WHAT WE LOVE:

The Omega Seamaster Cosmic 165.023 is a quintessential product of the late 1960s, combining a sleek, monocoque (one-piece) case design with a no-frills, elegant dial layout. This reference is known for its seamless, modernist look — designed to be both dressy and practical, with a resilient case construction and timeless proportions.

This particular example features a silvery dial with block baton indices and hands, framed by a domed acrylic crystal. The tonneau case gives it a refined silhouette. Whether you're drawn to vintage Omega or just appreciate clean mid-century design, the Seamaster Cosmic makes a strong case for daily wearability.

WHAT’S INSIDE:

Inside beats the Omega Calibre 550, a workhorse automatic movement from the era with no date complication (for this ref). It’s accessed via front-loading service (through the crystal), typical of the monocoque Seamaster cases. With proper servicing, this movement offers decades of reliable timekeeping.
