The moon phase on your wrist.

The moon phase plate, which takes 59 days to complete one revolution (29.5 days for half a revolution), rotates so that you can observe the changing phases of the moon on your wrist, whether a full moon, crescent moon, first quarter or third quarter moon.

※The rotation of the moon phase plate is subject to slight deviations and should be manually adjusted on a regular basis.

The lunar calendar,
based on the moon phase cycle

The solar calendar (Gregorian calendar) that we use today is based on the time taken for the Earth to orbit once around the sun, representing one year.
The lunar calendar, on the other hand, has been in use since before the common era, and was used in Japan until the Meiji period (about 150 years ago). With this calendar, a month is the time taken for the moon to complete one lunar cycle, from a new moon to a full moon, and back again. The moon phase mechanism visually represents the movement of the moon, which has been closely associated with people’s lives since ancient times.

An attractive design pair with different expressions
