Crafted from exclusive 18K Canopus Gold™, the polished and brushed 39.4 mm case features distinctive faceted \"dog-leg\" lugs and a beautifully faceted bezel that reinterpret the design of the original 1952 Constellation. The stunning \"Pie-Pan\" dial, also fashioned from 18K Canopus Gold™, combines a crystal-finished center with opaline dodecagonal facets and eight hand-guilloché grooves, creating remarkable depth and elegance. Diamond-polished dauphine hands and redesigned kite-shaped indexes, all crafted from 18K Canopus Gold™, complete the refined display alongside the applied OMEGA logo and iconic Constellation star. A domed, bevelled sapphire crystal with anti-reflective treatment on both sides protects the dial, while the sapphire caseback reveals the magnificent Co-Axial Master Chronometer Calibre 8915. The movement is distinguished by its 18K Sedna™ Gold skeletonized rotor and balance bridge, enhanced by an applied Constellation Observatory medallion. Certified by METAS, the calibre delivers outstanding precision, resistance to magnetic fields up to 15,000 gauss, and a practical time-zone function, all supported by a 60-hour power reserve.\u003cspan class=\"PDq2pG_selectionAnchor\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003ch3\u003eTECHNICAL DATA\u003c\/h3\u003e\n\u003cp\u003e\u003cstrong\u003eMovement\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eOMEGA Co-Axial Master Chronometer Calibre 8915\u003c\/li\u003e\n\u003cli\u003eSelf-winding mechanical movement\u003c\/li\u003e\n\u003cli\u003eMETAS-certified Master Chronometer\u003c\/li\u003e\n\u003cli\u003eCo-Axial escapement with silicon balance spring\u003c\/li\u003e\n\u003cli\u003eTwin barrels mounted in series\u003c\/li\u003e\n\u003cli\u003eAnti-magnetic to 15,000 gauss\u003c\/li\u003e\n\u003cli\u003eTime-zone function\u003c\/li\u003e\n\u003cli\u003e18K Sedna™ Gold rotor and balance bridge\u003c\/li\u003e\n\u003cli\u003eFrequency: 25,200 vph (3.5 Hz)\u003c\/li\u003e\n\u003cli\u003ePower reserve: 60 hours \u003cspan class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eCase\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003ePolished and brushed 18K Canopus Gold™ case\u003c\/li\u003e\n\u003cli\u003eFaceted bezel and signature \"dog-leg\" lugs\u003c\/li\u003e\n\u003cli\u003e18K Canopus Gold™ \"Pie-Pan\" dial with crystal-finished center, opaline facets and eight hand-guilloché grooves\u003c\/li\u003e\n\u003cli\u003eDiamond-polished 18K Canopus Gold™ dauphine hands and kite-shaped indexes\u003c\/li\u003e\n\u003cli\u003eApplied OMEGA logo and Constellation star\u003c\/li\u003e\n\u003cli\u003eDomed, bevelled scratch-resistant sapphire crystal with anti-reflective treatment on both sides\u003c\/li\u003e\n\u003cli\u003eTransparent sapphire crystal caseback\u003c\/li\u003e\n\u003cli\u003eWater resistance: 30 m \/ 100 ft (3 ATM) \u003cspan class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eDimensions\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eCase diameter: 39.4 mm\u003c\/li\u003e\n\u003cli\u003eThickness: 12.23 mm\u003c\/li\u003e\n\u003cli\u003eLug-to-lug: 47.20 mm\u003c\/li\u003e\n\u003cli\u003eBetween lugs: 19 mm\u003c\/li\u003e\n\u003cli\u003eApproximate weight: 105 g \u003cspan class=\"\"\u003e\u003c\/span\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eStrap\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eDark blue alligator leather strap with grained calf leather lining\u003c\/li\u003e\n\u003cli\u003e18K Canopus Gold™ pin buckle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Omega","offers":[{"title":"Unworn \/ 2026","offer_id":48816924688616,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/0043\/2053\/files\/1_f47405cb-5182-439b-ac61-1a32109163f2.jpg?v=1785346266","url":"https:\/\/www.affordableswisswatchesinc.com\/products\/unworn-omega-constellation-observatory-ref-140-53-39-21-99-004-box-and-papers","provider":"Affordable Swiss Watches Inc.","version":"1.0","type":"link"}
