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 model features a white mother-of-pearl dial with a date window at the 3 o'clock position, diamond-set indexes and a scratch-resistant sapphire crystal. The bezel, with its engraved Roman numerals, 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 OMEGA Co-Axial calibre 8520, visible through the transparent caseback.

Stainless Steel

Stainless steel is certainly the most conventional of watchmaking materials for outer craftsmanship, and offers beauty, strength and affordability. OMEGA uses 316L stainless steel. Known for its corrosion-resistance and high lustre after polishing, this material is often the ideal choice for watches in both daily-use and high-stress situations such as diving and adventure.

Diamonds

Diamond is recognised as the hardest material on Earth, graded 10 on the Mohs hardness scale, and is the only gem made entirely of carbon. In nature, it can only be formed under high temperature and pressure conditions that exist within a specific depth range (~100 miles) beneath the Earth's surface. To decorate its timepieces and jewellery, OMEGA uses "Top Wesselton" white COLOUR diamonds with CLARITY ranging from pure to VVS (Very Very Small inclusions). Along with choosing the best weight in CARAT, the CUT is also carefully selected in order to maximise brightness and scintillation. It goes without saying that OMEGA is a certified member of the non-profit Responsible Jewellery Council (RJC), assuring customers that its processes involving people, materials and the environment are ethical and fair.

Mother-of-pearl

Also known as "nacre", mother-of-pearl is an organic-inorganic composite material produced by some molluscs as an inner shell layer, similar to pearls. It is strong, resilient and iridescent, with changing colours depending on the wavelengths of light at different viewing angles. Produced with exquisite skill and delicacy, OMEGA's ladies' collection offers mother-of-pearl dials of top quality, enhanced with specific attributes.

Sapphire Crystal

To really appreciate the finer details of a timepiece, OMEGA uses synthetic sapphire crystal with a highly scratch-resistant and anti-reflective treatment. Before the machining and finishing processes take place, the sapphire crystals are produced under the Verneuil process, also called flame fusion. It involves the melting of the raw substance using oxyhydrogen flame and the crystallisation of the melted droplets to form a cylinder. Graded 9 on the Mohs-hardness scale (graded 1-10), the resulting sapphire crystals are virtually scratch-proof and very hard, ensuring an unhindered vision at all times.
