A method for decorating the surface of a mechanical part including structuring, on the surface to be decorated, a masking layer having a thickness that is at least equal to the thickness of the decoration element to be produced; making, in the masking layer, at least one opening that coincides with the location on the surface to be decorated where the decoration element is to be produced, the opening having a contour that is identical to the contour of the decoration element and defining a volume with the mechanical part; filling the volume delimited by the masking layer and the surface to be decorated of with a filling material wherein the decoration elements are sought to be produced; and removing the masking layer.

Method for decorating a mechanical part

Method for producing an external horological element () which is a heterogeneous component, according to which a primary cavity () is produced in a structure (), only the periphery of this said primary cavity () is re-machined or laser machined, which primary cavity () is filled with a second material that is different in appearance from the first material in order to produce a primary insert (), where the bottom of this said primary cavity () is left rough before being filled with said second material, and, in the thickness of this primary insert (), a secondary cavity () is produced, which is filled with a third material that is different in appearance from the first material and/or from the second material in order to produce a secondary insert ().
