Crafted from exclusive Platinum-Gold, the 39.4 mm case is paired with a black alligator leather strap and showcases a design inspired by the historic Geneva Observatory. The striking yellow dial is complemented by diamond-polished dauphine hands and distinctive kite-shaped indexes in 18K white gold with a 950 Platinum-Gold PVD coating, offering exceptional elegance and legibility. Through the sapphire crystal caseback, the exceptional OMEGA Co-Axial Master Chronometer Calibre 8915 is fully visible, featuring a luxurious 18K Sedna™ Gold skeletonized rotor adorned with an applied 18K white gold Constellation Observatory medallion, enhanced by dark blue aventurine glass and white opal enamel detailing. As the world's first two-hand movement to achieve METAS Master Chronometer certification, the calibre delivers remarkable precision, resistance to magnetic fields up to 15,000 gauss, and a convenient time-zone function without interrupting the movement. A domed, bevelled sapphire crystal with anti-reflective treatment on both sides ensures optimal clarity, while the watch offers a 60-hour power reserve and water resistance to 30 meters.\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 free-sprung balance and 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\u003e60-hour power reserve\u003c\/li\u003e\n\u003cli\u003eFrequency: 25,200 vph (3.5 Hz)\u003c\/li\u003e\n\u003cli\u003eFunctions: Hours, minutes \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\u003e39.4 mm Platinum-Gold case\u003c\/li\u003e\n\u003cli\u003eYellow dial\u003c\/li\u003e\n\u003cli\u003eDiamond-polished 18K white gold dauphine hands with 950 Platinum-Gold PVD coating\u003c\/li\u003e\n\u003cli\u003eDiamond-polished kite-shaped 18K white gold indexes\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)\u003c\/li\u003e\n\u003cli\u003ePresented in a special marquetry box with the Constellation Observatory emblem \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: 12.32 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: 121 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\u003eBlack alligator leather strap\u003c\/li\u003e\n\u003cli\u003ePlatinum-Gold pin buckle\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"Omega","offers":[{"title":"Unworn \/ 2026","offer_id":48816913055976,"sku":null,"price":0.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0521\/0043\/2053\/files\/1_95c36b8d-8d56-4583-9eca-f79e209c1130.jpg?v=1785345531","url":"https:\/\/www.affordableswisswatchesinc.com\/products\/unworn-omega-constellation-observatory-ref-140-93-39-21-99-001-box-and-papers","provider":"Affordable Swiss Watches Inc.","version":"1.0","type":"link"}
