A timepiece, able to indicate at least the hours, minutes and seconds, having a rotary stem movable into three axial positions: a stable neutral position in which the timepiece operates normally, a stable outer position and an unstable inner position. When the stem is pulled to the outer position the timepiece switches from the normal operating mode to a correction mode in which it is possible either to correct the minutes indication by rotating the stem slowly, or to perform a change of the hours indication done by rotating it rapidly. Whenever the stem is simply pulled out, or is pulled out followed by a correction of the minutes indication, and is then returned to the neutral position, the timepiece switches automatically and for a set maximum time, e.g. one minute, to a transitory mode in which it is possible to reset the seconds to zero and, at the same time, to cause a return to the normal operating mode by pushing in the stem. If after a set time, no pressure has been exerted, the timepiece resumes automatically normal operation. No transitory mode is provided when only a change of the hours indication is performed. |
