    About This Watch

    Presented for auction by Second Vintage The late 1960s marked a period of profound design evolution for Omega, perfectly encapsulated by the Seamaster Cosmic line. Born during the height of the space age, this collection departed from traditional round cases, embracing futuristic tonneau shapes and innovative monocoque case constructions. This particular Seamaster Cosmic offers a compelling blend of robust everyday wearability and distinct retro-futuristic charm. Powered by one of Omega's most respected automatic calibers, it stands as a testament to the brand's mid-century engineering prowess and enduring aesthetic appeal. Brand: Omega Model: Seamaster Cosmic Reference Number: 166.026 Serial Number: 29054854 Movement: Automatic Caliber 565 Dial: Silver vertically brushed dial with applied indices, showing localized oxidation around the date aperture Case Size: 35 mm (excluding the crown) Case Material: Stainless Steel Production Year: 1969 Condition: Good vintage condition with honest signs of wear and localized dial aging Dial and Hands The watch features a silver dial finished with a refined vertical brushing technique that catches the light beautifully across its surface. It is appointed with applied faceted steel baton indices featuring black inserts, complemented by an applied Omega logo at the twelve o'clock position. The original baton hands mirror the indices with black detailing and luminous material. Upon close inspection, the dial exhibits distinct, localized oxidation and moisture staining immediately surrounding the stepped date aperture at three o'clock. There is also scattered, lighter spotting across the dial surface, and the black painted inserts on the hour and minute hands show visible signs of age-consistent flaking and degradation. The crosshair-style Seamaster Cosmic typography remains crisp and fully legible. Case and Crystal The 35mm stainless steel tonneau case showcases the classic c-shape profile that defined the era. The case retains a clear distinction between the sunburst brushed upper surfaces and the polished case flanks, displaying normal handling marks, light surface scratches, and softened edges consistent with decades of wear. The watch is fitted with a domed acrylic crystal that presents clearly with only minor surface wear. On the right side, the case is equipped with a period-correct, scalloped Omega signed crown. The solid caseback features a deeply engraved and well-preserved Seamaster Hippocampus logo alongside the Waterproof designation and the 166026 Tool 107 engraving, denoting the front-loading unibody construction designed to enhance water resistance. Movement Inside this monocoque case beats the highly regarded Omega Caliber 565 automatic movement, featuring a swan-neck regulator and a quickset date function operated by repeatedly pulling the crown. The copper-toned movement plates remain bright and visually clean, clearly displaying the 29-million serial number which dates production to approximately 1969. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. The timegrapher records a deviation of -10 to -19 seconds per day. Strap The watch is paired with a supple black leather strap accented by subtle blue contrast stitching. It is secured to the wrist with a vintage stainless steel pin buckle featuring the applied Omega logo, with the reverse side properly stamped with Swiss fabrication markings. Condition This timepiece is presented in good vintage condition. The stainless steel case remains structurally sound while exhibiting honest wear and light marks from regular use. The dial shows clear character and aging, most notably the concentrated oxidation bordering the date window and the degradation of the handset paint. The caseback engravings remain sharp and deeply defined, and the movement is remarkably clean and running with impressive precision. Dimensions The stainless steel case measures 35 mm in diameter, excluding the signed crown, offering a classic and comfortable vintage proportion that wears with distinct presence due to the tonneau geometry. Remarks The Seamaster Cosmic represents a fascinating chapter in Omega's rich history, offering collectors a unique blend of unconventional case design and superior mechanical reliability. Despite the visible aging on the dial, the exceptional performance of the Caliber 565 and the sharp caseback details make this a highly wearable and mechanically satisfying piece of mid-century horology. It is a watch that carries its history openly while continuing to function as a reliable daily companion. History Introduced in 1967, the Seamaster Cosmic was Omega's answer to the rapidly changing design language of the space age. Moving away from traditional multi-piece case constructions, Omega utilized a unibody, front-loading case design for the Cosmic line, significantly improving protection against moisture and dust. The tonneau shape provided a larger, more contemporary wrist presence while maintaining the robust, go-anywhere ethos of the Seamaster family. Today, the Cosmic is celebrated by collectors as a prime example of late 1960s retro-futurism, combining daring aesthetics with some of the finest mass-produced automatic movements Omega ever built. / Second Vintage SKU: OME-OSC-0002
