The dramatic and enduring design of the OMEGA Constellation Manhattan is characterised by its famous half-moons, “claws” on the case and iconic mono-rang bracelet.

In this 28 mm jewellery model, 18K Sedna™ gold has been used to create the case as well as the bezel with its subtle Roman numerals and 154 snow-paved diamonds. The white opal dial includes skeletonised hands and baguette-cut emeralds that are inspired by the Manhattan skyline.

Around the wrist, the 18K Sedna™ gold bracelet is set with 192 brilliant-cut diamonds and four Constellation “star cut” diamonds – all arranged in a shooting star pattern. At the heart of this timepiece is the OMEGA Calibre 4061, which is set behind an OMEGA Observatory medallion on the caseback.

SednaTM Gold

OMEGA has been using the exclusive 18K SednaTM Gold, its own fiery rose gold alloy, since 2012. Named after Sedna, an orbiting planetoid that has been described as one of the reddest in the solar system, SednaTM Gold not only bears all the standard characteristics of other 18K golds, but it also offers high resistance to the fading of colour and lustre over time. Its unique composition includes copper and palladium for colour and stability.

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.

The advantages
of this watch

When it comes to reliability there’s no matching a movement bound by natural law. This watch’s internal workings uses the very precise frequency signal of a quartz crystal to display time. The movement is powered by a battery and extremely accurate. What’s more it takes up minimal space, allowing for slimmer watch designs.
