Omega Constellation “C-Shape” Automatic – 18K Yellow Gold, OM Dial - Ref. 168.017 (Circa 1966)

A quintessential example of 1960s Omega design, this Omega Constellation C-Shape reference 168.017 combines bold mid-century aesthetics with exceptional technical pedigree. Crafted entirely in solid 18K yellow gold, including its coveted OM (Or Massif) dial, this watch is both a refined dress piece and a tangible investment, thanks to its remarkably high gold content.

Elegant, substantial, and unmistakably Omega, this is a Constellation that perfectly captures the brand’s golden era.

The Case – Iconic C-Shape in Solid Gold

Designed during the height of modernist watchmaking, the C-Shape case is one of Omega’s most recognizable and celebrated designs. Measuring 35 mm, it offers excellent wrist presence while retaining refined proportions ideal for a classic dress watch.

Executed in heavy solid 18K yellow gold, the case contains over 36 grams of gold, giving the watch a reassuring weight and unmistakable sense of quality. The case remains in beautifully preserved condition, with sharp edges and well-defined lines that speak to careful wear and minimal polishing.

The watch retains its original Omega crown, showing some light fading to the gold color—an honest and charming sign of age.

A plexiglass crystal completes the case, preserving the warm vintage character of the piece.

The Dial – Champagne OM (Or Massif)

The dial is a true highlight: a champagne-colored OM dial, crafted from solid 18K yellow gold. Subtle, luminous, and elegant, it reflects light beautifully and perfectly complements the gold case.

As expected from a Constellation, the dial design is balanced and refined, reinforcing Omega’s reputation for both precision and timeless aesthetics. The dial is well preserved and enhances the watch’s luxurious yet understated presence.

The Movement – Chronometer-Grade Excellence

Inside beats the legendary Omega Calibre 561, an automatic chronometer movement renowned for its robustness, accuracy, and longevity. This movement has just been serviced by our watchmaker and is keeping excellent time, ensuring reliability for daily wear.

The movement’s serial number 23,934,899 dates production to 1966, firmly placing this watch in the heart of Omega’s most celebrated era.

Strap – Handmade Elegance

The watch is fitted with a handmade leather strap from Belgium, offering comfort, quality, and a refined finishing touch that complements the watch’s classic dress character.
