The Omega Speedmaster Calibre 321 Platinum 311.93.42.30.99.001 is one of the most exclusive and historically significant modern interpretations of the legendary Moonwatch. Crafted in solid platinum, this 42mm Speedmaster elevates Omega’s most iconic design into true haute horology territory. At its core is the reborn Omega Calibre 321—faithfully reconstructed using original specifications and modern manufacturing, and famously known as the movement worn on the moon during NASA’s Apollo missions. This manual-wind, column-wheel chronograph represents one of the most revered calibers in watchmaking history, offering both technical pedigree and collector significance. The dial is where this reference truly distinguishes itself. A deep black onyx base provides a striking contrast to the three subdials, each crafted from genuine lunar meteorite—making every example subtly unique. The applied white gold indexes and hands complete the refined, high-contrast aesthetic. The platinum case is complemented by a polished black ceramic bezel with tachymeter scale, staying true to the Speedmaster’s tool-watch heritage while delivering a distinctly luxurious execution. A sapphire crystal protects the dial, while the watch is paired with a premium black leather strap, rounding out its elevated presence. Produced in limited quantities due to the complexity of manufacturing the Calibre 321, this reference is highly sought after and rarely seen on the market. It represents a perfect fusion of Omega’s spacefaring legacy, rare materials, and meticulous craftsmanship. A true collector’s Speedmaster—combining historical significance, mechanical purity, and unmistakable presence.
