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 stainless steel features a bezel with engraved Roman Numerals, a crystal white silvery dial, and a round date window at the 6 o'clock position. The polished hour markers, hands, OMEGA logo and Constellation star are all in 18K white gold, while the Small Seconds subdial and Central Minute Track are circled by rings.Presented on the iconic mono-rang bracelet with a butterfly clasp and easy comfort adjustment, the timepiece is driven by the OMEGA Co-Axial Master Chronometer Calibre 8802, visible through the domed scratch-resistant sapphire crystal.
