Moon Phase Complication
The moon phase complication is a fascinating feature in timepieces that displays the moon’s current phase through an aperture on the dial, using graphical or radial indicators. There are two main types of moonphase complications: the bosom moon phase and the radial moon phase, with some watches also featuring a date window for added functionality.
Furthermore, waxing is the moon’s progression from a new to a full moon. The date change on a watch with a moonphase complication also occurs during this period. The four primary moon phases are New Moon, the first quarter, the full moon, and the last quarter.
