of anterior and posterior parts respectively intended to emerge from the external element and to serve as a mechanism of anchoring the decoration in the external element. A master mold is provided, the master mold including a hollow pattern cavity matching dimensions of the anterior part of the decoration. The decoration is placed in the pattern cavity. The master mold is filled by the galvanic deposition of a metal. The external element obtained is removed from the master mold.
