Chronograph watches can measure and display elapsed time. Usually three subcounters on the dial display the elapsed seconds, minutes and hours.

Watches featuring a GMT complication (which stands for Greenwich Mean Time) can display a second time zone thanks to an additional hand. They are much appreciated by travelers and airline pilots.

The 24H indicator is often associated with watches displaying several time zones.

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.
