The OMEGA Speedmaster is one of world’s most iconic timepieces. Having been a part of all six lunar missions, the legendary chronograph is an impressive representation of the brand’s adventurous pioneering spirit.

Presented on a black leather strap, this platinum model houses the iconic OMEGA Calibre 321, a movement that has been reborn for today using original specifications. Wearers can view the calibre through the sapphire-crystal caseback of the 42 mm timepiece, which has been crafted from a special platinum alloy with the use of gold (Pt950Au20).

The design also includes a black ceramic bezel with a white enamel tachymeter scale. Most notable is the step dial in black onyx, which uses 18K white gold for the indexes, and most hands. The vintage OMEGA logo is in 18K white gold. The design is completed by three unique subdials formed from a lunar meteorite, the same used for the Speedmaster Apollo 11 50th Anniversary Limited Edition in Moonshine™ Gold.

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.
