Handcrafted by a select group of horologists at OMEGA’s Atelier Tourbillon in Switzerland, this Numbered Edition timepiece combines a true example of watchmaking art with the brand’s most advanced and beautiful alloys.

The brushed 43 mm case is made from 18K Canopus Gold™ with a polished bezel, lugs, and caseback, along with a sun-brushed 18K Sedna™ Gold dial that includes a logo and wording in dark grey. The dial is further split between a fluted central ring made from 18K Canopus Gold™ and the outer sections with 18K white gold hour/minute hands and indexes that have all been given a Canopus Gold™ PVD coating.

To enhance the effect, the tourbillon titanium bridge with hand-polished bevelling is set with a diamond-polished 18K Canopus Gold™ seconds hand. On the back, an 18K Sedna™ Gold, PVD-blackened hand indicates the Power Reserve of the watch. The crown, also in polished 18K Canopus Gold™, features a Ω set in 18K Sedna™ Gold.

Presented on a brown leather strap with a polished 18K Canopus Gold™ buckle, the watch includes a sapphire crystal caseback that allows a view of the 18K Sedna™ Gold movement: OMEGA’s Co-Axial Master Chronometer Calibre 2640. Each Tourbillon is delivered in special box with a certificate of authenticity, a travel pouch and a watch crown winder.

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.

Canopus GoldTM

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.
