Omega Constellation Double Eagle Perpetual Calendar 1513.51.00 – Cal.1680 – Black Dial – 38mm – Men Description / Features The Omega Constellation Double Eagle Perpetual Calendar Ref. 1513.51.00 is a sophisticated version of Omega's iconic Constellation, combining the distinctive Double Eagle design with a high-precision perpetual calendar quartz movement. The watch features a striking black dial with applied silver-tone hour markers, luminous hands and the famous Constellation star positioned above 6 o'clock. At 3 o'clock is a practical date display operated by Omega's Calibre 1680 high-precision quartz movement. Unlike a conventional date watch, this model features a perpetual calendar programmed to automatically account for months of different lengths and leap years, making it one of the more technically interesting quartz models within the Constellation collection. The Calibre 1680 is a thermocompensated high-accuracy quartz movement, designed to provide significantly greater precision than a conventional quartz movement. Another useful feature is the independently adjustable hour hand, allowing the local time to be changed without stopping the minutes and seconds — particularly convenient when travelling between time zones. The 38 mm stainless-steel case features the unmistakable Constellation design, including the characteristic claws and a brushed bezel engraved with Roman numerals. Combined with the integrated stainless-steel bracelet, the watch has a strong and substantial appearance on the wrist while retaining the refined character of the Constellation collection. The scratch-resistant sapphire crystal and 100-meter water resistance add excellent everyday practicality. A distinctive Omega combining the iconic Constellation Double Eagle design with the technical sophistication of a high-accuracy perpetual calendar movement.
