A New Rose Gold Alloy Introduced In The Constellation Sedna by Omega

By Meor Amri Meor Ayob

I am not into gold. So this particular piece does not appeal to me. Nevertheless, the new technology or chemistry interest me. Because of this, I’ve decided to highlight this particular watch to you. More about the alloy below, after the first set of pictures.


The OMEGA Constellation Sedna is the first watch to be crafted in 18K Sedna gold. This is a limited edition wristwatch. 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 timepiece has a polished case with a brushed bezel with Roman numerals. The watch is equipped with OMEGA’s Si14 silicon balance spring and the 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.


Sedna gold is the name OMEGA has given to a new alloy that 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.

Omega also mentioned that this alloy is patented. Interesting…
