Omega Speedmaster Heritage Models Calibre 321

The Omega Speedmaster Calibre 321 is a faithful rebirth of one of the most iconic chronographs in horological history. Revered as the movement that accompanied NASA astronauts on their pioneering space missions, the legendary Calibre 321 is celebrated for its beauty, reliability, and role in the Moonwatch legacy.

Housed in a polished 39.7 mm case inspired by the 3rd generation Speedmaster worn during the Apollo era, this timepiece unites vintage design with modern craftsmanship. Its stepped black dial, applied Omega logo, and classic chronograph layout evoke the timeless style of the 1960s.

At its heart beats the meticulously reconstructed Calibre 321, recreated by Omega using original specifications and advanced digital scanning of Gene Cernan’s Apollo 17 Speedmaster. The result is a movement crafted with unparalleled authenticity, visible through the sapphire crystal case back.

With its stainless steel case, tachymeter bezel in black ceramic with white enamel scale, and a robust stainless steel bracelet, the Speedmaster Calibre 321 is a true collector’s masterpiece — blending history, precision, and space heritage.
