摘要： The invention relates to a mechanical watch comprising an oscillator (1) embodied with a frame (5) supporting a vibratory mass or masses (2, 3), wherein each vibratory mass (2, 3) connects to at least one flexural member (6-13), the watch further comprising an escape wheel (14), and anchor teeth (15, 16) that are indirectly connected with the vibratory mass or masses (2, 3), which anchor teeth (15, 16) cooperate with the escape wheel (14), wherein motions of the anchor teeth (15, 16) depend on motions of one or more of the flexural members (10, 11, 12, 13) that provide connections between the vibratory masses (2, 3) without said flexural members (10, 11, 12, 13) connecting directly to the frame (5). Said flexural members (10, 11, 12, 13) provide connections between the vibratory masses (2, 3) without connecting directly to the frame (5) are free from rigid sections and support a movable rigid portion (4) of the oscillator (1) that is separate from the flexural members (10, 11, 12, 13), which movable rigid portion (4) is suspended from the movable masses (2, 3) through said flexural members (10, 11, 12, 13) that are free from rigid sections.

摘要： The invention relates to a movement (1) for a watch, which movement comprises a first layer (2) comprising a compliant mechanism, preferably a monolithic compliant mechanism (3), for a function or at least part of a function of the movement, an energy storage (16), and a second layer (15) comprising a gear train (17) for transmitting energy from the energy storage to the compliant mechanism to perform the function or part of the function and/or for transmitting energy from the compliant mechanism to the energy storage. The first layer (2) comprises a further compliant mechanism (20, 30, 40) for a further function or at least part of a further function of the movement.

摘要： The invention relates to a movement for a watch, which movement comprises a rotatable indicator (2-4; 6,7), such as an indicator comprising a chronograph seconds hand (2-4) or minute counter (6,7), the indicator in turn comprising a cam (2; 6) and a brake mechanism (20; 11) movable between at least a first posi-tion wherein the brake mechanism (20; 11) engages the in-dicator (2-4; 6,7) to maintain the indicator in a rota-tional position and a second position wherein the brake mechanism (20; 11) releases the indicator. The movement further comprises a reset mechanism (30) for returning the cam (2; 6) and thus the indicator (2-4; 6,7) to a default position, such as a zero or start position, wherein the cam (2; 6), at least part of the brake mechanism (20), and at least part of the reset mechanism (30) are positioned in the same layer.

摘要： The invention relates to a movement for a watch, which movement comprises an escape wheel (9) having a plurality of teeth (10) and an oscillator (1) having anchor teeth (8), which anchor teeth (8) are controlled by the oscillator (1) to alternately block and release the teeth (10) of the escape wheel (9), wherein at least the escape wheel and the anchor teeth (10, 8) share an imaginary plane (P). At least some of the teeth (10) of the escape wheel (9) and/or at least one of the anchor teeth (8) of the oscillator (1) comprises two surfaces defining a circumferential edge (10B, 8B) that is aligned with the end surfaces (8A, 10A) of the teeth (8, 10) of the other.

摘要： The invention relates to an energy harvester (1) for a wearable and/or portable device, such as a wrist watch (20) or remote control, the harvester comprising a mass (5) that is arranged to move back and forth between extreme positions and that is coupled to an energy converter and/or an energy storage (3, 22) via a transmission (7-12). The transmission ratio between the mass (5) and the con-vertor and/or storage (22) is variable and, for at least one of the extremes positions, increases as the mass (5) moves towards that position.

摘要： The invention relates to a method of manufacturing a plurality of mechanical resonators in a manufacturing wafer, the resonators being intended to equip a regulating member of a timepiece, the method comprising the following steps:
(a) fabricating a plurality of resonators in at least one wafer according to reference specifications;
(b) measuring the actual frequency of each of the plurality of resonators;
(c) determining the offset of the actual frequency of the resonators with respect to the reference specifications;
(d) applying on at least one of the resonators at least two masses from a series of tuning masses to compensate the offset of the concerning resonator to bring the resonator closer to the reference specifications.
