The OMEGA Constellation Sedna is the first watch to be crafted in 18K Sedna™ gold. This limited edition wristwatch seamlessly blends the timeless aesthetic appeal of a legendary watch family with the world premiere of an innovative material.

Sedna™ gold is the name OMEGA has given to a new alloy that stunningly blends three elements: gold, copper and palladium. It is an 18K rose gold, meaning that it has a minimum gold content of 75%. Sedna™’s unique rose colour is a result, in part, of just the right proportion of copper: Its palladium content helps to ensure that the reddish hue of Sedna™ gold will be particularly long lasting. It takes its name from a trans-Neptunian object which astronomers called Sedna – the same name as an Inuit goddess who is said to live at the bottom of the Arctic Ocean. The surface of the orbiting object has been described as one of the reddest in our Solar System.

Swatch Group assembled a team of top metallurgists and scientists from several of its companies with the shared goal of creating an 18K rose gold alloy whose colour would be not only beautiful but enduring. Sedna™ gold – developed 100% in house by the Swatch Group team – is the patented, breath-taking confirmation of their success.  

The OMEGA Constellation Sedna is the first watch to be crafted in 18K Sedna™ gold.  This limited edition wristwatch seamlessly blends the timeless aesthetic appeal of a legendary watch family with the world premiere of an innovative material. 18K Sedna™ gold, a patented alloy blending gold, copper and palladium, has been created to ensure that the unique rose gold lustre of the watch case will be especially long-lasting. The indexes and hands are also made of 18K Sedna™ gold, as is the clasp on its strap.

The distinctive timepiece has a polished casebody with a brushed bezel emboldened by tone-in-tone Roman numerals. It has a luxurious silvery “pie-pan” dial inspired by that of the very first Constellation launched in 1952. The timepiece is presented on a strap crafted from fine brown leather. The watch is equipped with OMEGA’s innovative Si14 silicon balance spring and the industry-changing OMEGA Co-Axial calibre 8501, visible through a sapphire crystal caseback. The OMEGA Constellation Sedna is water resistant to 10 bar (100 metres / 330 feet).

The OMEGA Constellation Sedna will be produced in an edition limited to 1,952 pieces, signifying the year OMEGA debuted the renowned Constellation watch family. It is delivered in a special wooden presentation box with a rose-coloured lining. The watch has a full four-year warranty.
