Chronograph

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

Split-Seconds Chronograph

Split-seconds chronographs can measure intermediary time thanks to another second hand which is able to catch up with the other running hand if needed.

Power Reserve Indicator

The power reserve indicator tells you the time the watch will continue to function. It can either be seen on hand winding or automatic watches.

Perpetual Calendar

The perpetual calendar complication displays the day, date and month, but it requires less adjustment than an annual calendar. This complication knows the number of days in each month but it also knows the year so that it will automatically adjust for leap year. The next time a perpetual calendar will have to be adjusted is in the year 2100.

Moonphase

Watches featuring a moonphase complication display new moons, first quarters, full moons and last quarters.
