Description

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 worn 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.
