What Is Omega Sedna Gold?

In their endless search for the best materials to use for their watches, watch brands have created their own secret formulas to produce metals that they can call their own.

In the case of Omega, they have been producing their own brand of 18k rose gold since 2013 – the Omega Sedna Gold. After making its entrance within the Constellation collection, the reddish rose gold can now be seen across all Omega collections, including the Seamaster and Speedmaster.


What sets the Omega Sedna Gold apart from other rose gold? Here’s a closer look.

What Is Omega Sedna Gold?

Traditionally, rose gold is created using a delicate mixture of classic yellow gold, silver, and copper metals. As beautiful as it is, however, standard 18k rose gold tends to lose its reddish hue over time, as the copper atoms are dissipated from the alloy.

To remedy this, Omega used the rare and more precious metal palladium in place of silver. The result was not just a unique shade of rose gold, but also an incredible resistance to discoloration and fading.

Sedna Gold takes its name from a body in space that orbits our Sun, at a greater distance than the planet Neptune. Its surface has been described as the reddest in the Solar System, inspiring the reddish hue of the Sedna Gold.

Moreover, Sedna Gold is not just refreshingly beautiful and different, it is also said to be lighter on the wrist.

Developed 100% in house, Sedna Gold is actually patented by the Swatch Group, Omega’s parent company. They hired metallurgists and scientists from their companies and gave them the shared goal of creating an 18k rose gold alloy.

While it’s mostly used by Omega, Blancpain –  which is also a Swatch Group company, actually released a Sedna Gold version of their iconic Fifty Fathoms Bathyscaphe watch in 2015.



Omega’s Patented Gold Alloys: Moonshine and Canopus

Sedna Gold is undoubtedly Omega’s most popular patented alloy, and also its most frequently used one. With Sedna Gold’s success, Omega has actually added new proprietary alloys to its stable – the Moonshine and Canopus Gold.

In 2015, Omega developed their own 18k white gold alloy called Canopus. It is composed of gold, palladium, and smaller quantities of platinum and rhodium, possessing the characteristics of standard 18k golds, while also distinguishing itself for its high brilliance and longevity.

The alloy is named after the bright star Canopus, which is 71 times bigger and 10,000 times brighter than the sun.

In 2019, they launched their proprietary 18k yellow gold called Moonshine, in time for the 50th or golden anniversary of the Omega Apollo 11. With a mixture of gold, copper, silver, and palladium, they created a material that is more durable than regular 18k yellow gold, yet softer, paler and less yellow – just like the moon’s soft glow.



With outstanding durability and refreshing hues, Omega’s constellation of metals are the perfect alchemy of beauty and longevity.
