A method including obtaining an at least partially transparent object (), providing a mask () defining at least one opening () wherein the contour corresponds to a profile of the anti-counterfeit marking to be structured, the mask () covering a surface of the at least partially transparent object () at the areas not to be structured, structuring the anti-counterfeit marking by bombarding the at least partially transparent object () by an ion beam () through the at least one opening () of the mask (), the mechanical properties of the mask () being sufficient to prevent the ions of the ion beam () from etching the surface of the at least partially transparent object () at the areas where this surface is covered by the mask (), removing the mask (), and placing the at least partially transparent object () in a bath () at alkaline pH.

Method for structuring an anti-counterfeit marking in an at least partially transparent object and at least partially transparent object comprising an anti-counterfeit marking

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.

Method for manufacturing decorative parts

The present invention relates to a method for manufacturing a part comprising at least one three-dimensional metallised pattern overlying a local enamel underlayer.

Method for manufacturing a part comprising at least one three-dimensional metallised pattern

A method for brazing a first ceramic component and a second metal alloy component, to make a structural or external timepiece element, a zirconia-based ceramic is chosen for the first component and a titanium alloy for the second component, a first recess is made inside the first component, set back from a first surface in a junction area with a second surface of the second component, braze material is deposited on this first surface and inside each recess, the second surface is positioned in alignment with the first surface to form an assembly, this assembly is heated in a controlled atmosphere to above the melting temperature of the braze material, in order to form the braze in the junction area.
