A chronograph mechanism including an energy accumulator, a regulating system, a chronograph counter train including a minute-counter having a minute wheel set and at least one minute indicator member, and a seconds-counter having a seconds wheel set and a seconds indicator member, a chronograph zero-reset mechanism including a minute zero-reset mechanism. The minute zero-reset mechanism is arranged to cooperate with the minute wheel set, the minute indicator member being permanently integral with the minute wheel set, and the chronograph counter train includes an uncoupling device between the minute-counter and the seconds-counter, arranged to kinematically connect the minute wheel set and the seconds wheel set during the counting and to uncouple the seconds wheel set from the minute wheel set when the chronograph mechanism is reset to zero.
