About the Moon Phase Display in the Ref. IW503404:
The moon phase and its mirror image show the state of the moon in both the northern and southern hemispheres. For the first time with the IW503404, the double-moon model comes with the railway-track chapter ring typical of the Portugieser, while the designers have transformed the entire moon phase display into a star-studded night sky, so that the moon and stars appear to hover in infinite space.
