HANDS-ON : Omega’s new Constellation Sedna and its new 18K rose gold alloy


Following on from my posts about Omega’s new 2013 offerings of the Bullhead and the Speedmaster ‘Dark Side of the Moon’ is a third post about one of Omega’s other big announcements for the year, the new Constellation Sedna, made using a new 18k rose gold alloy.

Deriving its name from a trans-Neptunian object of the same name, Sedna™ is the name Omega has given to a new alloy of gold, copper and palladium that was developed by the Swatch Group. It has a minimum gold content of 75 per cent and its rose colour is a result of the balance of the metals in the alloy. The inclusion of palladium is to ensure that the red gold of watches using this alloy won’t fade over time. The surface of the orbiting object after which the alloy is red, hence the alloy’s colour.


It has a polished case with a brushed bezel with Roman numerals, indices and hands also made of 18K Sedna gold, as is the clasp on its strap. The dial is a silver grained version of the famous “pie-pan” style of the early Constellations. All logos on the dial, including the Constellation star, are applied Sedna gold to match the case, as are the polished arrowhead markers.

The Constellation case has a wide bezel, four claws and whilst featuring this signature bezel, the contemporary Constellation Sedna case is, at 38mm, larger, thicker and more bold, clearly in the style of its predecessors. It is water resistant to 10 bar (100 metres / 330 feet).


This new model uses the OMEGA Co-Axial calibre 8501, visible through a sapphire crystal case back and with a rotor and balance bridge in solid 18k gold.

The Constellation Sedna will be produced in a limited edition of 1,952 pieces after the year of the Constellation’s debut. It comes in a special wooden presentation box with a rose-coloured lining.


Of the three new Omega 2013 models that I have blogged about, the one that speaks to me the most is the Bullhead. The new Sedna will appeal particularly to Constellation (and pie pan dial fans); it is a beautifully made watch with a clean elegant dial. The case is attractively finished, especially the brushed bezel with four polished claws.
