Omega Constellation Ref. 166.0261 | Gold Dial | Fluted Bezel | Cal. 1020 | 1979

This late 1970s Omega Constellation sits right at the crossroads of elegance and everyday luxury. By 1979, Omega had fully leaned into bolder aesthetics, and this reference shows exactly how well they executed it. The gold dial, paired with a fluted yellow gold bezel, gives the watch a strong visual identity without tipping into excess.

The two tone bracelet blends stainless steel with yellow gold, grounding the watch and making it versatile enough for regular wear. It feels confident on the wrist, not flashy, not shy. The Constellation star at six reminds you that this line still carried Omega’s chronometer heritage, even as design language evolved.

Inside is the automatic Calibre 1020, a slim, efficient movement from Omega’s in house lineup. It was designed for reliability and daily use, keeping the case profile refined while delivering solid performance. This is a watch meant to be worn, not kept hidden away.

Historical Significance

By the late 1970s, the Constellation had evolved from purely conservative chronometer watches into refined luxury daily wearers. References like the 166.0261 reflect Omega’s response to changing tastes, combining precious metals, bold dials, and slimmer automatic movements. The Calibre 1020 played an important role in this transition, offering dependable performance in a more modern package. Today, these gold and two tone Constellations appeal to collectors who appreciate the bridge between classic Swiss watchmaking and late twentieth century style.
