The Omega Seamaster Cosmic is a refined expression of mid-20th century Swiss watchmaking. Produced during the late 1960s and 1970s, the Cosmic line was designed with Omega’s hallmark durability and timeless elegance. This 40mm stainless steel case houses an automatic movement, highlighted by a clean silver dial with applied indices and day-date functionality at 3 o’clock.

The watch embodies the Seamaster tradition—robust, versatile, and understated—while the monocoque (front-loading) case construction offers superior water resistance for its era. The integrated lugs and gently curved case make it wear comfortably despite its larger vintage dimensions.

For collectors, the Seamaster Cosmic is a versatile piece: elegant enough for formal settings, yet built tough as part of Omega’s legendary Seamaster family.
