A method for machining by laser ablation or by micro-milling a raised and/or hollow structure on an impression of an injection mould. A method for manufacturing a ceramic or cermet item by injection using the injection mould to produce an item, and in particular a watch bezel, decorated directly during the injection.

An external part element or component for a timepiece or piece of jewellery made with a fibre-reinforced polymer matrix composite material, this external part element including on at least one of the faces thereof at least one cavity wherein an insert made of metallic glass is housed. A method for manufacturing such an external part element is also described.

An electronic watch (1) including a case provided with a bezel (2) entirely or partially forming a tactile interface of the watch (1), the bezel (2) including an antenna circuit (10) of a communication module (6) and being provided with a body (5) including inner and outer faces (16, 17), the inner face (16) including a tactile control circuit (13) of a tactile control member (8) of this watch (1) and the outer face (17) including at least one tactile area (18a, 18b), the tactile control circuit (13) including at least one layer made of a conductive material forming an electrode (22) located beneath the at least one tactile area (18a, 18b).

The invention relates to a process for the production of a part provided with an external element comprising the following steps: provide an electrically conductive substrate having an upper surface and a pattern forming a recess in said upper surface deposit an electrically insulating layer into the pattern so that the insulating layer extends as far as the upper surface deposit a metal layer onto the upper surface of the substrate by galvanic growth so that at the end of this step the metal layer partly rests on the insulating layer dissolve the insulating layer cover an assembly comprising the substrate and the metal layer with a mass of a base material of the part, wherein the mass forms an imprint of the assembly separate the mass and the metal layer from the substrate, wherein the mass then exhibits an external element with a shape corresponding to the imprint of the pattern.

An annular rotating bezel system includes a rotating bezel, a toothed ring having a toothing provided with a plurality of teeth regularly distributed over an edge of the toothed ring, and a spring ring which extends in a plane in which it is capable of deforming elastically along a radius. The spring ring cooperates elastically with the toothed ring. The spring ring includes at least two lugs, each lug being configured to be elastically and radially engaged with the toothing of the toothed ring in at least one position of the bezel. At least two lugs are offset from each other by an offset angle, the or each offset angle between two successive lugs having a value different from an integer sub-multiple of 360 degrees, such that, in each position of the bezel, only one lug is elastically and radially engaged with the toothing of the toothed ring.

In a plan view in an axial direction of an indicating hand axle of a small second hand, three arrangement relationships described below are satisfied between a 10 o'clock side information display unit and an hour hand. According to a first arrangement relationship, respective numbers of a scale are disposed line-symmetrically with respect to a virtual straight line connecting a scale and the indicating hand axle to each other. According to a second arrangement relationship, the indicating hand axle is located at a position which does not overlap an indicating hand axle of the hour hand. According to a third arrangement relationship, a portion of a rotatable range of the hour hand overlaps a rotatable range of the small second hand, and does not overlap the scale.
