The timepiece has on one part several incrementing type counters, each operated by a spring-controlled pushbutton element. The counter devices also have an indicator, a ratchet wheel (11) having a return spring (16), a drive pawl, and a retaining pawl. The ratchet wheels advance by one step in opposition to the action of the return spring and the indicating elements each time the respective push-element is subjected to a pressure (F1). The reset mechanism is controlled by a single pushbutton (20). The mechanism has a device arranged such that, on pressing the reset pushbutton the pawls are rendered inoperable and the counter springs can then simultaneously return to the zero position. The pawls are rendered inoperable by a rotating element (17) in the centre of the timepiece. |
