The Omega Constellation is one of the most storied lines in Swiss watchmaking, introduced in 1952 as Omega's standard-bearer for precision and elegance. Across more than seven decades the Constellation has earned its place on the wrists of icons, consistently balancing horological achievement with jewelry-grade aesthetics. Reference 131.58.29.20.55.002 represents the line's modern pinnacle, pairing the contemporary Co-Axial Master Chronometer movement architecture with materials and finishing that elevate it firmly into the realm of fine jewelry.

Sedna Gold is Omega's proprietary 18-karat rose gold alloy, engineered to resist fading and maintain its warm, rich hue far longer than conventional rose gold. The 29mm case in Sedna Gold offers a delicate yet substantial presence on the wrist, with the characteristic Constellation claws — the signature four-claw bezel feature — rendered here in the same Sedna Gold for a perfectly unified, precious look. Every curve and polished surface speaks to Omega's exacting standards of case finishing.

The dial is a genuine mother of pearl, a material prized for its unique, naturally occurring iridescence that shifts subtly with every movement of the wrist. Set with diamonds, the dial transcends mere timekeeping and becomes a wearable work of art. No two mother of pearl dials are ever exactly alike, lending each example of reference 131.58.29.20.55.002 an individuality that mass-produced dials simply cannot replicate.

Powering this Constellation is an Omega Co-Axial Master Chronometer movement, a caliber that has earned certification from METAS — the Swiss Federal Institute of Metrology — meeting the most stringent accuracy, magnetic resistance, and reliability standards in the Swiss watch industry. Master Chronometer certification means the movement has been tested to resist magnetic fields of at least 15,000 gauss, a level of protection that makes this watch exceptionally practical for modern daily life as well as a heirloom-grade timepiece.

The watch is presented on a leather strap that complements the warm Sedna Gold tones with understated sophistication, making it equally at home at a formal gala or an elegant afternoon occasion. Reach out to our team today and let us guide you through the purchase of this exceptional timepiece.

5. What is Sedna Gold and how does the mother of pearl dial look?
