  • the mechanism according to the invention makes it possible to stop the tourbillon or carousel cage during the time-setting operation.
  • the device 100 comprises a control rod 30, which is arranged to cooperate with a control member external to the tourbillon 300 or carousel, to push, substantially radially with respect to the cage axis D, an elastic blade 4 which is arranged to bear substantially tangentially on the cage wheel 5, to stop the cage 10 when the control member passes from a rest position to an active position, and to stay away from the cage wheel 5 when the control member is in its rest position.
  • the device 100 comprises time-setting means 500 which constitute or which control the control member, which is arranged to move the control rod 30 in a first direction of activation when the means of setting the time 500 from a rest position T1 to an activated position T2, and to move the control rod 30 in a second direction contrary to the first direction when the time setting means 500 pass from the position activated T2 to rest position T1.
  • time-setting means 500 which constitute or which control the control member, which is arranged to move the control rod 30 in a first direction of activation when the means of setting the time 500 from a rest position T1 to an activated position T2, and to move the control rod 30 in a second direction contrary to the first direction when the time setting means 500 pass from the position activated T2 to rest position T1.
  • the leaf spring has a smooth bearing surface, in cylindrical portion, of the same radius as the outer diameter of the cage wheel 5.
  • the elastic blade 4 comprises a toothing 41 arranged to cooperate in mesh with the toothing of the cage wheel 5.
  • the elastic blade 4 extends cantilevered with respect to its attachment to the control rod 30.
  • the elastic blade 4 has a convex surface on the side of the cage 10.
  • the elastic blade 4 has a concave surface on the side of the cage 10.
  • oscillator 200 is a balance-spring assembly.
  • the invention also relates to a watch 1000 comprising a timepiece movement 800 comprising energy storage means 400, an oscillator 200, time-setting means 500, and such a limiting device 100.
  • the tourbillon 300 or carousel constitutes a display member of the watch 1000 or is arranged to drive at least one display member of the watch 1000, and the time-setting means 500 constitute or control the control organ.
  • the system is designed to stop the tourbillon, or respectively the carousel, while setting the time.
  • the system rests on the cage wheel with a leaf spring which applies sufficient pressure to stop the cage.
  • This integrated stop wheel mechanism is compact, its manufacture is based on usual technologies, and its cost is therefore moderate.
