In Japan, the moon shines brilliantly against the autumn night sky and moon-viewing is customary, a tradition that originated in China. Jugoya literally means the fifteenth day of the eighth month of the lunar calendar. On that evening, a full moon can be seen.
As homage to the Japanese moon-viewing tradition, Miyota presents a Moon-Phase function.
The Moon-Phase is part of Miyota’s multi-function movement line-up. It is a function which shows the current phase of the moon, the changes to the image of the moon starting with the new moon. The crescent moon occurs three days after the new moon and the full moon occurs when the new moon is 15 days old. The full cycle of waxing and waning takes 29.5 days. The surface of the disc bearing the moon is driven by a 59-tooth wheel and completes two moon phases in one full rotation.
With the Sun & Moon function, the disc makes a full rotation in one day, the same as the 24-hour hand. The Moon-Phase requires highly-advanced processing technology to create 59 exact tooth gears in the 360 degree wheel. Miyota’s Moon-Phase movement captures the autumn moon in its watch design and makes moon-viewing available to everyone.
In addition to its great functionality, the Moon-Phase enhances the beauty of the watch design. Consider adding a Moon-Phase complication to your watch to prepare for the next autumn moon viewing!
