Omega Speedmaster Calibre 321 39 mm Stainless Steel with Black Dial

The Speedmaster Calibre 321 39 mm Stainless Steel is one of the most revered recreations in modern Omega history, meticulously crafted to honor the exact Speedmaster reference worn during the earliest manned space missions. Faithful to the 1957–1965 lineage, this model blends authentic vintage proportions with contemporary precision, making it a grail-level piece for collectors.

Its 39 mm stainless-steel case follows the classical straight-lug design of the original pre-Professional Speedmasters, paired with a step black dial, applied Omega logo, and period-correct chronograph subdials. Every detail — from the dot-over-90 (DON) tachymeter bezel to the hesalite-style crystal profile — has been executed with meticulous respect for historical accuracy.

Inside beats the legendary Calibre 321, the hand-assembled movement that powered Speedmasters worn during the Gemini and Apollo programs. Recreated using original specifications and assembled by a dedicated team of specialists, the Calibre 321 represents one of the rarest and most celebrated movements in Swiss watchmaking.

Finished with a classic stainless-steel bracelet, this reference captures the spirit of NASA’s golden era while offering refined modern craftsmanship. It is a timeless, museum-grade chronograph built for collectors who appreciate the true heritage of the Moonwatch.
