The timepiece has a chronograph mechanism (4) that can be started, stopped and reset to zero, and a ringing mechanism (6) which emits an acoustic signal when the mechanism (4) is started. The mechanism (4) has a column wheel (10) associated with a control unit that has teeth of number equal to or two times greater than number of columns of the wheel and activates the mechanism (6) when the mechanism (4) is started. |
