Abstract: A process for manufacturing a timepiece component having a first step (E1) consisting in arranging a metal insert in an injection mold, one surface of said metal insert being at least partially coated with a primer, a second step (E2) of injecting an elastomer material into the injection mold in order to overmold the elastomer material over the metal insert, a third step (E3) of vulcanizing the elastomer material, wherein the temperature of the injection mold is variable, and a step (E31) of increasing the temperature of the injection mold between a first temperature at a first instant during the injection second step (E2), and a second temperature higher than the first temperature at a second instant, during the vulcanization third step (E3).

Abstract: A timepiece component (1) for a watch case, notably a bezel, comprising an axis (A), a first ring (10), a second ring (11) and a connecting element (12) for connecting the first and second rings, the connecting element being elastic and positioned between the first and second rings, the first ring and/or the second ring comprising an element (31) for retention on the rest of a watch case (200), particularly on a watch middle (4).

Abstract: The injection mold has a mold core including a first part and a second part. The parts are mobile relative to one another between a first injection position in which they are moved together to form an injection cavity permitting the injection of a material to form an injected part (50; 50?), and a second demolding position in which they are moved away from one another to permit the demolding of the injected part (50; 50?). The injection mold has at least one ejector designed to contribute to the demolding, and at least one movable intermediate plate (10; 10?, 20?), separate from the two parts of the mold core. The intermediate pate is arranged between the two parts of the mold core, and has at least one cutout (12; 12?, 22?) forming at least one part of the injection cavity of the injection mold.

Abstract: A ceramic powder for a ceramic component, in particular based on zirconia and/or alumina, in particular for a timepiece or jewelry piece. The powder includes at least one noble metal among platinum, rhodium, osmium, palladium, ruthenium and iridium, at a quantity of less than or equal to 5% by weight.

Abstract: A dial plate (1) for a timepiece is designed to be mounted on a connection ring (2), and has a first, lower surface (12) designed to be oriented towards the interior of a timepiece, an opposite second, upper surface (13) designed to be on view, and a third surface (11) connecting the first and second surfaces, forming a peripheral contour of the dial plate. The third, peripheral contour surface (11) includes a section which passes via a plane perpendicular to the second surface (13), this section having a first part (11a) extending from the first, lower surface (12) to the second, upper surface (13) of the dial plate (1), in a direction which is non-perpendicular to the first, lower surface (12).
