This classical beauty represents a special interpretation of our rotating 3-dimensional real moon indicating the true moon phase. The moon rotates around the earth every 29,530588853 days. Our hand-made 3D miniature moon indicates the moon phase so accurately that it deviates only one day in 11.000 years. It is the most accurate 3D moon phase in the world ever incorporated in a mechanical watch. The watch also shows the time. And who needs more?
