Constellation Co‑Axial Chronometer 27 mm

The especially dramatic and enduring design concept of the OMEGA Constellation line is characterized by its famous “Griffes”, or claws, and striking dials.

This brushed model features a champagne dial decorated with a supernova pattern, marked with diamond-set indexes and covered by a scratch-resistant sapphire crystal. The diamond-set bezel is mounted on a 27 mm 18K yellow gold case, and is presented on an 18K yellow gold bracelet.

At the heart of this timepiece is the OMEGA Co-Axial calibre 8521, visible through the transparent caseback.
