This Omega Constellation from circa 1971 pairs compact, dress-oriented proportions with a two-tone gold-and-steel execution, including a fluted gold-tone bezel and integrated-style steel bracelet that reflect early 1970s design. The original silver-tone dial, applied gold-tone baton markers and framed date window maintain the model’s formal architecture while offering subtle contrast. Under the caseback medallion sits the calibre 1011, a high-beat automatic chronometer movement celebrated for precise timekeeping and user-friendly date setting. For a modern collector, this Constellation represents a refined, period-correct example of Omega’s transition toward 1970s aesthetics and mechanical quality.
