Omega Constellation C-Shape Day-Date Ref. 168.029 – Or Massif Elegance from 1969
A showcase of late-1960s Swiss luxury watchmaking, the Omega Constellation C-Shape Day-Date Ref. 168.029 combines precision engineering, refined materials, and timeless design. With its solid gold execution, signature C-shaped case, and rare Or Massif dial, this example offers collectors a perfect blend of mechanical pedigree and period style.
Gerald Genta’s Modernist Gold Vision
The 35mm C-shaped case, penned by legendary designer Gerald Genta, is rendered entirely in heavy 18K yellow gold, achieving a bold yet balanced wrist presence. The unpolished case retains its sharp lines, highlighting the sculptural nature of Genta’s modernist design language—a form that would go on to influence decades of watchmaking.
The star of the show is the rare OM-signed (Or Massif) dial, crafted entirely from solid 18K yellow gold with a sophisticated linen-textured finish. Applied gold hour markers, a matching Omega logo, and framed day-date windows at 3 o’clock complete the look—delivering both functional clarity and understated opulence.
Well-Preserved and Period-Correct
This example retains its original Omega-signed gold crown, ensuring authenticity and era correctness. The crystal has been replaced with a period-appropriate plexi glass, offering durability while maintaining the watch’s vintage profile. It is paired with a hand-made Belgian leather strap in rich brown, chosen to complement the warmth of the gold case.
Mechanical Excellence – Calibre 751
Inside beats the Omega Calibre 751, a refined automatic movement offering smooth day-date operation and excellent timekeeping. Known for its robustness and fine finishing, the 751 represents one of Omega’s most respected calibres from the era. The movement’s 28.7 million serial number dates production to circa 1969, placing it firmly within the golden era of Swiss mechanical watchmaking.
