The combination of a solid 18K gold case and deep black crosshair dial creates a striking contrast that feels both elegant and purposeful.\u003c\/p\u003e\n\u003cp data-start=\"215\" data-end=\"598\"\u003eThe early Constellation models defined Omega’s post-war identity. This example carries all the hallmarks that made the line iconic: applied gold hour markers, dauphine hands, the applied star above 6 o’clock, and the clean “Automatic Chronometer Officially Certified” text beneath the Omega logo. It is a strong and complete representation of a vintage Omega at its mid-century peak.\u003c\/p\u003e\n\u003cp data-start=\"600\" data-end=\"975\"\u003eIntroduced in 1952, the Constellation quickly became Omega’s flagship chronometer line. The caseback medallion featuring the Geneva Observatory and eight stars commemorates the brand’s chronometry achievements in observatory competitions. By 1956, references such as the 2852\/2853 SC had firmly established the aesthetic language that would define the collection for decades.\u003c\/p\u003e\n\u003cp data-start=\"1429\"
