Abstract
A chronograph watch comprises time keeping first indicators (H, M, S1) used for displaying the time of day and chronograph second indicators (h, m, S2) used for displaying an interval of time in response to a control arrangement (P1, P2) with the aid of which the chronograph can be started, stopped and reset to zero. The chronograph watch includes instantaneous conversion means for at least one of the second indicators (here the seconds counter S2) into an indicator of another function, for example an indication of the date (Q), when the chronograph is not in use. In such example there is also provided the transformation of the minutes counter (m) into a four-year cycle indicator (BISS) and the hours counter (h) into a months indicator (Mo).
