Abstract: A horological component including a substrate and at least one first decoration component including at least one first photoluminescent material configured to procure a phosphorescent appearance. The horological component includes a second decoration component including at least one second material, the second material being metallic and configured to procure a metallic appearance, or variochromic and configured to procure a color that varies under the effect of a stimulus, the first decoration component and the second decoration component being arranged relative to one another on the substrate to form a decoration having a metallic appearance or a color that varies under the effect of a stimulus when the horological component is exposed to light and a phosphorescent appearance when the horological component is in the dark. A timepiece can include such a horological component.

Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ?E in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.

Abstract: A component intended for internal parts or the movement of a timepiece or piece of jewellery includes a substrate coated at least partially with a black coat including aluminium oxide.

Abstract: A component and method of making the internal parts or movement for a timepiece or piece of jewelry that includes a substrate partially coated with a black layer and decorated with at least one stone, said black layer including carbon nanotubes or aluminum oxide, said substrate being at least devoid of the black layer on the portion facing the stone.

Abstract: A decorative item including an element made at least partly of a metallic, polymeric or ceramic based material and including a face visible to an observer, at least one light source external or internal to the element, the decorative item further includes at least one optical fibre embedded in the material of the element, the optical fibre serving as a guide for the light from the light source in order to produce, during use, a light effect on the visible face of the element. A method for manufacturing the decorative item is also disclosed.

Abstract: A piece, in particular for jewellery or timepieces, is made of a material comprising a synthetic matrix loaded with particles of a precious or semi-precious stone. The particles have a particle size d90 between 50 ?m and 2 mm, preferably between 100 ?m and 1 mm, and more preferably between 150 ?m and 500 ?m.

Abstract: The striking or musical watch includes a watch case having a case middle and a back attached to the case middle in a sealed manner and in a detachable manner, a glass closing the case in a sealed manner, a watch movement or a watch electronic module retained in the interior of the watch case and equipped with a sonic vibration generator to be activated during specific periods in order to produce a sound or music. The watch includes at least one acoustic radiation membrane made at least in part of wood or a wood composite material and attached to a part of the case in order to radiate the sound produced by the sonic vibration generator towards the exterior of the case.
