A shock absorbing coupling device for a timepiece, includes a coupling wheel () able to take a coupled position and an uncoupled position, a coupling member () bearing the coupling wheel and a coupling cam () engaging with the coupling member () to define the coupled position and uncoupled position of the coupling wheel (). The device also includes a locking member () rigidly attached to the coupling cam () and an intermediate member () controlled by the coupling member (). The intermediate member () is intended to engage with the coupling member () and the locking member () to prevent or limit the movement of the coupling member () under the effect of a shock when the coupling wheel () is in the coupled position, to thus avoid the coupling wheel () leaving the coupled position.

Device for a timepiece

The escapement comprises an escapement wheel () and an anchor (). In the place of the traditional limiting walls or pins, the escapement comprises, on the anchor () and/or the escapement wheel (), means () for limiting the oscillations of the anchor () during normal operation of the escapement. In order to prevent contact between the impulse beak () of the pallets () and the escapement wheel () upon impacts, the escapement wheel () has protrusions () at its periphery.
