A ceramic element destined to be fitted on a watch casing has some patterns on its visible surface. The patterns are fixed on the surface by a first fastening layer (3) of at least 100 nm covered with a second layer (4) from the group gold, silver, chromium nitride (CrN), nickel, platinum, titanium nitride (TiN), zirconium nitride (ZrN), palladium or their alloys with a thickness of at least 100 nm. An independent claim is also included for the fabrication of this ceramic element. |
