The Omega Speedmaster “Apollo XI” 25th Anniversary, ref. ST 3591.50.00, is a commemorative chronograph introduced in 1994 to mark a quarter-century since the 1969 Apollo 11 moon landing. Limited to 2,500 pieces, this stainless-steel Speedmaster retains the classic 42 mm Moonwatch proportions, with a black dial, black aluminium tachymeter bezel, and the traditional three-register layout. The case side is engraved with “Apollo XI 1969-1994”, underlining its heritage significance. Inside, it is powered by the hand-wound Calibre 861, a reliable and historically important movement. This edition offers collectors a meaningful link to Omega’s space legacy, wrapped in a subtly modified yet faithful Moonwatch design.
