Abstract: The invention relates to an escapement device (400) comprising a first escapement wheel (1), a second escapement wheel (2), and a brake-lever (3), said second escapement wheel being disposed between the first escapement wheel and the brake-lever, in particular the second escapement wheel coming into contact and engaging with both the first escapement wheel and the brake-lever.

Abstract: A process for manufacturing a timepiece component, in particular a multi-level timepiece component, comprising a step of manufacturing at least one metal layer (13) of the timepiece component having an upper surface (15), wherein it comprises the following steps: E3: forming at least one cavity (14) in the upper surface (15) of the metal layer (13) of the timepiece component; E5: forming another metal layer (23) at least partially superposed on said upper surface (15) comprising a cavity (14), by a galvanic deposition of a metal or of an alloy, filling at least said cavity (14).

Abstract: A process for adjusting a device including a first piece and at least one second piece, wherein the at least one second piece is fixed to the first piece by a joint made from a first material arranged between the first and second piece. The first material is an at least partially amorphous metal alloy. The process further includes: heating at least the joint to a heating temperature in a range of between a glass transition temperature and a crystallization temperature of the first material; modifying a position of the at least one second piece until a desired determined position is obtained; cooling at least the joint so that it retains its at least partially amorphous state.

Abstract: The invention relates to a timepiece fitted with a lever escapement wherein the end of contact angles ?1 and ?2 between the pallet stones and the escapement wheel are respectively higher than the locking-angles ?2 and ?1 of the two locking positions of the lever. This escapement requires neither adjustment nor final alteration of the position of the pallet stones.

Abstract: The invention relates to a one-piece composite micromechanical timepiece component including a first functional level including an impulse pin made of a first material arranged to cooperate with a member, the first functional level also including an electroformed portion made of a second metallic material partially overlapping the impulse pin and a second functional level including only the electroformed portion forming a roller also arranged to cooperate with the member.

Abstract: An escapement mechanism for a timepiece, includes an escapement wheel (1), an escapement anchor (2) including a body (2a), and a fork (5), the body (2a) including pallets (3, 3?, 4, 4?) that engage with the escapement wheel (1), the body (2a) having a shape that makes it possible to delimit an internal space (11) for arranging the escapement wheel (1), the pallets (3, 3?, 4, 4?) including two rest pallets (3, 3?) and two impulse pallets (4, 4?), protruding in the internal space (11). The mechanism includes a pin (7) of a roller (6) that is secured to a regulating device, characterized in that the roller (6) and the fork (5) are arranged with respect to one another such as to impart an alternating translation movement with respect to the escapement wheel (1) to the anchor (2) when the pin (7) engages with the fork (5).

Abstract: Escapement mechanism (3) for a watch movement including a pallet lever (7) with a fork (13) and a roller device (4) with an impulse-pin coupled to a balance (2). The fork includes an entry horn (19) and an exit horn (21), the impulse-pin including a first cam portion (12a, 12b) configured to engage the entry horn, and a second cam portion (14a, 14b) configured to engage the exit horn. The first cam portion includes a first cam surface (12a) configured to engage the entry horn on a first level (10a, 10b), and the second cam portion includes a second cam surface (14b) configured to engage the exit horn on a second level (10b, 13b), the first and second levels being staggered in a direction parallel to the axis of rotation (A) of the roller device.

Abstract: Pallet lever for an escapement mechanism including a balance with a pin of a given pin radius and oscillating over a given radius of gyration, this pallet lever including two horns for cooperation with a pin of this type. These horns are symmetrical to each other relative to a median plane passing through a pallet lever pivot axis, and each includes a concave inner profile over a first radius of curvature greater than or equal to the sum of this radius of gyration and this pin radius, this concave inner profile being adjacent to a convex outer profile over a second radius of curvature less than or equal to the difference between this radius of gyration and this pin radius.

Abstract: The driving and transmitting element (10, 50) is in the form of a ring (20) having an outer face (32) from which a stud (40) extends radially. Application to a roller table (60, 70) of a lever escapement (80) for a timepiece (90) including such a driving and transmitting element (10, 50) for rotating the anchor (84) and for transmitting an impulse from the anchor (84) to the roller table (60, 70).
