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 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 31 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.
