Complete with its original brick-link bracelet and a robust chronometer-certified movement, it is a highly capable and attractive collector timepiece. History The Omega Constellation has long been recognized as a flagship line of precision chronometers. In the late 1960s, the collection received a significant aesthetic update with the introduction of the C-shape case, penned by the renowned designer Gerald Genta. This fresh geometry moved away from the earlier pie-pan dials and dog-leg lugs, offering a more integrated, modernist profile that perfectly captured the era's evolving tastes. Powered by the highly regarded 500-series chronometer movements, these C-shape models remain a collector favourite for their distinctive design and reliable mechanical performance.
