Abstract: Method of manufacturing a watch component (10) for a timepiece, wherein it comprises a first stage of manufacturing a watch component (10) comprising a first surface (1), in which there is arranged at least one recess (20), that is to say a surface recessed from the first surface (1), and wherein it comprises a second finishing stage the watch component, leading to a change in the surface condition, more particularly the roughness, more particularly measured by the parameters Ra and/or Str, and/or the gloss, of the first surface (1) but not of the at least one recess (20) or of a portion exclusively of this at least one recess (20).

Abstract: The process for manufacturing a ceramic timepiece component includes:—manufacturing an intermediate component (E1) in the form of green body based on ceria-zirconia;—totally or partially debinding (E2) the intermediate component to obtain a debound intermediate component:—partially impregnating (E3) the debound intermediate component with at least one solution comprising at least one metal salt, on one portion only of its surface, to obtain an impregnated debound intermediate component:—sintering and thermally treating (E4) the impregnated debound intermediate component by performing at least one heat treatment under a reducing atmosphere (E42; E41′).
