Description

With a complex level of workmanship on the outside, and revolutionary mechanics within, the OMEGA Hour Vision is a watch that is finely balanced in every way.

In this model, the case is made from 18K Sedna™ gold, with a unique two-zone opaline-silver dial that delivers an instant impression of refinement.

The hands and Roman numeral indexes are also made with 18K Sedna™ gold, as is the polished-brushed 9-row bracelet.

Days can be checked by the date window at 3 o'clock, while on the inside, this classically beautiful watch is driven by OMEGA's Co-Axial Master Chronometer Calibre 8901, a state-of-the-art movement that can resist magnetic fields up to 15,000 gauss.

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.

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.

A new look for your watch

Your watch and strap should go together perfectly, but that doesn't mean you can't experiment with different combinations. Why not mix things up and see what happens? You may discover a look that's as individual as you are.

The advantages
of this watch

Inside this timepiece are the revolutionary components that guarantee the highest standards of performance. From the Co-Axial escapement for long-lasting precision, to the silicon balance spring for superior anti-magnetism, OMEGA has conquered every challenge that matters.
