A horology component (1) for a timepiece, including a first portion (10) and a second portion (20), the first portion (10) comprising one part that is at least partially transparent and at least partially superposed on top of the second portion (20), this second portion (20) taking the form of a massive portion comprising a material capable of emitting at least one emission light wave if excited by at least one excitation light wave, and the at least partially transparent part of the first portion allowing an emission light wave emitted by the second portion (20) to be transmitted at least partially toward the outside of the horology component so that the horology component exhibits at least a first appearance by day and at least one different second appearance by night where the first portion (10) is backlit by an emission light wave emitted by the second portion (20).

Provided is a timepiece including, in addition to a crystal, the following external elements: a back (2), a middle part (1), a dial (3), and two bracelet strands (30), at least one of these external elements includes a body formed of a first portion made of a first opaque material and of a second portion made of a second partially transparent or translucent material. The first material being integral with the second material and the timepiece also includes at least one light source (10) producing light which passes through the second portion made of a partially transparent or translucent ceramic material comprising zirconia.

The invention relates to a timepiece including, in addition to a crystal (34), the following external elements: a back (2), a middle (1), a dial (3) and two bracelet strands (30), at least one of these external elements comprising at least one part made of an at least partially transparent or translucent ceramic material, the timepiece further including at least two point light sources (10) releasing heat, each light source (10) being capable of being separately switched on/off and being disposed in or directly beneath said at least one external element comprising the ceramic material, each light source (10) producing light that passes through the ceramic material of said external element, and wherein each light source (10) is configured to produce localised light on a point or quasi-point area (40) of the ceramic material of the external element concerned, so as to produce localised illumination on said external element.

The present invention relates to a method for manufacturing a luminescent horological component for a portable object.

A bezel (1) for a timepiece, including an annular slot (2) with a bottom (20) and two walls (21, 22), wherein a ring made of a luminescent material (3) is disposed on the bottom, the ring (3) being topped by a second ring (4) made of a mineral material occupying the volume of the slot. The bezel (1) includes in each of the two walls (21, 22) a seal (5, 5′) cooperating with the second ring (4).

A method for manufacturing a luminescent timepiece component for a portable object includes producing a pre-mixture of a phosphorescent pigment in an amount of 10 to 40% by weight, a fluorescent pigment in an amount of 1 to 4% by weight and a plasticiser in a maximum amount of 10% by weight; mixing a polymer base with the pre-mixture and extruding a first time the mixture obtained to obtain a homogeneous polymer mixture; extruding a second time the polymer mixture to form a strip of a predetermined thickness; and cutting the strip to obtain the desired luminescent timepiece component.

The present invention relates to a timepiece component comprising on at least one part of its surface a coating formed of one or more layers of organic pigments.

The method makes it possible to produce a decorated component for a timepiece or piece of jewellery. This component provided with the decoration may be, for example, a watch hand. To produce said component, a base substrate is used and a micromachining operation is performed on or in the base substrate to obtain an upper part of the component, which is provided with the decoration. The decoration is produced through the thickness of the upper part and in a programmed pattern. Thereafter, the upper part is placed on a luminescent or colored substance to obtain the component.
