A carbon fiber watch case includes a main body structure and a conductive structure. The main body structure has an inner surface and an outer surface. The conductive structure has a first contact on the inner surface and a second contact on the outer surface to electrically connect the inner surface and the outer surface of the carbon fiber watch case. The main body structure includes a braided body and a polymer body. The braided body includes a carbon fiber, and the braided body has a network-like structure. The polymer body at least fills a gap of the network-like structure of the braided body so that the braided body and the conductive structure form an integrated structure.

Method for forming a transparent timepiece component including top and bottom surfaces: a transparent polymerizable material is chosen; there is applied to a plate a flexible female mold including a capillary network and having a contact surface which is the negative of the bottom surface, bordered by an edge; a cavity is delimited by the sealed juxtaposition of the edge with a plate having a contact surface which is the negative of the top surface; the material is injected through the capillary network to fill the cavity; the material is polymerized to obtain a rigid component; the component is removed from the plates by the deformation of this flexible mold. Hardness is improved by the UV exposition of this component.

A method for producing a composite timepiece component, wherein, in a first step, a base and a first material are provided; in a second step, the base is positioned on an additive manufacturing device; in a third step, a first raised portion made of the first material is grown by additive manufacturing on one side of the base; in a fourth step, the development of the first raised portion is verified, the third and fourth steps are repeated iteratively until the first raised portion is seen and verified to have developed beyond a setpoint value, and additive manufacturing is stopped when this development exceeds this setpoint value; optionally, a second raised portion made of a second material is grown by additive manufacturing on one side of the base and/or on the first raised portion.

Method for manufacturing by photolithography a resin multilayer mould (10; 10) including a cavity (11; 11) provided with an inlet (110; 110) for the manufacture of a horological component, including producing at least two resin layers of the mould (10; 10), by producing a first resin layer (C10; C20) having a first through-opening or open opening (111; 111) oriented in the direction of the inlet (110; 110) of the mould to delimit a first volume of the cavity (11; 11) of the mould (10, 10), and producing a second resin layer (C20; C30) including a rigid film and having a second through-opening (112; 112) that delimits a second volume of the cavity (11; 11) of the mould (10, 10) and is at least partly superposed on the first through-opening or open opening (111; 111), the second resin layer partly covering that same first through-opening or open opening (111; 111).

A system for producing at least one three-dimensional element on a visible face of an external part element of a timepiece implementing this process, the system including a mould formed by the reversible assembly of a first part and a second part configured to receive a support plate of the external part element, the mould including at least one cavity formed by associating the first part including at least one impression with the visible face of the external part element, each cavity helping produce a blank of the three-dimensional element from an over-moulding by injecting injectable material onto the visible face, and a device for applying a coating onto the blank over-moulded on the visible face of the external part element helping finalise this blank of the three-dimensional element.

A process for manufacturing a watch dial including at least one pattern on a visible face of the dial, the process including: a step of designing a support plate including a dial blank, this step including producing several through holes in the thickness of the body of a support plate, the holes delimiting in such a plate the edge of the dial blank, and a step of producing at least one pattern on a visible face of the dial blank during which step the following is performed: an arrangement of this support plate including the external part element in a mould, and a construction of a blank of each pattern on the visible face of the dial blank, as well as a finalisation of the blank of the pattern.

A method for manufacturing a dial bauche of a measuring apparatus mounted in a rest plate (3a, 3b) including: forming, in an enclosure of the mould (2), a central cavity (9a) and peripheral cavities (9b) defined around this central cavity (9a), the step (34) providing for fitting (35) the rest plate (3a, 3b) in this enclosure formed by a reversible assembly of first and second parts (7a, 7b) of this mould (2); designing the dial bauche (4a, 4b) in the central cavity (9a) and attachment elements (10) in the peripheral cavities (9b), and unmoulding the rest plate (3a, 3b) from the mould (2), the plate including the dial bauche (4a, 4b) and the designed attachment elements (10), ensuring the attachment of the bauche (4a, 4b) in the plate (3a, 3b).
