Abstract
A method for fabricating a timepiece component made of conductive material includes: making a base from conductive material; coating the base with a first layer of sacrificial metal protection material; etching a recessed decoration mechanically or with a laser; coating the first recessed decoration and the remaining part of the first layer with a second metal and/or coloured decorative treatment layer; and removing each first sacrificial metal protection layer by chemical devices, to obtain a blank including a first decoration formed by the remaining part of the second layer.
