Miyota 6P24

The Miyota 6P24 is a quartz movement assembled in Japan. It uses an SR621SW battery and claims accuracy of 20 seconds per month. The movement is 3.45mm thick with no jewels. Its distinguishing feature is a moonphase display at the 6:00 position, available in two dial variations—one with a dark background and white moon, the other with a navy blue background and yellow moon. It remains in production as the base caliber in Miyota's 6P family.
