Abstract: A process for producing a part provided with an external element includes: providing an electrically conductive substrate having an upper surface and a raised pattern with a crest on the upper surface; depositing an electrically insulating layer onto the upper surface around the pattern to a thickness less than or equal to the distance between the crest and the upper surface; depositing a metal layer onto the crest by galvanic growth so that the metal layer partly rests on the insulating layer; dissolving the insulating layer; covering an assembly including the substrate and the metal layer with a mass of a base material of the part to form an imprint; separating the mass and the metal layer from the substrate, the mass then exhibiting an external element formed by a recess, the shape of which corresponds to the imprint and the base of which interfaces with the metal layer.

Abstract: A balance for timepieces includes a rim, a hub, and at least one arm connecting the hub to the rim. At least one portion of the balance is made of an at least partially amorphous metal alloy. The at least partially amorphous metal alloy is based on an element chosen from the group consisting of platinum, zirconium and titanium, and has a coefficient of thermal expansion comprised between 7 ppm/° C. and 12 ppm/° C. The balance can be manufactured by moulding. A resonator can include such a balance and a monocrystalline quartz balance spring.

Abstract: A process for producing a metal alloy balance wheel by molding, the process including the following steps: a) making a mold in the negative shape of the balance wheel, b) getting hold of a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature, c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel, d) cooling the metal alloy to obtain a balance wheel made of the metal alloy, e) releasing the balance wheel obtained in step d) from its mold.

Abstract: A method of decorating an element. This method includes the following steps: taking the element (1, 11, 21, 31), the element including anchoring for improving the securing of the decoration (5) to the element; making a mask (4) of the desired thickness of the decorations (5), and having at least one opening (4′); placing the at least one opening in the mask (4) against the place to be decorated so as to form at least one mould (4′, 6, 6′, 6″,100); filling the at least one mould with an at least partially amorphous material via hot forming; and removing the mask (4).
