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 brown dial decorated with diamond-set indexes and a date window at the 3 o’clock position, and covered by a scratch-resistant sapphire crystal. The diamond-set bezel is mounted on a 38 mm 18K red gold case, and presented on an 18K red gold bracelet.

The OMEGA Co-Axial calibre 8501, visible through the transparent caseback, powers this exquisite timepiece.

    Sapphire Crystal

Red Gold

Gold in its pure form (24K) is slightly reddish yellow and very soft. It is usually alloyed with other base metals for a diverse variety of uses. Considered to be the premium standard in watch and jewellery making, 18K gold (with at least 75% pure gold) provides the ultimate balance between purity and usefulness. Traditional 18K red gold is alloyed with copper-silver and offers an excellent resistance to corrosion, while being highly bio-chemically inert. It provides a beautiful hue that suits wearers even with sensitive skin.

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.

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.
