Production of an applique for a timepiece dial

A method for producing an applique for a timepiece dial, the applique comprising at least two distinct portions made of a first material and a second material, respectively, the first and second materials being different, the applique comprising a lower surface by which the applique is intended to be fastened to the timepiece dial, an upper surface opposite the lower surface, and at least one side surface between the lower surface and the upper surface,

• the method comprising:
• in a first phase, forming at least a second blank made of the second material within or at least partially within a first blank made of the first material so as to obtain a blank of the applique for a timepiece dial, then
• in a second phase, machining each of the first blank and the second blank, so as to modify a shape and a surface state of each of the first and second blanks of the applique blank, and
• after the machining of each of the first blank and the second blank forming a cell, filling the cell with an adhesive, then routing the at least one applique blank from a second face of the plate, opposite to the first face, followed by detaching the timepiece dial applique from the plate by removing the adhesive,
• wherein the forming in the first phase comprises forming the first blank by:
• obtaining a flat plate made of the first material;
• and
• machining a first face of the plate so as to form at least the first blank,
• wherein the machining in the second phase comprises:
• routing the applique blank formed of the first blank made of the first material and the second blank made of the second material, the routing forming at least a portion of a contour of the applique blank and forming a cell in which the applique blank is arranged, and
• surfacing the applique blank formed of the first blank made of the first material and the second blank made of the second material, the surfacing making it possible to form (i) the upper surface comprising the two materials in a juxtaposed arrangement, and/or (ii) the side surface comprising the two materials in a juxtaposed arrangement.

An applique for a timepiece dial, comprising:

• a first portion made of the first material, and
• a second portion made of the second material,
• the first and second materials being different,
• a lower surface by which the applique is intended to be fastened to the timepiece dial,
• an upper surface opposite the lower surface, and
• at least one side surface between the lower surface and the upper surface,
• wherein the applique comprises at least one of the following:
• a fastening device capable of fastening the applique to the timepiece dial, the upper surface being intended to remain on a visible face of the timepiece dial, the upper surface having at least a part that is not parallel to the timepiece dial to which the applique is intended to be fastened, the upper surface part comprising the first and second materials in a juxtaposed arrangement,
• a side surface comprising the first and second materials in a juxtaposed arrangement, the side surface extending in a direction substantially perpendicular to the timepiece dial to which the applique is intended to be fastened,
• wherein the applique has been produced by a method comprising:
• in a first phase, forming at least a second blank made of the second material within or at least partially within a first blank made of the first material so as to obtain a blank of the applique, then
• in a second phase, machining each of the first blank and the second blank, so as to modify a shape and a surface state of each of the first and second blanks of the applique blank,
• wherein the machining in the second phase comprises:
• routing the applique blank formed of the first blank made of the first material and the second blank made of the second material, the routing forming at least a portion of a contour of the applique blank and forming a cell in which the applique blank is arranged, and
• surfacing the applique blank formed of the first blank made of the first material and the second blank made of the second material, the surfacing making it possible to form (i) the upper surface comprising the two materials in the juxtaposed arrangement, and/or (ii) the side surface comprising the two materials in the juxtaposed arrangement.
