Patent number: 12669783Abstract: A method is for manufacturing a part including a support provided with at least one hollow filled with an aesthetic element forming a decoration on a face of the part intended to be visible. The method includes providing the support provided with the at least one hollow and providing a preform intended to form the aesthetic element of the part, and inlaying by pressing the preform into the at least one hollow of the support. The preform is made of a crystalline aluminium alloy. The inlaying is carried out at a temperature between the solidus temperature and the liquidus temperature of the crystalline aluminium alloy.Type: GrantFiled: June 26, 2019Date of Patent: June 30, 2026Assignee: Comadur SAInventors: Johan Romand, Damien Le Boudouil, Nicolas Aubry, Pierry Vuille, Alexandre Netuschill

Publication number: 20260177981Abstract: A decorated piece including a substrate (1) with a surface (1a) defining a first part with a positive and/or negative relief (2) relative to the plane of the surface (1a) and a second part extending in the plane of the surface (1a), the first or second parts forming a decoration (4), wherein the first part is formed from the substrate (1) made of an amorphous zirconium-based metallic alloy and in that the second part is formed from a ceramic layer (3) deposited on the substrate (1) or, conversely, in that the first part is formed from the ceramic layer (3) deposited on the substrate (1) and in that the second part is formed of the substrate (1) made of the amorphous zirconium-based metallic alloy. Also, a method for manufacturing the decorated piece.Type: ApplicationFiled: December 8, 2025Publication date: June 25, 2026Applicant: Comadur SAInventors: Pierry VUILLE, Johan ROMAND

Publication number: 20250326248Abstract: A method for manufacturing an item (1) comprising a through-decoration (2) forming a so-called backlit plique-à-jour enamel, the method including obtaining a blank (5); removing part of the blank (5) from the inner face (5b) of the blank (5) to produce a decoration (2a) that does not pass through to the outer face (5a); depositing, from the inner face (5b), one or more layers of enamel (3) within the non-through decoration (2a); depositing, from the inner face (5b), a layer of luminescent material (4) on the enamel (3); depositing a protective layer (6) on the layer of luminescent material (4); and machining the outer face (5a) to reveal the enamel. Also, the related item.Type: ApplicationFiled: March 7, 2025Publication date: October 23, 2025Applicant: Comadur SAInventor: Johan ROMAND

Publication number: 20250328110Abstract: A method for manufacturing an item (1) including a through-decoration (2) filled with an enamel (3) to form a plique-à-jour enamel. The method includes: obtaining a blank (5) defined with an upper face (5a) and a lower face (5b) opposite the upper face (5a); removing part of the blank (5) from the upper face (5a) to produce a decoration (2a) that does not pass through to the lower face (5b) or, alternatively, in the previous step, obtaining said blank (5) directly with the non-through decoration (2a); depositing one or more layers of enamel (3) within the non-through decoration (2a) and firing the enamel (3) after each 10 layer has been deposited; machining, preferably by grinding, the lower face (5b) to reveal the enamel (3) and thus produce the item (1) with the through-decoration (2) filled with enamel (3).Type: ApplicationFiled: March 3, 2025Publication date: October 23, 2025Applicant: Comadur SAInventor: Johan ROMAND

Patent number: 12235610Abstract: An ornamental part, for example for a timepiece, jewellery or telephone, in particular a watch case middle, and its manufacturing method, the part at least partly including a hard material having a Vickers hardness greater than 1000 HV, the method including the following main steps: a step of producing a precursor from a mixture of at least one powder material with a binder, a step of injecting the precursor into a mould in order to form a green body, a step of sintering the green body in order to form a body of the future part from the hard material, and a step of depositing a polymer material coating on one face of the part, the deposition being carried out by moulding on the body, in particular by injection into a mould, the coating and the hard material being inseparable.Type: GrantFiled: May 14, 2021Date of Patent: February 25, 2025Assignee: Comadur SAInventors: Pierry Vuille, Denis Bubendorf, Paulo Arede, Johan Romand

Patent number: 11914331Abstract: A method is for manufacturing a part including a support made of an electrically non-conductive material, the support being provided with at least one recess filled with an aesthetic element made of an electrically conductive material, and the aesthetic element forms a decoration on a side of the part that is intended to be visible. The method includes inlaying by pressing a preform intended to form the aesthetic element into the at least one recess of the support, and treating the surface of the aesthetic element. The at least one recess opens in one or more places onto a side of the part that is intended to be non-visible, to respectively form one or more contact points for carrying current across the aesthetic element during the surface treatment.Type: GrantFiled: June 18, 2019Date of Patent: February 27, 2024Assignee: Comadur SAInventors: Johan Romand, Damien Le Boudouil, Nicolas Aubry, Pierry Vuille, Alexandre Netuschill

Publication number: 20220192326Abstract: A part (21), in particular a wristlet, including at least two sets (1) of elements (3, 5, 7), in particular links, assembled together. The securing between the elements (3, 5, 7) within a set and between sets is implemented via a gluing (15) rather than by a screwing. Also, a related method of manufacturing the part (21).Type: ApplicationFiled: October 4, 2021Publication date: June 23, 2022Applicant: Comadur SAInventors: Paulo AREDE, Pierry VUILLE, Johan ROMAND, Maxime DOLE
