The dramatic and enduring design of the OMEGA Constellation is characterised by its famous half-moons, as well as the “claws” on the side of the case.

This 39 mm stainless steel and 18K Sedna™ gold model features a bezel engraved with Roman numerals, a silk-embossed creamy silvery dial and a date window at the 6 o’clock position. The hands, OMEGA logo, Constellation star and indexes are all in 18K Sedna™ gold.

Presented on a brown leather strap, this timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal.

  • OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.
