    About This Watch

    Presented for sale by Second Vintage A captivating example of Omega's space-age design language, this Seamaster Cosmic combines robust engineering with an elegant, futuristic aesthetic. Recently professionally serviced and presented in spectacular visual condition, this timepiece offers a compelling opportunity for the discerning collector seeking a pristine, fully serviced, ready-to-wear classic. Brand: Omega Model: Seamaster Cosmic Reference Number: 166.026 Serial Number: 30372673 Movement: Caliber 565 automatic Dial: Silver sunburst crosshair dial in exceptionally clean, well-preserved condition Case Size: 35 mm Case Material: Gold-plated stainless steel Production Year: 1970 Condition: Stunning vintage condition with exceptionally preserved dial and crisp case lines Dial and Hands The dial of this Seamaster Cosmic is a masterclass in mid-century graphic design, featuring a brilliant silver sunburst finish intersected by a delicate black crosshair. The surface is exceptionally clean, entirely free of spotting, moisture damage, or discoloration, reflecting an outstanding level of preservation. Applied gold-tone faceted indices feature striking black inserts at the primary hours, perfectly matching the original gold-tone stick hands, which also carry black center stripes for enhanced legibility. An applied gold Omega logo sits proudly below the twelve o'clock position, complemented by crisp, flawless black typography for the Omega Automatic and Seamaster Cosmic scripts. The date aperture at three o'clock is elegantly framed by a stepped gold-tone window, completing this highly attractive and perfectly balanced dial configuration. Case and Crystal The distinctive 35 mm gold-plated monocoque case defines the Cosmic aesthetic, utilizing a front-loading unishell design intended to maximize water resistance. The case retains its sharp architectural lines, prominent faceted lugs, and the correct transition between its brushed and polished surfaces. The original gold plating, noted as 20 microns on the interior, remains rich and warm, showing only light, honest surface scratches consistent with careful vintage wear, primarily visible on the solid caseback. The reverse side features a deeply engraved Seamaster Hippocampus logo, alongside crisp "WATERPROOF" and "166026 - TOOL 107" factory markings. The watch is fitted with a signed Omega knurled crown and a clear domed crystal that perfectly magnifies the stunning dial beneath. Movement Powering this timepiece is the highly regarded Omega Caliber 565, a robust and beautifully finished automatic movement featuring a swan-neck regulator and a quickset date function. The movement displays Omega's signature copper-toned plating, which remains incredibly vibrant and clean. As evidenced by the provided disassembly imagery, the movement has recently undergone a thorough professional service and is running strongly. It is currently performing at approximately +5 to +8 seconds per day with excellent amplitude, making it not only collectible but immediately wearable with confidence. Strap The watch is paired with a handsome black textured leather strap, distinguished by prominent tan contrast stitching that handsomely complements the gold tones of the case and dial. The strap is in excellent condition and fastens with a classic gold-tone pin buckle. Condition This Seamaster Cosmic is presented in stunning vintage condition. The dial is near flawless, acting as the visual centerpiece of the watch. The gold-plated case remains thick and sharp, exhibiting only minor handling marks and superficial scratches commensurate with its age, with no significant dings or heavy wear to the plating. The recently serviced movement ensures excellent mechanical health, enhancing both reliability and long-term enjoyment. Dimensions Case Size: 35 mm Remarks Finding a Seamaster Cosmic with a crosshair dial in such pristine condition is a rare occurrence. The combination of its exceptional visual preservation, the highly desirable Caliber 565 movement, and the assurance of a recent professional service makes this a highly appealing and collectible offering for any Omega enthusiast. History Introduced in the latter half of the twentieth century, the Seamaster Cosmic line represented Omega's embrace of modernist, space-age design. Characterized by its innovative unishell case construction, the Cosmic was designed to offer superior protection against the elements by eliminating the traditional caseback seam. This model perfectly bridged the gap between a sophisticated dress watch and a durable everyday companion, solidifying its status as a beloved classic within Omega's storied Seamaster family. / Second Vintage SKU: OME-OSC-0012
