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.

So much sturdy fun for little dogs!
Size: Small 2"
Wow! My puppy loves these! He is entertained endlessly chasing after and nose scooting the little rubber balls! He really seems to enjoy the jingle sound and loves to chew on the balls also. Even with a lot of chewing from his little teeth, there are no marks. Sturdy, great toy!

Well made, perfect size!
Size: Small 2"
My dogs love these balls. They are the perfect size and hold up well for my 2 dogs, 7# and 9#. The bell is a nice change from the squeaky toys.

Durable, bouncy, not annoying like squeaky ball & our dogs LOVE them.
Size: Small 2"
Love these and my dogs love them to! Not nearly as noisy as a squeaky ball (thank goodness) and they bounce which are dogs love. They will fetch them, and they will play by tossing it up and pouncing on it when it bounces. They literally entertain themselves with it when we aren't playing fetch. Much more durable than the round rubber / latex squeaky ball / toys.
