Economical timepiece display component

A method of manufacturing a timepiece display or hand-fitting component including at least one visible surface, wherein the following steps are performed in succession:

• choosing a first material shapeable by deformation, and/or machining and/or injection and/or casting and/or galvanic growth, in order to make a workpiece;
• making a workpiece in said first material,
• choosing a second material to make the visible surface, wherein the second material is an amorphous metal alloy or has a nanocrystalline structure or includes nickel or nickel-phosphorus, or which is a pure metal or an alloy of gold and/or silver and/or copper and/or rhodium and/or titanium and/or aluminium;
• coating said workpiece, at least on a position of the visible surface, with a thick layer, of an initial thickness greater than or equal to 20 micrometres, of said second material;
• diamond tool machining the visible surface which is intended to remain visible, removing at least part of said, thick layer of said second material,
• wherein, during said diamond tool machining, at least the visible surface intended to remain visible is diamond machined, removing part of said thick layer of said second material, with a surface condition comprised between 2 nm Ra and 50 nm Ra, and
• wherein at least another part of the thick layer remains at the initial thickness after the diamond tool machining.
