Abstract:
A timepiece movement comprising a coupling mechanism including first and second coupling wheel sets, whereby the rotation of the first coupling wheel set causes the second coupling wheel set to rotate, whereby the coupling mechanism is a centrifugal coupling mechanism including an inertial click secured to the hub of the first coupling wheel set, and meshing with stop members secured to the second coupling wheel set.
