        If I pretended not to understand your question, Jim, I could take this very far ...but I know you probably mean the moon-phase

        It's an astronomical complication that consist of a rotating disc that is geared to complete revolutions in synodic periods, or lunation, of approximately 29.5 days. While the Date wheel tick over at midnight (two complete rotations of the hour hand), the moon-phase disc rotates fractionally faster. Here's how it's used:



        (From Seiko Analogue Quartz 7A48 Instructions)

        Notice also that on Pete's 7A48. The sub-dial at 12 accommodates two complications (Date and Moon-Phase) that share a common axis, but rotates at different rates. 8-)

        Moon-Phase is, I guess, a relic of the past when watchmaking had a close tie to astronomy, especially that of the movement of celestial bodies.
        A watch journey that also serves the betterment of others is one worth taking.
