Omega Seamaster Cosmic Automatic – Ref. 166.026 | Cal. 565:

⸻

A standout in Omega’s late 1960s lineup, the Seamaster Cosmic Ref. 166.026 features a sleek monocoque (front-loading) case paired with the highly respected Caliber 565 automatic movement. Known for its robust design and superior finish, the Cosmic model blends durability and refinement, ideal for everyday vintage wear. The clean silver dial with applied indices, central seconds, and quickset date function makes this piece both practical and collectible. Its distinctive tonneau case and elegant proportions make it a must-have for fans of retro Omega engineering.
