History Introduced in the late 1960s, the C-shape Constellation marked a distinctive shift in Omega's design language, moving away from the traditional pie-pan dials toward a more integrated, barrel-like geometry. This circa 1970 example houses the esteemed Caliber 751, a chronometer-certified automatic movement. Known for its robust architecture, the Caliber 751 utilizes a swan neck micrometer regulator and a self-compensating flat balance spring, ensuring the high precision expected of the Constellation family.
