Abstract: A watch is formed by a mechanical movement incorporating a mechanical resonator. The watch comprises a display displaying the time and a correction device for correcting the displayed time, which is formed by a receiver for receiving an external correction signal which is supplied by an external electronic device (in particular a mobile phone), a braking device for braking the mechanical resonator and an electronic controller. The correction device is arranged such that it can correct the time displayed as a function of a time error (loss or gain) contained in the external correction signal. 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 at least for the most part the time error in the time displayed.

Abstract: The present invention concerns a piezoelectric element (3) for an automatic frequency control circuit. The element includes a balance spring (7) formed of a strip of piezoelectric material, a first electrode connected to the automatic control circuit, and disposed on all or part of one side of the strip, and a second electrode connected to the automatic control circuit and disposed on all or part of another side of the strip of piezoelectric material. The element further comprises at least two discontinuous layers of an insulating material, each discontinuous layer of insulating material being disposed on at least one side of the strip of piezoelectric material and separating a first electrode from a second electrode. The discontinuous layers of insulating material are distributed on predetermined portions of the balance spring substantially forming arcs, with a predetermined angular periodicity.

Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A mechanical oscillator, formed of a mechanical resonator and a device for maintaining oscillation, and an auxiliary oscillator forming a reference time base including a synchronisation device arranged to slave the medium frequency of the mechanical oscillator on that of the auxiliary oscillator. The synchronisation device includes an electromagnetic braking device which is formed of a coil and at least one permanent magnet and arranged such that an induced voltage is generated between the terminals of the coil in each alternation of the oscillation of the mechanical resonator. The synchronisation device is arranged to be able to reduce momentarily the impedance between the terminals of the coil during distinct time intervals, any two successive time intervals exhibiting between the respective starts thereof a time distance substantially equal to a positive whole number multiplied by half of a set-point period for the mechanical oscillator.

Abstract: 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.
