摘要： A timepiece with a mechanical movement which includes an indicator mechanism of at least one time data item, a mechanical resonator forming a mechanical oscillator which paces the running of the indicator mechanism, and a regulation device to prevent a potential time drift in the running of the indicator mechanism. The regulation device is formed by a master oscillator and a mechanical braking device of the mechanical resonator, this mechanical braking device being arranged to be able to apply periodically to the mechanical resonator braking pulses at a braking frequency determined by the master oscillator. The system, formed of the mechanical resonator and the mechanical braking device, is configured so as to enable the mechanical braking device to be able to start the braking pulses at any position of the mechanical resonator. The braking pulses have a duration less than one quarter of a set-point period.

摘要： A recharging device for an electronic or electromechanical watch equipped, on the one hand, with a device for the storage of electrical energy for powering electronic components of the watch and, on the other hand, with an auxiliary source of electrical energy adapted to power the device for the storage of electrical energy for recharging thereof. The device includes a casket provided with a support for receiving the watch. The device further includes at least one source of energy configured to supply energy to the auxiliary source of electrical energy, when the watch is placed on the receiving support, so that the auxiliary source of electrical energy converts the received energy into electrical energy and delivers a charge for maintaining a predetermined level of power supply voltage to the device for the storage of electrical energy.

摘要： A timepiece includes a mechanical oscillator, formed of a mechanical resonator, and a device for regulating the frequency of the mechanical oscillator. This regulation device includes an auxiliary oscillator, an electromechanical device for stopping the mechanical resonator, a sensor arranged to detect the passage of the mechanical resonator via the neutral position thereof, and a measuring device arranged to measure a time drift of the mechanical oscillator. The regulation device is arranged to stop, during a given alternation, the natural oscillation movement of the mechanical resonator selectively either momentarily during a first half-alternation occurring before the passage of the mechanical resonator via the neutral position thereof when the time drift measured corresponds to at least a certain gain, or prematurely during a second half-alternation occurring after the passage of the mechanical resonator via the neutral position thereof when the time drift measured corresponds to at least a certain loss.

摘要： A watch formed by a mechanical movement incorporating a mechanical resonator, including a display displaying the actual time, a correction device formed by a device for detecting the passage of at least one hand through at least one reference time position and by an electronic correction circuit allowing an overall time error for the display to be determined, and a device for braking the mechanical resonator. The correction device is arranged such that it can correct the actual time displayed as a function of the overall time error (loss or gain) previously determined. For this purpose, the correction device is arranged such that the braking device can act on the mechanical resonator during a correction period to vary the running of the drive mechanism of the display, in order to correct the actual time displayed.

摘要： A timepiece includes a mechanical movement with a mechanical oscillator and an electronic device for regulating the medium frequency of this mechanical oscillator. It includes an electromagnetic transducer and an electric converter which includes a primary storage unit for powering the regulation circuit. The electromagnetic transducer is arranged to supply a voltage signal exhibiting first voltage lobes in first half-alternations and second voltage lobes in second half-alternations of the oscillations of the mechanical oscillator. The regulating device includes a load pump arranged to transfer electric loads from the primary storage unit into a secondary storage unit, these electric loads being extracted selectively in different time zones according to a time drift detected in the functioning of the mechanical oscillator relative to an auxiliary oscillator, particularly quartz-based.

摘要： A timepiece includes a mechanical oscillator, formed by a balance and a piezoelectric balance spring, and a regulating device for regulating the frequency of the mechanical oscillator which is arranged to be able to produce time-separated regulating pulses, each consisting of a momentary decrease in an electrical resistance applied by the regulating device between two electrodes of the balance spring relative to a nominal electrical resistance. Each regulating pulse produces a variation of rate which varies as a function of its moment of starting in a half-period of the mechanical oscillator, the characteristic function of this variation of rate relative to the moment of starting of at least one regulating pulse respectively in at least one half-period of the mechanical oscillator being negative in a first temporal zone of at least one half-period and positive in a second temporal zone of at least one half-period.

摘要： A timepiece is provided with a mechanical movement which includes a mechanical resonator, a sensor detecting oscillations of the mechanical resonator, and a braking device arranged to generate braking pulses in response to a control signal provided by a control circuit associated with an auxiliary oscillator. The control circuit is arranged to be capable of detecting a negative or positive temporal drift in the oscillation of the mechanical resonator and to generate, in a correction period, in association with the braking device, when the temporal drift corresponds to at least a certain loss, a series of braking pulses which are applied to the mechanical resonator at a frequency FSUP in a given range of values which is preferably higher than a frequency FZ (N)=2·F0c/N, F0c being a set point frequency for the mechanical resonator and N a positive integer number.

摘要： A process for producing a metal alloy balance wheel by molding includes a) making a mold in the negative shape of the balance wheel; b) obtaining a metal alloy that has a thermal expansion coefficient of less than 25 ppm/° C. and is able to be in an at least partly amorphous state when it is heated to a temperature between its glass transition temperature and its crystallization temperature; c) putting the metal alloy into the mold, the metal alloy being heated to a temperature between its glass transition temperature and its crystallization temperature so as to be hot-molded and to form a balance wheel; d) cooling the metal alloy to obtain a balance wheel made of the metal alloy; and e) releasing the balance wheel obtained in step d) from its mold. The process also includes a step for over-molding flexible centering components in the hub.
