Description

Handcrafted by a select group of horologists at OMEGA’s Atelier Tourbillon in Switzerland, this extraordinary timepiece is OMEGA’s first-ever manual winding central tourbillon to be Master Chronometer certified.

Cased in a blend of 18K Sedna™ gold and 18K Canopus™ gold, it features an 18K Sedna™ gold bezel and a sun-brushed dial in the same lustrous material treated with black PVD.

Its indexes, polished minute and hour hands are in applied 18K Sedna™ gold. An 18K Sedna™ gold polished seconds hand is set in the tourbillon titanium bridge. The crown, also in polished 18K Sedna™ gold, features a Ω set in 18K Canopus™ gold.

Presented on a black leather strap with polished 18K Sedna™ gold buckle, this exceptional example of the watchmaker's art looks sensational from all angles, as the sapphire crystal caseback allows a view of the 18K Sedna™ gold movement: OMEGA’s Master Co-Axial Chronometer Calibre 2640.

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.

CanopusTM Gold

OMEGA has been using the exclusive Canopus GoldTM, an 18K white gold alloy, since 2015. As well as being 100% noble, it bears all the standard characteristics of other 18K golds, while also distinguishing itself for its high brilliance, whiteness and longevity, making it an ideal material for high-end or diamond set timepieces.
The alloy is named after the bright star Canopus, which is 71 times bigger and 10’000 times brighter than our sun. Due to its brilliance and position, Canopus became an important reference point for many space agencies.
Its unique composition includes platinum, rhodium and palladium for colour and stability.

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.
