Abstract: A timepiece resilient hand with drive pipes at the ends thereof, including a display index which is at a variable distance from the pipes, and including flexible segments between each pipe and the index each with a web having a substantially constant section, at least one flexible segment thereof includes discontinuous elements projecting from the web thereof in a plane perpendicular to the axis of the pipes and defining, along this web, an alternation of sections, the stiffnesses thereof per unit of length are different from one another, and/or at least one web includes a succession of areas of opposite concavities, projecting on a plane perpendicular to the axis of the pipes

Abstract: The invention relates to a pivot arbor (1) for a timepiece movement comprising at least one pivot (3) made of a first non-magnetic metal material (4) at one of the ends thereof in order to limit the sensitivity thereof to magnetic fields. At least the outer surface of said pivot (3) is coated with a layer (5) of a second material selected from the group comprising Ni and NiP, and preferably chemical NiP. The invention concerns the field of timepiece movements.

At least the first layer (5) of second material is at least partially coated with a second layer (6) of a third material selected from the group comprising gold, silver, copper, platinum, rhodium, palladium and their alloys. The invention concerns the field of timepiece movements.

Abstract: Pallet lever (2) for the escapement mechanism of a watch movement including a fork portion (4), a pallet-stone holder portion (7), pallet-stones (6) mounted on the pallet-stone holder portion, and a lever (8) interconnecting the pallet-stone holder portion to the fork portion. The fork portion includes a fork (12), guard pin (14) and a stud (16), the lever and the pallet-stone holder portion are integral and form a one-piece main body (3) of the pallet lever, and the fork is an added part secured to the main body by means of the stud driven into a securing hole (18) in the main body and a securing hole (20) in the fork. The stud is manufactured from a hard material, particularly a sapphire.

Abstract: The invention relates to a method of fabricating a single-piece micromechanical component including at least two distinct functional levels. According to the invention, the method includes a LIGA process on a single level combined with the machining of the LIGA deposition directly on the substrate.

Abstract: The balance comprising a felloe (3), arms (4) connecting the felloe (3) to the balance staff and inertia blocks (11) is characterized in that the felloe (3) includes studs (7) in its inner surface, a threaded hole (9) into which said inertia blocks (11) are screwed from the inside, without passing beyond the external surface of the felloe (3), passing through said felloe (3) and said studs (7).
