A holding member for fixing a timepiece component on support elements of different cross section includes an opening into which each support element can be inserted, the holding member having structural elements together forming a body configured to ensure mounting of each support element in the opening. Each of the structural elements includes a first structural sub-element and a second structural sub-element, the first structural sub-element including a volume of material greater than a volume of material constituting the second structural sub-element. The holding member includes a connecting portion ensuring the mounting of each of the support elements in the holding member, the portion being defined on an inner face of the first structural sub-element.

An elastic retaining member is for attaching a horological component to a support element. The retaining includes an opening into which the support element is capable of being inserted. The retaining member also includes rigid arms and elastic arms defined between the connection zones of the retaining member. The arms contribute to procuring elastic gripping of the support element in the opening, each rigid arm being provided with a single convex contact zone of the retaining member capable of engaging with a corresponding convex contact portion of the support element.

An elastic retaining member for fixing a timepiece component on a support element includes an opening into which the support element can be inserted, and rigid arms and elastic arms defined between connection areas of the member. The rigid arms and the elastic arms are configured to ensure elastic clamping of the support element in the opening, each of the rigid arms being provided with a single flat contact area and configured to cooperate with a corresponding convex contact portion of the support element.

A balance for a horological movement, including rigid parts including a hub defining the pivot axis of the balance, a felloe sector, at least one arm connecting the felloe sector to the hub, and including a slot for receiving and gripping an inertia-block in position, the slot opening into a housing delimited on the one hand by a rigid part of the balance, and on the other hand an elastic arm including a first end integral with a rigid part of the balance, and a second free distal end. The elastic arm has a hook-shaped body, the free distal end of the hook being parallel to a part of the balance having a rigidity greater than or equal to that of the elastic arm.

Timepiece balance

A balance for a horological movement, including rigid parts constituted by a hub defining the pivot axis of the balance, at least one felloe sector, at least one arm connecting the at least one felloe sector to said hub, and including a slot for receiving and gripping in position an inertia-block, the slot opening into a housing delimited on the one hand by a rigid part of the balance, and on the other hand an elastic arm including a first end integral with a rigid part of the balance, and a second free distal end. The elastic arm can have a body of a non-constant section, a part of the body having a greater thickness than the rest of the elastic arm so as to have a larger volume of material under stress and store a maximum of elastic energy.

Watch component

A shock absorber bearing for an arbor of a timepiece wheel set, particularly for a balance staff. The bearing includes a bearing assembly including a housing, a bearing support arranged inside the housing and including an external centring wall, a pivot bearing mounted on the bearing support for receiving a pivot of a wheel set arbor and an elastic support arrangement for the wheel set arbor pivot. The shock absorber bearing further includes a device for recentring play. This device for recentring play includes, on the one hand, a first part including a centring element having an internal centring wall in which is arranged the external centring wall of the bearing support, and on the other hand, a second part resting on the bearing assembly and arranged to have a return effect on the first part.
