1950s Omega Rare “Square Cosmic” 18K PG Triple Calendar Moonphase


1950s Omega “Square Cosmic” 18 carat pink gold model. It is equipped with a late model movement Cal.381 with a triple calendar moon phase function. It has a square case, which is very rare in the Cosmic series where round cases are often seen. Despite its 32mm diameter, the square case and fancy lug design have an overwhelming presence, and the square dial with its triple calendar and moon phase function is a very rare example of a wonderfully vintage-inspired timepiece. The square cosmic is also available in yellow and pink gold, 18 and 14 carat gold, but this one is a rare 18 carat pink gold model.
