Description

An extraordinary expression of the art and craft of watchmaking, this incredible timepiece combines classic tourbillon technology with expressive contemporary design.

The newly-designed 44mm tourbillon case is crafted from 18K Sedna™ gold, as are the “flying hands”, which are applied to a sapphire crystal, and the brushed seconds hand that is set within the tourbillon titanium bridge.

The dial and the inner ring are sun-brushed 18K Sedna™ gold treated with blue PVD, while the elegant 18K Sedna™ gold second markers form a ring in a railroad design obtained by laser ablation. The words “Co-Axial Chronometer” and the OMEGA symbol in 18K Sedna™ gold were revealed when the PVD treatment was removed.

Presented on blue leather strap with an 18K Sedna™ gold clasp, the outstanding chronometric performance is achieved through OMEGA’s exclusive calibre 2638.

Finally, the caseback is embossed with a medallion featuring Chronos, the God of time, and with the tourbillon’s own serial number.

1 / 2

Sedna^TM Gold

OMEGA has been using the exclusive 18K Sedna^TM 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, Sedna^TM 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.

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.
