Omega speedmaster moon

The Omega Speedmaster Moonwatch, NASA's iconic chronograph, was the first watch worn on the Moon and maintains a legacy of precision and durability.

About this subject

The Omega Speedmaster Moonwatch is a mechanical chronograph that gained worldwide fame for its role in NASA's Apollo program. In 1965, after rigorous testing for shock, temperature, and vibration resistance, it was certified for all manned space missions. It was on the wrist of astronauts during the historic Apollo 11 mission in July 1969 when Buzz Aldrin stepped onto the lunar surface. Since then, the model has been known as the Moonwatch.

The movement used is the manual-winding caliber 1861 (and later versions), derived from the Caliber 321, with a 48-hour power reserve. The stainless steel case of 42 mm features hesalite (acrylic) crystal in the classic version, resistant to impacts with a characteristic slight distortion. The black dial with subdials and tachymeter scale is a functional design that has changed little since the 1960s.

Beyond the lunar feat, the Speedmaster accompanied all Apollo missions, including the dramatic Apollo 13, where it was used to time the 14-second engine burn for trajectory correction, saving the crew. It also served on Skylab missions and the Space Shuttle program. Omega has produced special commemorative editions, such as the Speedmaster Professional and the Speedmaster Apollo 11 50th Anniversary, with gold details or exclusive dials. The durability and precision of the Speedmaster have made it not only an icon of space exploration but also a collector's item and a symbol of Swiss engineering.

In the collector's world, the Speedmaster Moonwatch is highly valued, especially vintage versions with the Caliber 321 movement. Authenticity can be verified by serial numbers and details like the Omega logo and the inscription “Professional”. The watch is often used both as a daily wear piece and as an investment item, given its rich history and limited production of certain editions. Regular maintenance is essential to preserve its manual movement, requiring specialized knowledge.
