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.
