An applique for horology includes a visible upper surface and a lower surface for resting on a dial or a structure of a timepiece. The applique also includes at least one foot projecting from the lower surface for attachment to the dial or the structure. To manufacture the applique, in a first operation, a profile or bar is provided in which blanks of the feet and of the lower surface are machined prior to cutting the profile or bar in a second operation. Then, the upper surface is re-machined with at least one final diamond-polishing operation. During the first operation, at least two machining operations are performed in a cross so as to form a blank of each foot with a polygonal contour having facets.

Method for fabricating diamond-polished appliques for horology

A method for fabricating an applique for horology including a visible upper surface, and a lower surface from which protrudes at least one securing foot: a rough piece is made as a straight workpiece; this rough piece is deformed to form a blank so as to form an upper curve; this blank including this feet is machined; this blank is mounted on a tool having a support surface complementary to the lower surface of this blank, a recess for housing each foot, gripping means and/or an adhesive for securing each blank; the upper curve of this blank is machined with at least one final diamond-polishing operation to form this upper surface.
