Abstract
Disclosed is an analogue chronograph comprising a digital display. The digital display contains an hour and/or minute indicator using numbers. The latter are arranged on individual circular tracks and under a viewing window, form the hour and/or minute indicator in a digital manner. The minute indicator, in particular, can be sub-divided into decimal and unit positions. The chronograph enables the elapsed time to be easily read, even when subjected to strong vibrations, or when the wearer of the chronograph can only glance at the face. The hour indicator has, in addition to numbers 0 to e.g. 9, a symbol similar to a flag, in order to indicate that the limit of the validity range of the time measurement has been reached.
