An adjusting device for an electronic digital display which has a first pulse generator for producing counting pulses is described. The adjusting device includes a 'second' pulse generator which can be adjusted over a range of frequencies and a 'third' pulse generator which operates at a higher frequency. A discriminator determines whether the pulse frequency of the second pulse generator exceeds a predetermined value and if it does the, third pulse generator is switched in. This has the advantage that of the, display of a chronometer has to be adjusted by several hours this can be, done much more quickly.
