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

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

At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8800, visible through the domed scratch-resistant sapphire crystal.

**To achieve Master Chronometer status, it has passed the 8 rigorous tests set by METAS (The Swiss Federal Institute of Metrology)**
