Abstract (en)

The dial has a visible surface of metallic appearance, comprising a morphology characteristic corresponding to that of mother-of-pearl. A mother-of-pearl sheet is subjected to a sandblasting operation, to give the morphology of mother-of-pearl, to the surface finish of the sheet. The surface is coated with a layer of metal such as pure yellow gold, grey platinum or pink gold/copper alloy. An independent claim is also included for a method for manufacturing a timepiece dial.
