a first movement-blank (5) for pivoting the oscillator (100), a second pivot movement-blank (6) for pivoting the oscillator (100), a first element (7a, 7b) for positioning the first movement-blank (5) relative to the second movement-blank (6), the first positioning element (7a, 7b) being arranged and/or configured so as to position a spiral spring (1) relative to the first movement-blank (5) and/or relative to the second movement-blank (6) in a plane of the assembly (300) or of the movement (300).

Timepiece module (300) including a mobile (100), a first bridge (34), a second bridge (36), and a positioning system (150) for positioning the second bridge (36) on the first bridge (34), the positioning system (150) including positioning elements (31a, 31b) each one including a first positioning portion (312a, 312b) for positioning the first bridge (34), a second positioning portion (314a, 314b) for positioning the second bridge (36), and a third positioning portion (311a, 311b) able to position the positioning element (31a, 31b) relative to a frame (99), notably relative to a bridge or to a manipulate (4).

A mechanism for adjusting a timepiece bridge fixed to a structure, including, coaxial and able to move one with respect to the other by sliding and/or rotation on a common axis, and returned one towards the other by an elastic return or clamping means, a first component fixed to the structure and a second component fixed to the bridge, the first component including a first relief facing a second relief that the second component includes, the first relief and the second relief having variable cooperation depending on the relative angular position between the first component and the second component, each the particular relative angular position defining a particular distance between reference surfaces of the first component and the second component.

A device for adjusting a shake and more particularly a bar (100) for a balance (210) configured to be fastened and positioned on a bottom plate (200) by means of at least one fastening member (205). The bar (100) includes a reception opening (111) configured to receive a balance (210) and at least one plate (110) configured to be moved so as to adjust the distance between the at least one plate (110) and the bottom plate (200), at least one lever arm (120) configured to move the at least one plate (110) and at least one foot (130) configured to be in contact with the bottom plate (200) so as to make a mechanical connection and to move the at least one plate (110).

The hairspring (1; 1) has a spring blade (11; 11) and a connecting member (12; 12) for fastening the hairspring (1; 1) to a frame (5, 6, 8), the connecting member including first (13a; 13a) and second (13b; 13b) fastening element, a first arm (121; 121) connecting the first fastening element (13a; 13a) to the second fastening element (13b; 13b), and a second arm (122; 122) connecting the first arm (121; 121) to the spring blade (11; 11), the second arm (122; 122) being connected to the spring blade (11; 11) in a first joining zone (122a; 122a), the hairspring (1; 1) being configured or arranged so that a first displacement of a first amplitude of the first fastening element (13a; 13a) relative to the second fastening element (13b; 13b) does not cause any displacement of the second arm (122; 122), particularly of the first joining zone (122a; 122a), or causes a second displacement of a second amplitude of the second arm (122; 122), particularly of the first joining zone (122a; 122a), relative to the second fastening element (13b; 13b), the second amplitude being less than 0.15 times or 0.1 times or 0.05 times the first amplitude.

The mechanism (20) for adjusting the endshake of a timepiece mobile unit (40) for a timepiece (300) includes: an axis (D), a first component (1), a second component (2) intended to receive or to form at least one bearing (15), interface elements (4) collaborating with the first and second components, a return element (8) returning the first and second components into collaboration with the interface elements (4), and at least first shaped portions (6, 5, 3.1) of the first and second components collaborating with the interface elements (4) to move the interface elements (4) relative to the axis (D) in a plane (P) perpendicular or near-perpendicular to the axis (D) and thus move the second component (2) translationally along the axis (D) relative to the first component (1) under the effect of a rotational movement about the axis (D) of the first component (1) or of the second component (2).
