THE WATCH

This is a 1966 Omega Constellation Automatic reference 167.021, featuring a gracefully contoured 33mm stainless steel case. Its curved profile hugs the wrist, with flat-ended tapered lugs extending to a lug-to-lug length of 39mm and a remarkably slim 7mm thickness. The case gently tapers toward the lugs for a refined silhouette, while a coin-edge crown sits neatly on the right side. Framing the watch is a slim, polished bezel that secures a domed crystal above a striking sunburst silver dial. An outer minute track encircles applied baton hour markers, each accented with Tritium lume pips. Slender pencil hands and a fine, tapered sweeping seconds hand complete the elegant display. At 12 o’clock, crisply printed text reads “Omega Automatic Chronometer Officially Certified,” while “Constellation” and an applied star adorn the lower half of the dial at 6 o’clock, underscoring its classic dress watch pedigree. Turning the watch over reveals a screw-down case back, embossed with the iconic Constellation Observatory medallion surrounded by eight stars. Powering the watch is Omega’s ultra-thin automatic Calibre 712—featuring 24 jewels and operating at 19,800 beats per hour. This movement, the thinnest automatic Omega ever produced, was in use from 1967 to 1976.

A BIT OF TRIVIA

Omega first introduced the Constellation in 1952, at the time it was Omega's flagship timepiece, the first models had a Cal. 354 bumper movement in them. Later in 1955, Omega introduced the Automatic Cal. 50x, followed in 1959 by the Cal.55x (no date) and 56x (date) versions. Many of the Constellations came with pie-pan dials, diamond indexes, and fancy lug configurations, and all the gold Constellations of that time had the Observatory of Geneva's hand engraved on the back. The stainless steel and stainless steel/gold versions had a gold medallion on the back with the Observatory of Geneva, the eight stars above the Observatory stand for the many exploits of Omega in the world Chronometer competition, celebrating the fact that all Constellations are Chronometer Certified. In 1964, Omega introduced its first Constellation with the “C” case, due to the case resembling two mirrored Cs, the “C” case was a modern move away from the popular round Constellations of the 1950s.

OUR THOUGHTS

The Omega 167.021 is a beautifully understated example of vintage elegance, and what I love most about it is how effortlessly refined it feels. Its ultra-thin case, powered by the impressive Caliber 712, wears incredibly well—slipping under a cuff with ease while still making a quiet statement. The minimalist dial and clean lines reflect Omega’s mid-century design language at its best. It’s not flashy, but there’s real substance and craftsmanship here, making it a perfect dress watch with timeless appeal.
