Remarks This Constellation delivers a compelling mix of mid-century case architecture and a beautifully textured silver dial. The presence of the chronometer-certified caliber 1011 and the distinct observatory caseback medallion make it a highly capable example of Omega's flagship line. History The Omega Constellation was introduced in 1952 as the brand's premier chronometer collection, distinguished by the observatory medallion on the caseback representing precision records. In the 1960s, the line evolved significantly with the introduction of the C-shape case, a design that perfectly reflected the aesthetic shift of the era. The caliber 1011, utilized in the early 1970s, continued Omega's commitment to high-frequency chronometer performance, securing the Constellation's status as a capable mechanical timepiece. / Second Vintage SKU: OME-OCC-0067
