The calibre 321 is a legendary movement for Omega enthusiasts! Used from 1949 to 1968, its longevity is remarkable, thanks to its sturdiness and good design with the introduction of the column wheel. In fact, it equipped the Speedmasters on the Apollo 11 mission in 1969! As this caliber is an important part of the brand, Omega has decided to reissue it in 2019 after two years of research and development. Proof that this movement is a key piece in the history of the Manufacture.
