About this subject

The Omega Speedmaster Moon, officially known as the Omega Speedmaster Professional, is a mechanical chronograph that gained worldwide fame after being selected by NASA for space missions. In 1965, after rigorous tests for resistance to vibrations, extreme temperatures, and vacuum, the Speedmaster was certified for manned flights. It was worn by Buzz Aldrin during the first lunar landing on July 20, 1969, becoming the first watch on the Moon. Since then, it has accompanied all Apollo missions, including Apollo 13, where it was crucial for timing engine burns during the return to Earth.

The design of the Speedmaster Moon features a black dial with subdials for the chronograph, a tachymeter bezel, and a stainless steel bracelet. Its manual-wind movement, caliber 1861 (heir to caliber 861), is renowned for reliability and accuracy. The 42mm case has characteristic crown guards and a hesalite crystal, which better withstands pressure changes than sapphire. Some recent versions have a transparent case back to view the movement.

The cultural significance of the Speedmaster extends beyond space exploration. It has become a symbol of precision, adventure, and endurance. Celebrities, astronauts, and enthusiasts wear it as an icon of style. The Moonwatch, as it is popularly called, retains vintage features that evoke the space era, while special editions, such as the 50th anniversary of the lunar landing, celebrate its legacy. The watch has been in continuous production since 1957, with minor aesthetic and technical updates, but preserving the essence that makes it so coveted.
