The Speedmaster Moonphase builds upon this remarkable legacy by incorporating a sophisticated astronomical complication that displays the changing phases of Earth's closest celestial companion.

Unlike conventional moonphase watches that use stylized representations of the Moon, Omega employs a specially microstructured metallic crystal disc displaying two exceptionally detailed lunar images.
