The Omega Seamaster Cosmic reference 166.036 is a vintage automatic wristwatch introduced by Omega in 1967. It belongs to the Seamaster line and represents a classic mid-century combination of dress and sports watch aesthetics.
The watch features a stainless steel case measuring approximately 35–36 mm in diameter. Its most distinctive element is the one-piece Unishell construction, which is opened from the dial side rather than the caseback, providing enhanced water resistance rated to 30 meters. The case has a slim profile, a satin-finished bezel, and polished sides, giving it an elegant yet understated appearance.
It is powered by the Omega Caliber 752 (or the closely related Caliber 762 in some examples), a reliable automatic movement that beats at 19,800 vibrations per hour. Many examples are chronometer-rated, and the movement includes quick-set day and date complications displayed at the 3 o’clock position.
Dials are typically two-tone or silvery gray, featuring applied indexes, luminous hands, and the characteristic Seamaster Cosmic branding. The watch is fitted with a plexiglass crystal, which in some cases includes an internal cyclops-style magnifier over the date window.
Produced primarily from the late 1960s to the early 1970s, the 166.036 remains a sought-after model among collectors for its clean design, solid build quality, and historical significance within Omega’s Seamaster collection.
