About the Moon Phase Display in the Ref. IW503302:
The full moon has been steeped in mystery and legend since the beginning of time. It is undisputed that the moon’s gravitational pull controls the tides, and thus exerts a real influence on the earth and our lives. On the moon phase display, the moon is just 5 millimetres in diameter. Nevertheless, the depiction of its orbit on the miniature stage diverges by just 1 day in 577.5 years from the actual phase of the moon.
