Chronograph watches can measure and display elapsed time. Usually three subcounters on the dial display the elapsed seconds, minutes and hours.
Monopusher chronographs are complicated chronographs. Actually the monopusher has three different functions: start, stop and reset.
Watches featuring dual time system indicate local time in different world cities. They are very appreciated by travelers.
The night and day indicator is an aesthetic complication which displays on the dial the movement of the sun and the moon. This complication must not be confused with the moonphase.
The date is a small window on the dial which indicates the day of the month (between 1 and 31).
