Dial and Hands
The watch features a beautiful silver dial with a radiant sunburst finish that catches the light elegantly. The dial is furnished with applied baton hour markers featuring black onyx-style inserts, which provide excellent contrast and legibility. The matching baton hands also feature black inserts and show honest vintage patina and oxidation consistent with the age of the watch. A framed date window is positioned at the 3 o'clock mark, maintaining the dial's symmetry. The applied Omega logo and crisp "Seamaster Cosmic" script remain distinct.

Case and Crystal
The stainless steel case utilizes Omega's monocoque "front-loading" design, which eliminates the traditional removable caseback to improve water resistance and structural integrity. The case measures 35mm and retains its sharp, original geometry with defined edges and brushed surfaces. The caseback features a deeply engraved Seamaster Hippocampus medallion, along with the "Waterproof" and reference markings "166.026 - TOOL 107," all of which remain exceptionally crisp and legible. The crown is original and signed with the Omega symbol. The crystal is clean and offers a clear view of the dial.

Movement
Powering this timepiece is the highly regarded Omega Caliber 565, a copper-colored automatic movement often cited as one of the best vintage movements Omega ever produced. It features a quickset date function activated by pulling the crown to the outermost position. The movement has been serviced and is running exceptionally well, showing +2 to +5 seconds per day on the timegrapher, which indicates a healthy movement offering reliable vintage performance.

Strap
The watch is fitted with a new, high-quality black leather strap with a crocodile pattern embossed finish. The strap is supple and complements the dressy nature of the silver dial, secured by a steel pin buckle.

Condition
This timepiece is in excellent vintage condition. The specific design of the monocoque case has preserved the movement well, and the exterior steel shows only minimal handling marks while retaining its factory lines. The dial is clean and attractive, showing very little signs of aging, while the hands display a charming vintage character through natural oxidation. The engravings on the back are notably sharp, indicating the watch has seen careful wear over the decades.

Dimensions
With a diameter of 35mm excluding the crown, the watch sits comfortably on the wrist, offering a classic mid-century profile. The lug-to-lug length and the integrated style of the lugs give it a presence that wears slightly larger than the dimensions suggest, suitable for various wrist sizes.

Remarks
The Seamaster Cosmic reference 166.026 is a collector favorite due to its unique case construction and the presence of the Caliber 565. This particular example stands out due to its sharp case preservation and the excellent mechanical performance confirmed by timegrapher results. It represents the golden era of Omega's mechanical watchmaking before the quartz crisis, making it a valuable addition to any curated collection.

History
Omega introduced the Seamaster line in 1948 to celebrate the brand's 100th anniversary, basing the design on water-resistant watches made for the British military during WWII. The "Cosmic" name was added in the late 1960s to capitalize on the fascination with the Space Age, denoting a more modern and futuristic design language. This 1967 example embodies that transitional period, blending the rugged reliability of the Seamaster heritage with the sleek, forward-looking aesthetics that would define the era.
