ABSTRACT:
A counting mechanism for a timepiece in which the drive means therefor oscillates a counting wheel, which in turn drives a co-axially mounted ratchet wheel in one direction. The counting wheel and ratchet wheel are interconnected so that during each oscillation of the counting wheel, both wheels first move in unison in one direction and then the counting wheel alone is driven in the other direction against a resilient coupling member while the ratchet wheel is held stationary by a pawl. The counting wheel is released between each cycle of oscillations, so that it can be returned by the resilient coupling member to its normal position with respect to the ratchet wheel.
