  • the roadway or the minute wheel of the watch 200 is driven by the combination, on the one hand, of a star fixed to the roadway or the minute wheel, and of a rocker or a driver or of a rake, the movement of which is controlled by the pendulum 100.
  • the pendulum 100 controls the stop mechanism 20 to stop the resonator 10, brings the displays 4, 5 into the reference position, and positions the clutch mechanism 906 in the open position by relative to the going train 910 which is then independent of the train train of the watch 200.
  • the clock 100 transmits via its interface a defined number of movements necessary to reach the current time, by an integer number of predetermined steps.
  • the clock 100 transmits via its interface a defined number of movements necessary to reach the current time, by an integer number of predetermined steps, plus one or two movements corresponding to one or two predetermined steps additional to allow the waiting time until the top second allowing the stop mechanism 20 to release the resonator 10 of the watch 200.
  • a watch 200 is used whose rocker 931 is arranged to drive a star wheel with thirty teeth by one pitch, or a pinion with fifteen teeth by half a pitch.
  • a watch 200 is used whose rocker 931 is arranged to drive a pinion of fifteen teeth by half a step, and, drives the pinion of fifteen teeth over 80% of the race, and returns to its position of rest, the jumper 904 providing the remaining 20% of the current stroke, and positions the fifteen-tooth pinion for a next half-step.
  • a watch 200 which includes a mechanism for setting the time in constant steps, and includes a corrector 932 coinciding with the interface of the clock 100 or another element making it possible to transmit a va- back and forth, a rocker 931 capable of driving the road by one tooth back and forth, a jumper 904 arranged to maintain the position of the minute display in the interval of the drive functions, a star carried by the minute display with a number of teeth according to the value of the step required, a clutch mechanism 906 between the display train 905, 907, 908, and the finishing train 910 and which is in the open position to setting the time and can be closed in operation of the watch 200, the interface of the clock 100 being arranged to cooperate with the corrector 932 of the watch 200 which drives the rocker 931 which is arranged to drive the star of one step, or half a step.
  • the seventh variant and the eighth variant implement a function controller, to ensure the execution of the functions in the different phases:
  • the function controller has three positions:
  • the controller has two positions:
  • the invention proposes, without limitation, different embodiments, with either a specific controller integrated into the watch, similar to those used in chronographs, or else a controller external to the watch, integrated into the clock.
  • a controller integrated into the watch you can use: - a rotary controller, of the column wheel type, controlled by the interface (with two to five successive stable positions: 1 -2-3-1 -2-3-1 etc.);
  • the watch When the controller is in the clock, the watch only has a reciprocating cam controlled by the interface and returning to rest by default (a stable rest position, and one to three controlled positions: 1-2- 3-2-1-2-3 etc.).
  • This execution can be applied to the eighth variant with a two-position column wheel.
  • the second execution with a simple shuttle is sufficient for the eighth variant where two positions are sufficient, and can replace the column wheel.
  • the execution in which the controller is in the clock is well suited to the seventh variant: the three-position column wheel, described above, is functionally replaced by a three-level spiral, which is located in the clock.
  • This snail controls via a friendly interface a reciprocating cam in the watch. This cam controls the clutch, the stop lever, and the hammer or hammers, as needed.
  • - position 0 initial and final: clutch active, stop lever inactive, and cocked hammer
  • - position 1 return to the reference position, in particular 12 o'clock: clutch inactive, stop lever active, and hammer released;
  • This execution with a controller external to the watch is interesting, because it prevents the watch from remaining in position 1 or in position 2, when the watch is unexpectedly removed from the clock (during the execution of the function).
  • the construction is adapted to prevent the hammer from falling when passing to position 1 when returning to position 0.
  • This execution in which the controller is in the pendulum can be applied to the eighth variant, with a snail and a two-position cam.
  • such a controller responds to the desired time-setting functions, allows the disengagement of the display of the going train, and their engagement, allows the hammer to be controlled if necessary, and allows the stop lever to be controlled.
  • the sympathetic 1000 set includes an option with a clutch mechanism, in order to be able to deactivate the function for storing the watch stopped on the clock.
  • the first interface comprises a first external actuator in the clock, and a first internal actuator in the watch.
  • the second interface comprises a second external actuator in the clock, and a second internal actuator in the watch.
  • the third interface comprises a third external actuator in the clock, and a third internal actuator in the watch.
  • the nth interface has an nth external actuator in the clock, and an nth internal actuator in the watch.
  • the striking mechanisms have the advantage of providing precise references for the time settings, which one can imagine using for setting the time of sympathetic watches.
  • the striking snails can be used for the time-setting mechanism, in an example of a time-setting carried out in five-minute steps, the corresponding snail must have 144 five-minute steps, and will not be used for The ring.
  • the hour cochlea is in principle jumping with the surprise mechanism, so a priori even the drive is special.
  • the watch can be chiming, but this makes the system a little more complex as one has to isolate the chimes during sympathetic operation where the sympathetic clock 100 and the sympathetic watch 200 cooperate, as the chimes would ring continuously while on. hour and could cause the mechanism to jam.
