Constellation Omega Co‑Axial 27 mm
Steel on steel

Description
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 black dial decorated with a supernova pattern, marked with diamond-set indexes and covered by a scratch-resistant sapphire crystal. The bezel, with its engraved Roman numerals, is mounted on a 27 mm stainless steel case, and is presented on a stainless steel bracelet.
This timepiece is powered by the OMEGA Co-Axial calibre 8520, visible through the transparent caseback.
