Minute repeater watches ring whenever you activate the pusher (contrary to chimes). The most complicated ones can ring hours, quarters and minutes.

Just like the « sonnerie » watches, these watches indicate the hours and quarters by means of hammers hitting bells. Sonnerie Cathedral watches have a lot of different melodies for quarters. The most famous one is Westminster’s.

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.

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

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