Abstract

A method for fabricating an external element or a timepiece dial from non-conductive material, by performing or repeating a basic cycle of making a base from a non-conductive, or ceramic, or glass. or sapphire substrate; dry coating the base with a first sacrificial protective metal layer; etching a decoration with an ultrashort pulse laser to a depth at least equal to the local thickness of the first layer; dry coating the decoration and the remaining part of the first layer with a second metal and/or coloured decorative treatment layer; chemically removing each first layer; and before or after chemical removal of each first layer, mechanically levelling on the upper level of the base the compound thus formed.
