  • Patent number: 9411314
    Abstract: An integral assembly of a single or double hairspring and an unsplit collet including two portions opposite one another for receiving the balance staff, one portion including one of the bearing surfaces (2 or 3) for the balance staff and a point (10, 11) for attaching the hairspring, and the other portion including another bearing surface (4, 5 or 14) for the balance staff, the two portions being connected together by two linking portions that are less rigid than the receiving portions so as to be capable of elastically deforming during the fitting of a balance staff. According to another aspect, the invention also relates to an integral assembly of a hairspring and a collet, including at least two stages, as well as to a method for manufacturing such an assembly.

  • Publication number: 20150309474
    Abstract: The manufacturing process produces a part (10), from a micromachinable material, the part (10) forming a blank of the timepiece component and comprising at least one surface having an initial roughness. It comprises a step of mechanical strengthening treatment of the part in an etching fluid intended to decrease the roughness of said surface. For example, a substrate of said micromachinable material is provided; the substrate is at least partially covered with a protective coating containing at least one aperture; the substrate is etched through the aperture in the protective coating and an etched surface is thus obtained; the mechanical strengthening treatment is applied to said etched surface through the aperture in the protective coating; and then the protective coating is removed. The etching fluid may be a plasma or a liquid chemical etchant.
