Abstract: The invention relates to a timepiece component made of composite material including at least one reinforcement and one matrix, the reinforcement having a three-dimensional honeycomb structure with a plurality of cells into which the matrix is injected. The invention also concerns a method for manufacturing such a timepiece component.

Abstract: A decorative item made from a moulded material having a density of between 2 and 7 g/cm3, wherein the moulded material includes by weight: 60 to 90% of a metallic or ceramic material having a density higher than or equal to 5 g/cm3, 10 to 32% of a plastic material including a thermoplastic resin and a coupling agent, 0 to 8% of a reinforcement, 0 to 3% of a pigment. Also, a method of manufacturing this decorative item by injection moulding.

Abstract: A method of manufacturing an inlaid ceramic element for a timepiece including: a) forming a ceramic or cermet body; b) etching at least one recess in one face of the ceramic or cermet body, each at least one recess forming a pattern cavity for a decoration; c) changing a surface state of a bottom of the at least one recess to increase contact surface thereof; d) filling the at least one recess with a composite ceramic to form the decoration; e) flattening the composite ceramic so that the composite ceramic remains only in a hollow of the at least one recess.

Abstract: The present invention concerns an external timepiece element including a frame made of a first material, said external element further including at least one pressure or altitude sensor, characterized in that said pressure or altitude sensor is formed of at least one disc or plate, said disc or plate being formed of or coated with a binder and a piezochromic pigment, said piezochromic pigment being selected to react at a specific pressure, so that said pigment changes from a first colour to a second colour when said specific pressure is reached.

Abstract: A method for fabricating a part with relief, wherein portions in relief are at least partially coated with a decorative layer. The method a) forms the body of the part; b) selectively alters the surface state of the body of the part to change the adherence thereof locally relative to the decorative layer; c) directly deposits the decorative layer over the entire body; d) removes the portions of the deposited layer which have not adhered to the body of the part. The method can be utilized in decorating timepieces.
