History The Omega Constellation line was originally introduced in 1952 to serve as the brand's formal dress watch offering. This particular reference is powered by the chronometer-grade automatic caliber 564, celebrated for its signature copper-colored finish. To meet rigorous chronometer certification standards, the 24-jewel movement was adjusted to five positions and temperature. The caliber 564 also features a unique quick-set date mechanism, which is operated by repeatedly pulling the crown in and out, adding technical sophistication to a classic design.
