Having been a part of all six lunar missions, the legendary OMEGA Speedmaster is one of the world_s most iconic timepieces. This model has reprised the famous Calibre 321, which was an important part of the Speedmaster_s original space history.
The 39.70 mm case is in stainless steel and is inspired by the same 3rd generation style that astronaut Ed White wore during America_s first spacewalk in 1965. There is also a bezel ring in polished black ceramic [ZrO2] with the tachymeter scale in white enamel.
The black step dial features familiar Moonwatch hands, a vintage OMEGA logo, as well as a small seconds sub-dial, 30-minute recorder and 12-hour recorder along with a central chronograph hand. Through the sapphire-crystal caseback, you can see the Calibre 321 inside.
