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.
