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.
Claims6
A timepiece movement including:
- a coupling mechanism, wherein the coupling mechanism is a centrifugal coupling mechanism that further comprises:
- a first coupling wheel set having a hub;
- a second coupling wheel set disposed so that rotation of the first coupling wheel set drives the second coupling wheel set in rotation;
- an inertial click secured to the hub of the first coupling wheel set;
- and
- stop members secured to the second coupling wheel set, wherein the inertial click is operably disposed to press against the stop members when the first wheel set rotates.
