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 Constellation 2009 model features a white mother-of-pearl dial with diamond-set indexes, a date window at the 3 o'clock position and a scratch-resistant sapphire crystal. The bezel, with its engraved Roman numerals and 18K yellow gold claws, is mounted on a 27 mm stainless steel case and is presented on a stainless steel bracelet.

At the heart of this timepiece is the Co-Axial calibre 8520, visible through the transparent caseback.
