The Omega Speedmaster Moon is the iconic chronograph that went to the Moon, a symbol of precision and space exploration.

About this subject

The Omega Speedmaster Moon, known as the Moonwatch, is a manual-winding chronograph that became one of the most famous watches in history. It was qualified by NASA in 1965 for use in manned space missions after rigorous tests of resistance to vibrations, extreme temperatures, and vacuum. The model worn on Apollo 11 in 1969 was the Speedmaster Professional Ref. 105.012, equipped with the caliber 321 (later replaced by the 861 and then the 1861). Buzz Aldrin wore his Speedmaster during the moonwalk, while Neil Armstrong left his in the lunar module as a backup. Since then, the watch has accompanied all Apollo missions and is still used by NASA today.

The design of the Speedmaster Moon is marked by its 42 mm stainless steel case, black dial with tritium-coated markers and hands (later Super-LumiNova), and the black tachymeter bezel. The manual-winding caliber 1861 movement is an evolution of the legendary caliber 861, with a 48-hour power reserve. The case features asymmetrical crown guards and a solid caseback engraved with the Apollo 11 emblem. The five-link stainless steel bracelet is equally iconic.

Beyond its space legacy, the Speedmaster Moon is one of the most collected watches in the world. Omega has released special editions such as the Speedmaster Apollo 11 50th Anniversary, honoring 50 years of the lunar landing, and versions with gold and platinum dials. The association with the moon and space exploration has made the Moonwatch a symbol of adventure and mechanical precision, valued by both astronauts and enthusiasts. Dramatic lighting in photographs of the watch, such as the Rembrandt style, highlights its contours and details, reinforcing its classic and timeless aesthetic.
