OMEGA is proud to include the Swiss Made mark on all of its watches. This simple wording guarantees a standard of quality established over many centuries and is a world-renowned symbol of excellence.

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.

1 / 3

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.
2 / 3

Ceramic

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, and non-magnetic.
3 / 3

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

At the heart of this timepiece is the Co-Axial escapement, a revolution in watchmaking when first introduced. The reduced stress on the moving parts means less need for lubrication, longer-lasting accuracy and a more stable power reserve rate. In short, this timepiece performs better for longer.

1 / 5

Superior Precision

Our Co-Axial movements benefit from the revolutionary Co-Axial escapement within their design. With less friction created, they are able to maintain accuracy over a longer period of time, as well as a more stable power reserve rate. Each movement is Chronometer-certified according to international standard ISO3159, requiring a precision of -4/+6 second per day, following the tests at the Official Swiss Chronometer Control (COSC).
2 / 5

Water-Resistance

To ensure the integrity of our timepieces at depth, not just some but all watches are fully immersed in water and pressure is applied up to the point of the guaranteed water resistance. By submerging each watch in water we have chosen – yet again - to exceed normal testing standards.
3 / 5

5-Year Warranty

In our quest to raise industry standards and push the boundaries of quality, all OMEGA watches are offered with a full 5-year warranty. This customer promise shows the confidence we have in the excellence of our timepieces, and provides extra trust and assurance when choosing your watch.
4 / 5

Less servicing

Expect fewer visits to the service centre. The Co-Axial escapement is designed to reduce friction inside the movement. As a result, less lubrication is needed and hence less servicing. Compared to non-Co-Axial watches, the intervals between getting your watch serviced will be much longer.
5 / 5

Shock-resistance

During the homologation process, OMEGA watches are tested to the extreme. This phase includes shock examinations, to confirm reliability and to check that its precision is maintained after a severe impact. All OMEGA timepieces are designed to withstand shocks corresponding to a 1-metre drop on a hard wooden floor. For a standard 150g timepiece, this sudden and rapid acceleration is an equivalent force of up to 5,000 G on the watch head.

Movement Calibre OMEGA 9300

Self-winding chronograph movement with column wheel mechanism and Co-Axial escapement. Silicon balance-spring on free sprung-balance, 2 barrels mounted in series, automatic winding in both directions. Rhodium plated finish with exclusive Geneva waves in arabesque.
