Omega Constellation Co-Axial Master Chronometer 29 mm Yellow Dial (131.50.29.20.58.001)

Description

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 29 mm 18K yellow gold model features a bezel engraved with Roman numerals, sun-brushed champagne dial with diamond hour markers and a date window at the 6 o’clock position. The bracelet, hands, OMEGA logo, Constellation star and diamond holders are also in 18K yellow gold.

At the heart of this timepiece is the OMEGA Co-Axial Master Chronometer Calibre 8701, visible through the domed scratch-resistant sapphire crystal.
