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 42 mm 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.
