Omega Constellation C-Shape Ref. 168.017 is one of those vintage pieces that perfectly captures the transition from classic round cases to more modern, integrated silhouettes. Released in the late 1960s, this model is part of the iconic “C-shape” family designed by the legendary Gerald Genta. The rounded-square case — shaped like a soft "C" — marked a bold shift in Omega’s design language and set the stage for many of the integrated sports watches that followed. What makes this particular piece stand out is its black dial, a rarer configuration compared to the usual silver variants. Paired with applied silver baton indices and slim hands, the dial offers a sleek, almost formal aesthetic. The signature Constellation star sits proudly above 6 o’clock, and the day-date complication adds practicality without disrupting the clean design. Inside, the watch is powered by Omega’s in-house automatic Caliber 751, known for its smooth sweep and reliable performance. This chronometer-rated movement is hidden behind a screw-down case back featuring the famous Observatory medallion — a hallmark of Omega’s pursuit of precision.
