Created to celebrate man's first steps on the moon 50 years ago, the 321 Platinum is a highly special Moonwatch. It's powered by a recreation of the Calibre 321 movement — the same one found in every Speedmaster ever worn on the moon. Its 43mm brushed and polished case is made from a special platinum alloy and is inspired by the 4th generation Speedy with twisted lugs. The onyx step dial is complemented by a black ceramic bezel with white enamel tach scale, white gold hands and indexes, and subdials made using real slices of moon meteorite. It's finished with a black leather strap with a platinum buckle and will be available this winter.
