About this subject

The Omega Speedmaster Moonwatch, officially known as the Omega Speedmaster Professional, is one of the most legendary timepieces in horology. Launched in 1957, it was initially designed for auto racing but gained worldwide fame when NASA selected it for manned space flights. In 1965, after rigorous tests against extreme temperatures, vibrations, vacuum, and acceleration, the Speedmaster was certified for all agency space missions.

The defining moment came on July 20, 1969, when Buzz Aldrin wore his Speedmaster during the Apollo 11 mission, making it the first watch worn on the Moon. The specific model used was reference 105.012, with a stainless steel case and manual-wind caliber 861. The Speedmaster is known for its minimalist design: a black dial with contrasting sub-dials and a rotating bezel with tachymeter scale, features that have remained virtually unchanged for decades.

Beyond the lunar feat, the Speedmaster accompanied all subsequent Apollo missions and played a role in the Apollo 13 rescue. In 1970, during that mission, the Speedmaster was crucial for timing the 14-second manual engine burn that brought the crew back to Earth. For this contribution, Omega received the Silver Snoopy Award. To this day, the Speedmaster is the only watch qualified by NASA for extravehicular activity (EVA), and it has been in continuous production since its launch.

The manual mechanical movement is a hallmark of the Speedmaster in an era dominated by automatics. The current caliber 1861 is an evolution of the 861, offering precision and reliability. The modern model preserves the original spirit with a hesalite (acrylic) crystal and solid case back, though sapphire crystal versions also exist. The Speedmaster Moonwatch is more than a watch: it is a symbol of adventure, innovation, and endurance, coveted by collectors and enthusiasts worldwide.
