Grey Side of the Moon

Speedmaster Dark Side of the Moon 44.25 mm, grey ceramic on leather strap

Sorry, but this watch is no longer available.

OMEGA’s Speedmaster Grey Side of the Moon is an innovative addition to the Speedmaster collection. With its grey ceramic case, sand-blasted platinum 950 dial, Moonwatch-style hands, ceramic bezel and tachymetric scale in white Super-LumiNova, this timepiece is not only ready for adventure but is stylish beyond compare.

Reminiscent of its legendary predecessors, the Speedmaster Grey Side of the Moon has a 60-minute and 12-hour recorder at 3 o’clock and a small seconds sub-dial at 9 o’clock. OMEGA’s Co-Axial calibre 9300 can be seen through the bevelled sapphire crystal caseback.

Key materials

Sapphire Crystal

1 / 3

Platinum

Platinum stands out in the luxury world for its rarity, enduring silvery whiteness and brilliant shine. It is also highly unreactive and has a remarkable resistance to corrosion. The rarity of the material is often associated with exclusivity and wealth, which is why OMEGA uses 950 platinum for exceptional models of prestige. These watches offer wearers a distinctive look and a unique feel unlike any other metal.
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.
