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.

Horological component

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.

Decorative item with a light effect

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 &#x3bc;m and 2 mm, preferably between 100 &#x3bc;m and 1 mm, and more preferably between 150 &#x3bc;m and 500 &#x3bc;m.

Material for timepiece and jewellery

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.

Acoustic radiation membrane, and striking watch equipped with the acoustic membrane

The present invention concerns an electrochemical device comprising a cathode and an anode separated from each other by a separator, the battery further comprising two current collectors so that the anode and cathode are each arranged between the separator and a current collector, characterized in that at least one of the two current collectors is made of an at least partially amorphous material comprising at least one metallic element.

Amorphous metal current collector

A self-lubricating solid composite coating configured for an application to timepiece mechanisms, including particles of graphene and/or graphene oxide distributed in a metal matrix.
