Brand: Omega Model: Seamaster Cosmic Reference Number: 165.023 Serial Number: 26305064 Movement: Omega Caliber 552, 24 Jewels, Automatic Dial: Silver sunburst dial with applied gold-tone indices, displaying an exceptionally clean surface with minimal age-related wear Case Size: 34 mm (excluding the crown) Case Material: Gold-plated over base metal Production Year: 1968 Condition: Fair vintage condition with a beautifully preserved dial and heavily worn case Dial and Hands The silver sunburst dial remains in remarkably well-preserved condition, reflecting light beautifully across its textured surface. It features applied gold-tone faceted indices with black central inserts, complementing the applied Omega logo at twelve o'clock. The crisp black typography for the Omega Automatic and Seamaster Cosmic branding remains perfectly legible, with no signs of print loss. The gold-tone hands, complete with matching black inserts and aged luminous material, show gentle oxidation consistent with their age. The dial surface is highly attractive, presenting only very faint, microscopic signs of even aging under close inspection, maintaining an elegant and refined appearance. Case and Crystal The front-loading monocoque case exhibits clear and honest signs of its vintage journey. Originally finished with a 20-micron gold plating, the case shows significant plating loss, particularly on the lug edges, case flanks, and extensively across the reverse side, revealing the brass base metal beneath. Despite this heavy surface wear, the distinctive tonneau-shaped silhouette and sweeping lug profile remain structurally intact. The watch is fitted with a domed acrylic crystal that presents clearly, protecting the dial while enhancing the vintage aesthetic. The Omega-signed crown remains present, showing wear consistent with the rest of the case. Movement Powering this Seamaster Cosmic is the esteemed Omega Caliber 552, a 24-jewel automatic movement renowned for its durability and precision. The copper-colored movement plates and rotor present beautifully, showcasing the fine finishing characteristic of Omega's golden era. Close inspection reveals the caliber marking 552 and the serial number 26305064, confidently dating the watch to 1968. Exhibiting remarkable accuracy and consistency, performing brilliantly for a vintage timepiece. The timegrapher result indicates a performance of +9 to +15 seconds per day. Strap The watch is paired with a brown leather strap featuring a crocodile-embossed pattern and matching stitching. The strap exhibits signs of wear and creasing, complementing the heavily patinated character of the watch case. It is secured with a standard gold-tone pin buckle. Condition This timepiece is presented in fair vintage condition overall, defined by a stark contrast between its components. The dial and movement are exceptionally well-preserved, showcasing the enduring quality of Omega's interior craftsmanship. Conversely, the exterior case exhibits heavy vintage wear, with substantial gold plating loss and brassing across the reverse and edges, telling the story of decades of faithful wear. Dimensions The case measures 34 mm in diameter excluding the crown, offering a classic vintage profile that wears elegantly on the wrist. The integrated case design provides a comfortable and historically accurate presence.

History Introduced in the late 1960s, the Seamaster Cosmic line represented Omega's push toward modern, streamlined aesthetics combined with practical engineering. The use of a unishell or monocoque case was a deliberate design choice intended to minimize potential points of moisture ingress, creating a more robust everyday timepiece. Housing some of Omega's most reliable in-house calibers, the Cosmic series remains a beloved and historically significant sub-collection within the legendary Seamaster family.
