What is a moon-phase complication?

A moon-phase complication is a watch component that displays the evolution of the lunar cycle, from new moon to full moon.

This is done using a lunar printed with two moons, partially visible on the dial. This disc moves forward a little each day to reproduce the actual cycle, which lasts 29 days, 12 hours and 44 minutes.
