From Omega, the pinnacle manufacture of Swiss precision horology, this is the distinguished Omega Constellation Octagonal Two-Tone Quartz, conceived during the late 1970s and early 1980s integrated-bracelet luxury design era. Featuring a geometric octagonal stainless steel case, a vertically brushed gold-toned accent bezel, the deeply embossed Geneva Observatory & 8 Stars medallion on the caseback, a factory-original integrated stainless steel link bracelet with gold Omega clasp branding, an authentic gold-toned setting crown, and driven by an accurate Swiss-made in-house Omega quartz movement, this timepiece provides an elegant, jewelry-grade vintage presence on the wrist. ​Case Dimensions & Construction ​Case Dimensions: Approximately 28 mm across excluding the winding crown (approx. 29.5–30 mm including crown / 32–33 mm vertical lug-to-lug stance). With its slim geometric profile and anatomical integrated-bracelet curve, it offers a remarkably comfortable, refined, and classic dress fit on ladies' wrists or for collectors who favor compact vintage proportions. ​Case & Bezel Condition: Solid stainless steel monobloc case construction topped with a vertically brushed circular gold-toned bezel ring set into the octagonal frame. Reflecting over 40 years of age and gentle past wear, honest vintage hairline scratches, small contact marks, and light surface rubbing are present across the case flanks, bezel rim, corners, and facets. ​Crystal: Flat mineral/sapphire crystal. Superficial hairline scratches and minor vintage contact marks consistent with age may be visible on the crystal face. ​Setting Crown: Original gold-toned crown at 3 o'clock featuring a dark center cabochon/dot accent. ​Caseback: Original solid stainless steel snap-on caseback. The outer center cleanly displays the high-relief Geneva Observatory medallion surrounded by eight stars, preserved in crisp and well-defined relief. ​Dial & Details ​Dial Condition: 100% factory-original (unrestored / non-redial) dark navy / black vintage Constellation dial. ​Patina & Ageing: The dial remains completely authentic; honest age-related speckling, spotting, natural tonal shifts, and a fine "stardust" vintage patina are visible across the dial plate. ​Appointed Details & Hands: Adorned with the applied gold-toned Omega emblem and cursive "Constellation" script below 12 o'clock, "OMEGA QUARTZ" above 6 o'clock, and "- SWISS MADE -" along the lower track. Fitted with applied gold-toned baton hour markers and a matching minimalist gold hand set. ​Movement, Bracelet & Clasp ​Movement: Authentic Swiss-made, high-precision in-house Omega quartz caliber. Timekeeping is precise, steady, and operates as intended. ​Original Integrated Bracelet: Factory-original solid stainless steel Omega block link bracelet tailored specifically to the case (clasp reference 795.0800). The folding clasp is decorated with an applied gold-toned plaque bearing the Omega hallmark on the exterior, while the inner folding blade is stamped "STAINLESS STEEL - OMEGA (in triangle) - 7950800". ​Wrist Sizing: The watch and bracelet accommodate a wrist circumference of up to approximately 15.5 cm (approx. 6.1 inches). ​Please Note: Vintage two-tone octagonal Omega Constellation references remain iconic representations of Swiss integrated luxury sport-dress design from the turn of the 1980s. Age-appropriate hairline scratches on the case and crystal, the natural dial patina/spotting, and the 15.5 cm bracelet size. Due to its vintage nature, no water resistance warranty is provided.
