Omega Cosmic 18k Moonphase 1940s

Omega Cosmic Moonphase – 1940s

The Omega Cosmic was introduced in 1947 as the most prestigious model in Omega’s post-war catalogue — and this example shows exactly why. Housed in a medium size 34.5 mm gold case, it features a complete calendar with moonphase complication.

The elegant dial showcases day and month windows at the top (English language wheels), a moonphase within the sub-seconds at six, and a vibrant blue date track encircling the design. Combined with gold hands, a blue date hand, and the warm patina of time, this piece has undeniable charisma.

Preserved in beautiful original condition, this Cosmic wears large, both in size and presence. For collectors of vintage complication watches, this one is pure stardust.
