History The Omega Constellation line has long represented the pinnacle of the brand's precision watchmaking, originally launched to celebrate Omega's numerous observatory chronometer records. By the late 1960s, the introduction of the C-shape case, penned by Gerald Genta, brought a modernized and architectural aesthetic to the collection. The Caliber 564 automatic movement inside was a highly regarded mechanism of the era, featuring a quickset date and robust chronometer-certified performance. This period of Constellation production remains highly valued by enthusiasts for its distinctive design and reliable engineering.
