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.

Paid for new, received used.
Size: 9.5 Wide, Color: Cognac, Size: 9.5 Wide, Color: Cognac
Arrived dirty as if someone whore it for more than a few days. Maybe I was mistaken, but I saw nothing about “previously used” on the Amazon page. Returned it. I would suggest that the company use quality control when it comes to shipping. The shoes seem find otherwise. I ordered 9.5 and it was just a bit tight. If I reorder I will go for size 10.

Decent Shoes with Misleading Description (Not Leather)
Size: 12 Wide, Color: Black, Size: 12 Wide, Color: Black
I only look for leather when I’m purchasing dress shoes. Under the description “details” on this item it lists the shoe as leather upper and inner lining. A photo shows “genuine Napa leather lining”. If you keep reading (which I have now that I’ve received the shoes) it shows “faux leather” in the small print and that is not “leather”. I run a small leather business and this irks me because it’s clearly false advertising. The details also show the product is made in Brazil but when they arrived today, the shoe tag shows “Made in China” and “Man Made upper and lower”. I don’t hate the shoes. They look nice. What I know is they won’t hold up over time like leather, which is why the description should be accurate and not misleading.
