Black ceramic on Leather strap
It was the adventures and the accomplishments of the Apollo 8 astronauts that inspired the all-black, ceramic Speedmaster Dark Side of the Moon, but it is the mystique of the Earth’s nightlight and its ever-changing yet constant presence that has spurred the creation of the Speedmaster Dark Side of the Moon "Sedna Black".
This 44.25 mm model has a completely brushed black ceramic case with an 18K Sedna™ gold bezel ring which matches the 18 Sedna™ gold applied indexes and hands. The marks on the matt grey dial have been created using laser ablation.
The "Sedna Black" is presented on a black leather strap with a brushed ceramic foldover clasp. At its heart is the OMEGA Co-Axial calibre 9300.
Label given to a watch which has undergone precision tests and received a certificate from an official body (COSC).

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.

OMEGA has unrivalled expertise in the use of ceramics, dating back more than 10 years. Taking its origin from the Greek word "keramos", ceramic is an inorganic, non-metallic substance obtained by firing at high temperatures. It allows the creation of completely dense watch parts with exceptional mechanical properties. Ceramic is one of the most popular choices for customers when selecting their timepiece, thanks to its appealing colour range and specific properties, such as it being two times lighter than stainless steel, hardwearing, highly scratch-resistant, chemically inert, hypoallergenic, environmentally friendly and non-magnetic.

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.
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.
