The Speedmaster Moonwatch 321 Stainless Steel is the latest step in the historic decision took by OMEGA in early 2019 by recreating its iconic Calibre 321. In July 2019, the Swiss watchmaker unveiled the first new timepiece to house the movement – a Moonwatch in platinum.

In 1965, when astronaut Edward White became the first American to walk in space he was wearing the Speedmaster ST 105.003. OMEGA’s latest offering takes inspiration from that famous model.

The 39.70 mm case in stainless steel, influenced by the same 3rd generation style that Ed White wore, features a bezel ring in polished black ceramic [ZrO2] with a tachymeter scale in white enamel. Gracing the black step dial are the familiar Moonwatch hands, small seconds sub-dial, 30-minute recorder and 12-hour recorder, and central chronograph hand.

This timepiece proudly highlights the iconic “Dot over Ninety” and other respectful nods to the past, including vintage OMEGA logos throughout the design.

Known for its beautifully intricate design, the original Calibre 321 was the first movement ever used in the OMEGA Speedmaster in 1957.

As well as powering Ed White’s spacewalk Speedmaster referenced above, the famous movement drove the Speedmaster ST 105.012, better known as the first watch worn on the Moon. The owners can admire the iconic Calibre through the sapphire crystal caseback.

After extensive research and reconstruction in a dedicated workshop, the Calibre 321 was recreated in-line with its original specifications, and released in time for the 50th anniversary of the first lunar landing.
