  • the transmission mechanism advantageously comprises a third mobile 71 in kinematic connection with the indicator member 1, in particular a third mobile meshing with a wheel 13 of the first mobile and therefore integral with the indicator member 1.
  • the third mobile 71 is movable relative to the frame 9, in particular movable in rotation relative to the frame 9 around an axis A2 parallel to the axis A1.
  • the third mobile 71 comprises a finger 72 arranged so as to act on the energy accumulator, in particular on the second end 81a of the spring, in particular on the pin 84, to move it from a first notch 221a to a second notch 221b adjacent to plate 22.

  • the hammer comprises an element 31a for returning the first tip 31 to a rest position relative to the body of the hammer, in particular relative to the second tip 41. This rest position of the first tip 31 is shown on the figures 12 And 14 .
  • the slide connection between the first purlin 31 and the hammer body can be made by pins 351 provided on the body 35 and cooperating with a groove 311 made on the first purlin 31.
  • the element 31a for returning the first tip 31 to the rest position comprises an elastic arm 31a, which is integral with the first tip 31 or integral with the first tip 31.
  • the cam 3 can be driven onto the tigeron 12 and angularly indexed relative to the wheel 13.
  • This cam 3 presents, for example, a heart shape as visible on the figures 12 And 13 so that the first failure 31 can put the first mobile and therefore the indicator member back into the first predetermined configuration P1, which can for example be the position occupied by the needle 1 on the figures 1 and 2 .
  • the first predetermined configuration P1 of the first mobile also induces a repositioning of the plate 22 in a stable position such as that represented on the figures 7 And 11 .
  • the return to the first predetermined configuration of the first mobile induces a return to the predetermined position of the third mobile 71 and therefore a return to the predetermined position of the locking disk 720 as shown in the figures 7 And 11 .
  • the locking disk authorizes the rotation of the plate 22 and therefore the rotation of the second mobile.
  • the cam 4 is fixed on the tubular element 23 on which the support 2 is mounted.
  • This cam 4 shown on the figures 12 And 13 can be shaped so that the second tip 41 can put the support 2 back in a predetermined position P2, which can, for example, be the position occupied by the support 2 on the figures 1 And 3 . Since the support 2 is friction mounted on the plate 22, the support 2 and the cam 4 can be disengaged from the plate 22 while it is returned to the predetermined position. This allows resets to predetermined configurations independent of the support and the plate 22.
  • a mode of execution of an operating method of a display system mentioned above or of a watch movement mentioned above or of a timepiece mentioned above is described below with reference to the figures 7 to 11 on which in a For the sake of clarity, support 2, as well as wheels 13 and 73 are not shown.

  • the indicator member is arranged in position facing the window 10a, as shown on the figures 1 and 2 .
  • the indicator member can be held in this position by means of the jumper 6.
  • the plate 22 is, for its part, held in position by means of the spring 81 and the pin 84 which is housed in a first notch 221a of plate 22 and which is pressed against the stop 83a formed on the frame 9.
  • the Figure 7 can, for example, represent the state of the display system 100 before the activation of the chronograph system, and in particular before the activation of the drive mechanism of the first mobile.
  • the support 2 is advantageously arranged so that the graphic element “0” appears in the window 10a.
  • a second step represented on the figure 8 the display system displays time information or derived from the time by cooperation of the indication member and the limb.
  • This step is for example obtained after switching on the chronograph system.
  • FIG 8 represents the display system 100 once the drive mechanism of the first mobile has been engaged. The rotation of the wheel 13 and therefore of the first mobile 11 induces the movement of the indicator member 1, and consequently of the wheel 73 and the finger 72.
  • the indicator member 1 has covered a little more than half of the range of the limb, and the driving finger 72 has just come into contact with the pin 84 of the spring 81.
  • the display system arms the energy accumulator 8 or stores energy in the energy accumulator 8.
  • This action is for example carried out by the action of the finger 72 moving the second end 81a of the spring.
  • the pin 84 is, for example, guided by the side connecting the first notch 221a to the second notch 221b adjacent to the plate 22 and by the cam path 83 formed on the frame 9.
  • the second end 81a of the spring is no longer in contact with the stop 83a and the spring tends to rotate the second mobile 21, in particular the plate 22, in the counterclockwise direction around the axis A1.
  • the rotation of the plate 22 is blocked by means of the locking disk 720 cooperating with the periphery 220 of the plate.
  • the support 2 is thus maintained in the initial angular position by this means.
  • the spring is thus armed until the pin 84 of the spring 81 is housed in the second notch 221b of the plate 22, as shown in the Figure 10 .
  • the plate 22 remains locked in the angular position as explained previously.
  • the indicator member 1 has then covered almost the entire extent of the limbus.
  • the display system unlocks the position of the support 2.
  • the third mobile 71 arrives in a configuration in which the locking disk unlocks and therefore authorizes the rotation of the plate 22.
  • the pin 84 is thus free to drive the plate 22 via its notch 221b under the effect of the restitution of the spring 81.
  • the support 2 is moved thanks to mechanical energy released by the energy accumulator.
  • the plate 22 is rotated by a quarter of counterclockwise until you reach the configuration of the Figure 11 , or in a configuration similar to that shown on the Figure 7 .
  • the rotation of the plate is instantaneous.
  • FIG 11 illustrates the display system 100 just after the restitution of the spring 81.
  • the pin 84 is again pressed against the stop 83a, and holds the plate 22 in position by means of the notch 221b.
  • the support 2 is advantageously arranged so that the graphic element “30” appears in the window 10a.
  • the support 2 is thus capable of performing instantaneous jumps of 90°. Such jumps therefore allow the display system 100 to move from the first configuration C1 illustrated on the figure 1 to the second configuration C2 illustrated on the figure 2 Or vice versa.
  • a fifth step the operation of the chronograph system is stopped.
  • the display system then indicates the time measured and recorded. This stop can be controlled by an action of the wearer of the timepiece on a control member.
  • the display system is reset or reset to zero.
  • This sixth step comprises for example a first phase in which the wearer of the timepiece exerts an action on the display system, in particular elementary action of the user on the display system, in particular on the control member , for example pressing the user on the OC pusher of the display system.
  • the action can be elementary in the sense that only an elementary movement is necessary to trigger the reset or reset. For example, only the pressing movement on the pusher is necessary, the return movement not being necessary to control the reset or reset.
  • the timed time displayed by cooperation of the indicator member and the limb is returned to a predetermined configuration, in particular is reset to zero.
  • the indicator member 1 is arranged in the first predetermined configuration and/or the graphic element is returned to the second predetermined configuration.
  • the first failure 31 comes into contact with the cam 3 so that the indicator member rotates around the axis A1 until reaching the first predetermined configuration P1. It follows that the entire first mobile rotates and the third mobile also rotates accordingly until reaching a configuration in which the plate can rotate and be brought into a configuration represented by the figure 7 or the Figure 11 if it wasn't already there. The plate is then in a stable position, the second end of the spring being in contact with the stop 83a.
  • the hammer 34 can continue its stroke so as to allow, in a second sub-phase of actuation of the hammer, the actuation of the cam 4 by means of the second purlin 41 under the effect of the elastic deformation of the arm 31a.
  • the hammer 34 is thus shaped in such a way that it can act on the cam 3 in a first sub-actuation phase, and that it can act on the cam 4 in a second sub-actuation phase.
  • the action of the failure 41 on the cam 4 causes the rotation of the cam 4 around the axis A1 and therefore the rotation of the support around the axis A1. Due to the friction existing between the support and the plate, the support can during this operation rotate without the plate rotating. It is thus possible to put the graphic element, in particular the support, back into the second predetermined configuration P2.
  • FIG. 12 represents the system before returning to predetermined configurations P1, P2.
  • the first and second failures 31, 41 are respectively out of range of cams 3 and 4.

  • the second mobile can comprise a body 22 or plate provided with notches and a member 2 of second mobile 21, in particular a support or disc 2, attached movable with friction, in particular movable by lanterns, on the body around the axis A1.
  • the actuation system may include a device 4, 34 for returning the first mobile to a predetermined configuration, comprising an element 4 for returning the member 2 of the second mobile 21 to a predetermined configuration, in particular a cam 4.
  • the second mobile is put back into a predetermined configuration, in particular the body 22 can be brought into the first predetermined configuration P1 and/or the member 2 can be brought into the second predetermined configuration P2. This is achieved for example by the action of the hammer.
  • the hammer 34 can continue its stroke so as to allow, in a second sub-phase of actuation of the hammer, the actuation of the cam 4 via the second purlin 41 under the effect of the elastic deformation of the arm 31a.
  • the hammer 34 is thus shaped in such a way that it can act on the cam 3 in a first sub-actuation phase, and that it can act on the cam 4 in a second sub-actuation phase.
  • the action of the failure 41 on the cam 4 causes the rotation of the cam 4 around the axis A1 and therefore the rotation of the member 2 around the axis A1. Due to the friction existing between the member 2 and the body 22, the member 2 can during this operation rotate without the body 22 rotating. We can thus put the member 2 back into the second predetermined configuration P2.
  • the systems, devices and methods have been used to implement a chronograph function.
  • the chronograph can be started and stopped on demand through a conventional chronograph mechanism.
  • the systems, devices and methods have been described with circular limbs and indicator bodies making a complete turn of the limb.
  • the systems, devices and methods may relate to non-circular limbs cooperating with retrograde type indicator members.
  • the systems, devices and methods have been described with a plate or second mobile performing instantaneous jumps of 90°. However, depending on the different aspects and/or embodiments, the systems, devices and methods may relate to embodiments where a plate or second mobile performs instantaneous jumps of any other angular value.
  • the systems, devices and methods have been described with three windows associated with a limb. However, depending on the different aspects and/or embodiments, the systems, devices and methods may relate to achievements where another number of windows, in particular 1 or 2 or 4 or 5 or 6 or 10 or 12 windows are associated with a limb. .
  • the systems, devices and methods have been described with three windows associated with a limb and arranged at 120° relative to the axis A1 and a support 2 making jumps of 90° relative to axis A1 and graphic elements arranged every 30° relative to axis A1 on the support.
  • This configuration is interesting because it allows two sets of graphic elements to be placed on support 2.
  • the at least one graphic element is arranged so that, in the different configurations of the at least one graphic element, the at least one graphic element defines or participates in the definition of several intervals complementary to a scale of values of a timed time.
  • the first graphic element and the fourth graphic element can be seen as constituting the same first editable graphic element.
  • the second graphic element and the fifth graphic element can be seen as constituting the same second editable graphic element.
  • the third graphic element and the sixth graphic element can be seen as constituting the same third editable graphic element.
  • the different configurations of the at least one graphic element can define or participate in the definition of more than two complementary intervals, in particular three, four, five or six complementary intervals.
  • the number of complementary intervals is defined by the number of configurations.
  • the amplitudes of the different complementary intervals are equal.
