Known for its beautifully intricate design, the original Calibre 321 was the first movement ever used in the Omega Speedmaster in 1957. Most famously, it was used in a variety of space-bound models including those that went to the moon. After extensive research and reconstruction in a dedicated workshop, the Calibre 321 has now been reborn in-line with its original specifications.
To view the reconstructed movement, customers will be able to look through the sapphire-crystal caseback of the new Speedmaster Moonwatch 321 Platinum. As the name suggests, the chronograph features a 42mm brushed and polished case crafted from a special platinum alloy with the use of gold (Pt950Au20). The case design is inspired by the asymmetrical 4th generation Speedmaster case with twisted lugs (ST 105.012), and is presented on a black leather strap with a platinum buckle. Furthermore, this exciting timepiece includes a black ceramic bezel with the Speedmaster’s famous tachymeter scale in white enamel.
Of course, there are plenty of other captivating features to explore too. The step dial is formed from onyx, with a deep black colour that works in perfect harmony with the other materials, including 18K white gold for the indexes and most hands. Another very notable feature is the three meteorite subdials. In tribute to the Speedmaster’s lunar history, OMEGA has used real slices of moon meteorite, providing a genuine link to the Calibre 321, which has powered every Speedmaster ever worn on the moon.
