The Omega Speedmaster Professional is more than just a chronograph; it is a cornerstone of horological history and a symbol of human achievement. Globally revered as the "Moonwatch," it holds the unparalleled distinction of being the first watch worn on the lunar surface during the Apollo 11 mission in 1969. This reference, the 310.30.42.50.01.001, represents the most significant evolution of the Speedmaster in decades, meticulously balancing its legendary heritage with Omega's most advanced mechanical engineering.
For collectors and purists, this specific configuration—featuring the traditional Hesalite crystal and a solid caseback—is considered the quintessential Speedmaster. It remains the closest spiritual and aesthetic descendant of the ST 105.012, the very reference certified by NASA for all manned space missions.
