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

This 34 mm model in 18K Sedna™ gold and stainless steel features a bezel with engraved Roman Numerals, a light chestnut dial, and a round date window at the 6 o'clock position. The incremental diamond hour markers are presented in 18K Sedna™ gold holders, while the Small Seconds subdial and Central Minute Track are circled by rings.

Presented on a taupe-brown leather strap, the timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8802, visible through the domed scratch-resistant sapphire crystal.
