Such a design therefore makes it possible to minimize the consumption of electrical energy supplied by the electrical energy source 501 used to power the actuation device 500, but also a possible comparison device 400 which will be described below.
  • the actuator 502 actuates the pair of clamps 301, 302 exclusively when the pair of clamps 301, 302 is in position Pos1 ( Figure 6a ), as described below.
  • the beak 306 is located between two teeth arranged in the center of the toothed structure 305.
  • the actuator 502 operates in a first direction illustrated by a solid arrow S1 of the Figure 7

  • the electrical energy source 501 does not deliver any electrical voltage, so that the actuator 502 does not actuate the pair of clamps 301, 302.
  • the pair of clamps 301, 302 remains held in position Pos1 ( Figure 6a ).
  • x is a real number, a a negative real number, and b a positive real number.
  • the electrical energy source 501 delivers an electrical current with a voltage of a first sign, so that the actuator 501 actuates in a first direction so as to move the pair of clamps 301, 302 into the position Pos2, which allows the movement to correct a delay displayed by the display element 71.
  • the electrical energy source 501 delivers an electrical current with a voltage of a second sign, opposite to the first sign, so that the actuator 501 actuates in a second direction, opposite to the first direction, so as to move the pair of clamps 301, 302 into the position Pos3, which allows the movement to correct an advance displayed by the display element 71.
  • the comparison device 400 is arranged so as to compare a rotation period P of the mobile 821 of the finishing gear 82 and a reference rotation period Pref of said mobile 821.

  • the gear ratio here is 1, so that this wheel set 401 also has a rotation period P equal to that of the wheel set 821 (equal to or of the order of 60 seconds knowing that the mobile 821 is here a seconds mobile).
  • the mobile 401 comprises a wheel 402 provided with a tenon 403 intended to cooperate periodically with a lever 404 so as to drive it in rotation against a spring element 405 returning the lever to a predefined position when the tenon is not in contact with the lever.

  • the loss of contact between the arm 404b and the pin 406 makes it possible to determine, at regular or substantially regular intervals (here every minute), the rotation period P. This information is then transmitted to an integrated circuit 407 of the comparison device 400, which is likely to be taken into consideration under the effect of the servo-control device 600.
  • the servo device 600 makes it possible to reposition, in particular periodically, the pair of clamps 301, 302 in position Pos1.
  • the servo device 600 shown in the figures 10 And 11 comprises a lever 602 actuated by the finishing gear train 82 of the 2000 movement, as well as a tenon 601 fixed to the toothed structure 305 of the monolithic structure 900.
  • This lever 602 is designed to act periodically on the tenon 601 so as to retract the selection beak 306 of the toothed structure 305 which is mounted on the structure 900 by means of a flexible structure.
  • the rocker 602 is designed to act punctually on the tenon 601 in a direction perpendicular to the direction of movement of the actuator 502, and in a direction S3, which makes it possible to move the toothed structure 305 away from the beak 306 and thus punctually disengage the beak 306 from the teeth 305.
  • the beak then returns to position under the effect of the restitution of the flexible structures respectively connecting the beak 306 to the frame 304 and the toothed structure 305 to the rest of the structure 900. Due to the specific arrangement and conformation of the different elastic structures, the pair of clamps 301, 302 returns to position Pos1.
  • the lever 602 is designed to be returned by a spring 603 and to be actuated by a cam 604 mounted on a wheel 605 itself mounted in derivation from the finishing gear train 82, for example from a center wheel 822 to which an hour hand 72 of the display device 700 is linked.
  • the servo-control device 600 thus has the advantage of allowing the pair of clamps 301, 302 to be put back into position Pos1, and this periodically (in the embodiment described), without intervention from the actuating device and/or the wearer of the watch. Furthermore, the servo-control device also has the advantage of allowing a unitary action of displacement of the actuator 502 of a given amplitude, and this whatever the direction of actuation (S1, S2). Such a construction therefore makes it possible to minimize the consumption of electrical energy supplied by a primary source, because the action of the actuator is punctual and of a predefined amplitude. Such a construction is notably simpler to implement and more reliable than a construction in which the actuator 502 would be required to carry out all possible transitions between the three stable positions.
  • the mobile 821 is regulated exclusively by the first oscillator 100, with an elastic return system 10 maintained or returned to position Pos1 under the effect of the device 600 so that the first oscillator 100 has a nominal frequency f1.
  • the mobile 821 can be regulated by the first oscillator 100, independently in particular of the devices 200, 400.
  • the servo device 600 has the advantage of being integrated within the mechanical or automatic movement 2000, in particular with regard to the elements 601, 602, 603, 604, 605.
  • the actuating device 500 acting on the frequency selection device 300 can be controlled by the servo device 600.
  • the regulating system 1000 also advantageously comprises an initialization device 800 of the counting device 200.
  • the latter can advantageously be activated by an adjustment mechanism 91 of the display device 700 of the timepiece 3000, for example an adjustment mechanism integrated within the movement 2000.
  • the counting device 200 is initialized in order to take into account the new effective position of the display device 700.
  • the actuating device 500 can be inhibited over a given period following the action of the initialization device 800.
  • the monolithic structure 900 is made of monocrystalline silicon. This advantageously makes it possible to group within it a large number of elements taking part in the regulating system 1000, in particular the devices 300, 500, 600.
  • the structure 900 may be designed to be attached to the frame 6 of the mechanical or automatic movement 2000.
  • the other elements of the regulating system 1000 may also be an integral part of the movement 2000.
  • these other elements, in particular the electronic components, may be arranged on the periphery of the movement 2000, within the timepiece 3000.
  • the comparison device 400 acts every minute or substantially every minute.
  • a value VD can be established at this same frequency.
  • the value VD established just before or just after the contact between the rocker 602 and the tenon 606 (which takes place every hour or substantially every hour) is taken into consideration by the actuating device 500.
  • the value VD can also be established at any other frequency.
  • the movement 2000 can be regulated exclusively by the first oscillator 100 (it is then a mechanical or automatic movement) or by the entire regulating system 1000.
  • the gear chain 82 in particular the mobile 821, is at least partially regulated by the first oscillator 100.
  • the inertial element 4 of the first oscillator 100 is an assembled balance comprising a balance 41 provided with screws or weights 43a which can be moved in order to allow fine adjustment of the rate of the movement 2000, of the order of a few seconds per day as illustrated in the Figure 3 .
  • These screws or weights are for example fixed in a movable manner relative to a serge 410 of the balance 41.
  • These screws or weights can for example be manipulated by a watchmaker when the balance is stopped, by means of a key or a screwdriver which allows them to be moved (by bringing them closer to or moving them away from the axis A4).
  • These tools are generally equipped with means which allow the advance or recoil of the screw or weight to be indicated in order to allow a particularly fine adjustment of the rate of the movement.
  • the rim 410 of the balance 41 advantageously comprises two pairs of weights 43a, 43b and 44a, 44b having distinct conformations, in particular different masses.
  • the weights 43a, 43b are longer than the weights 44a, 44b.
  • the weights 44a, 44b induce a finer adjustment of the than the weights 43a, 43b.
  • the weights are moved in pairs in order to best maintain the balance of the assembled balance wheel 4.
  • these weights allow adjustment of the rate of the 2000 movement over a range of ⁇ 2s/day.
  • the actuation devices 500 and servo-control devices 600 act every hour or substantially every hour on the stiffness selection device 300. It is possible to provide an action at any other frequency.
  • the devices for comparison, actuation of the selection device, and servocontrol of the selection device act periodically, namely at regular intervals.
  • the comparison device and/or the actuation device and/or the servocontrol device are activated at a particular time, not necessarily periodic, for example when a control unit deems it appropriate in the event of a deviation in rate considered too significant.
  • the wearer of the watch can himself activate the actuation device if he notices that the display device of the timepiece is moving ahead or behind.
  • the actuation device can be a purely mechanical device, for example controlled by the wearer of the watch by means of pushers or correctors.
  • the servo-control device can impose a nominal oscillation frequency on the first mechanical oscillator after the control unit or the wearer of the watch has intervened, this servo-control device being controlled by the gear train (at least partially) regulated by the first oscillator.
  • the actuating device can be activated on demand, by a control unit or by the wearer himself.
  • the activation of the servo-control device namely the connection between the finishing gear train and the tenon 601 fixed to the toothed structure 305 of the monolithic structure 900, for example by means of the contacting of the lever 602 with the cam 604 under the effect of an additional clutch system.
  • the lever 602 would then be disconnected from the cam 604 when the actuating device is not actuated, for example during the conventional operation of the movement 2000.
  • the comparison device 400 rests on a wheel set 401 having a rotation period P equal to that of the wheel set 821 of the chain 82 of the movement 2000 (equal to or of the order of 60 seconds, knowing that the wheel set 821 is in particular a seconds wheel set).
  • the display element or the seconds hand 71 of the display device 700 is not essential for the proper functioning of the regulating system.
  • the comparison device 400 could rest on the display element or the seconds hand 71 of the display device 700.
  • the comparison device could comprise means (optical, for example) making it possible to identify the actual position of the display element or second hand 71 at a given time.
  • the modification of the frequency of the first mechanical oscillator involves a modification of the stiffness of the elastic return system, in particular by a modification of the active length of the third elastic return element. It is nevertheless possible to envisage other means of modifying the frequency of the first oscillator.
  • it is possible to modify the environment of the first mechanical oscillator so as to vary the aerodynamic friction to which the oscillating mass of the inertial element is subjected (as taught in the patent CH109521 ).
  • a fairing could for example be provided to surround the oscillating mass of the inertial element and the conformation of the fairing (its geometry and/or its arrangement on the movement frame) could be modified under the effect of the servo-control and/or actuation devices.
  • the electromagnetic environment of the first mechanical oscillator can also be modified under the effect of the servo-control and/or actuation devices, so as to vary its oscillation frequency.
  • the mass elements could, for example, be made of piezoelectric material or magnetostrictive material (as taught within the application EP3120199 ).
  • servo device modifies the frequency of the first oscillator according to a first technique and the actuator device modifies the frequency of the first oscillator according to a second technique.
  • the regulating system implements the first step of operation according to the main mode in which the first mechanical oscillator 100 oscillates at the first predetermined frequency f1.
  • the servo-control, comparison and actuation devices preferably act periodically, namely at regular intervals. In other words, these steps are repeated more particularly at regular intervals.
  • the second step E2 is repeated periodically every minute or substantially every minute (first period P1), while the first and third steps E1, E3 are repeated periodically every hour or substantially every hour (second period P2).
  • the second actuation step may only be implemented when the value VD is not included in the predefined tolerance range [a; b] as mentioned previously.
  • the comparison step is advantageously implemented by the comparison device 400.
  • the comparison step can be implemented at a regular time interval and/or at an interval defined by a watch movement 2000, for example every minute or every hour.
  • the comparison step can be implemented at the request of a user or wearer of the timepiece.
  • the user can act on an organ of the timepiece, such as a push button which activates the comparison device and/or the actuating device.
  • the fourth step occurs at a regular time interval and/or at an interval defined by a 2000 clockwork movement, for example every hour.
  • the second step may comprise or consist of a step of moving the pair of immobilizing clamps along the flexible blade.
  • the solutions described are remarkable in that they comprise a servo-control device which makes it possible to impose a predetermined oscillation frequency f1 on the mechanical oscillator thanks to which the timepiece intrinsically has excellent precision.
  • this servo-control device is controlled by a gear train, in particular a finishing gear train which drives the display device of the watch, which is at least partially regulated by said mechanical oscillator.
  • this servo-control device could also be controlled by other means or devices, in particular in the case of a movement within which the rate correction is effective upstream of the fourth step occurring at regular time intervals and/or at defined intervals.
  • this servo-control device can be at least controlled by a gear train, in particular a finishing gear train.
  • this servo-control device makes it possible to impose a pivot frequency f1 on the mechanical oscillator, called “nominal”, which allows adequate operation of the mechanical oscillator, and this independently of the other devices 300, 400, 500, 600. Furthermore, according to the embodiment described, this servo-control device also has the advantage of allowing the selection of at least one other oscillation frequency (f2, f3) of the mechanical oscillator, by instructing the actuating device allowing the selection of at least one other oscillation frequency.
  • the regulating system comprises a first mechanical oscillator whose “nominal” frequency can be modified, possibly at regular intervals, but which can be restored, possibly at regular intervals, under the effect of a servo-control device controlled by a gear train, in particular a finishing gear train, which is at least partially regulated by said first mechanical oscillator.
  • “nominal” frequency (f1) we mean a frequency of the first mechanical oscillator determined during the design and/or during the assembly of said first oscillator in order to achieve a target chronometric precision when the gear train, in particular the finishing gear train, is regulated exclusively by said first oscillator.
  • This assembly of the first oscillator may for example require a targeted adjustment of the stiffness, in particular of the active length, of a return element of the elastic return system taking part in the first oscillator, or by a targeted adjustment of weights arranged on an inertial element taking part in the first oscillator.
  • the frequency f1 of the system is a frequency such that that the watch movement and/or the timepiece can be certified, in particular can obtain a chronometer certification by the COSC, or even such that the timepiece can obtain the “superlative chronometer” certification from the applicant.
  • the regulating system comprises a first mechanical oscillator whose frequency f1 can be modified (by the actuating device of the selection device) but is then restored (by the servo-control device of the selection device), in particular restored autonomously by an element directly actuated by the finishing gear.
  • the servo-control device makes it possible to impose a predetermined oscillation frequency on the mechanical oscillator, this device being controlled by a gear train, in particular the finishing gear train linked to a display device of the watch, which is at least partially regulated by said mechanical oscillator, and not by a third-party device or by the wearer of the watch.
