History Introduced in the 1950s, the Omega Constellation quickly became the brand's flagship chronometer line, representing the pinnacle of their precision watchmaking. By the late 1960s, the collection evolved to include the distinctive C-shape case, a design widely attributed to the celebrated Gerald Genta. This era of the Constellation is prized by collectors for housing the 500-series calibers, which are widely regarded as some of the finest mass-produced automatic movements of the mid-twentieth century.
