ABSTRACT:
A timepiece has a counting mechanism for counting the oscillations of the oscillating regulating member. The counting mechanism includes a plastic block with a retaining pawl and a driving pawl embedded within it. The block has a notch whose two walls serve to limit the movement of a first portion of the driving pawl which is embedded by one extremity in the block and passes through the notch to an elbow formed in the driving pawl which cooperates with the oscillating member to drive a ratchet wheel by a second driving portion of the driving pawl. The retaining pawl has one extremity embedded in an elastic portion of the block and the other cooperates with the ratchet. The block has an eccentric member abutting the elastic portion to adjust the position of the retaining pawl.
