Moonphase complication: How it works
A moonphase complication is a feature that displays the current phase of the moon on the watch. It changes in real-time throughout the lunar cycle. It is a popular and elegant feature that adds a unique touch to the design of a watch.
Moonphase complication works by utilizing a small disc that is located on the watch dial, usually within a subdial. The disc is decorated with an image of the moon and stars that rotate over a period of 29.5 days, which is the length of a lunar cycle.
This disc is divided into two parts, each representing one-half of the lunar cycle. One half is usually painted blue or black to represent the night sky, while the other half is left blank or painted white to represent the moon. The image of the moon appears to wax and wane as the disk rotates, mimicking the actual phases of the moon.
A gear train linked to the main movement of the watch controls the movement of the disc. The gear train is designed to track the lunar cycle accurately and ensure that the disc rotates at the proper speed.
