Omega Constellation Automatic Ref. 166.052 – 18K Yellow Gold Chronometer (1969)

The Omega Constellation Ref. 166.052 represents the height of Omega’s late-1960s craftsmanship—where precision, luxury, and modernist elegance converged. Produced in 1969, as indicated by its 30-million-range serial number, this solid 18K yellow gold chronometer captures the essence of Omega’s golden era in both form and function.

The Case – Solid 18K Gold with Architectural Poise

Crafted from solid 18K yellow gold, the 34 mm case exudes quiet sophistication and tactile richness. The defining feature is its fluted bezel, among the most finely executed of any period Constellation—its delicate ridges form an almost woven texture that shimmers subtly with movement. The case’s proportions are balanced and confident, with a reassuring heft that speaks to the density and purity of its gold construction.

The back bears the signature Observatory medallion, Omega’s emblem of precision, surrounded by eight stars—a tribute to the brand’s record-breaking chronometer trials. Crisp hallmarks and sharp lugs confirm the watch’s careful preservation and authenticity.

The Dial – Refined Silver Simplicity

Under its Omega-signed plexiglass crystal, the original silver dial remains an immaculate study in balance. Gold hour markers and the applied Omega logo add depth and warmth, while the discreet date aperture at 3 o’clock integrates seamlessly into the design. Every element is purposeful—restrained yet undeniably elegant.

The dial proudly reads “Omega Automatic Chronometer Officially Certified,” a mark of its verified accuracy, with all print crisp and evenly preserved. The result is a timeless face—minimalist, legible, and unmistakably mid-century Omega.

The Movement – Omega Caliber 1001 Chronometer

At its heart beats the Omega Caliber 1001, an automatic, chronometer-certified movement featuring a quick-set dateand an ultra-thin profile. This 24-jewel calibre was engineered for high precision and smooth performance, embodying Omega’s technical ambition just before the quartz era.

This example has been recently serviced, ensuring accurate timekeeping and effortless winding. The Cal. 1001 remains a testament to Omega’s mechanical mastery during one of its most innovative decades.

The Strap – Modern Comfort, Traditional Craft

The watch is fitted with a brand-new, hand-stitched leather strap made in Belgium—a supple, elegant complement to the watch’s golden case. Its warm tones and refined finishing ensure it sits comfortably on the wrist, enhancing the understated luxury of the piece without drawing attention away from its vintage charm.
