Omega Sedna

Sitting across several of Omega's core collections, the Sedna name does not denote a standalone line but rather identifies watches crafted from Omega's proprietary 18ct rose gold alloy. Introduced in 2012, Sedna gold is formulated with gold, copper, and palladium, which gives it a distinctively warm, reddish hue while improving resistance to fading over time compared with conventional rose gold.

Sedna pieces appear in collections such as the Constellation, De Ville, and Seamaster, typically occupying the upper tier of each family. The alloy is frequently paired with diamond setting, two-tone bracelets, and elaborate dials, making these watches a natural choice for buyers who want precious metal construction with a longer-lasting finish. Movements are drawn from Omega's standard range of Co-Axial calibres, so the Sedna designation speaks purely to material rather than any mechanical distinction.
