摘要：
A method of manufacturing a ceramic element for a timepiece is provided, including forming a body made of oxide-based ceramic; exposing at least one portion of the external surface of the body to a reduction reaction, to remove oxygen atoms to a predetermined depth in order to make the at least one portion electrically conductive; depositing a metallic material starting from the at least one electrically conductive portion; and machining the body and/or the metallic material in order to provide the element with an aesthetic finish.
