Omega speedmaster moon

The Omega Speedmaster Moonwatch is the watch that accompanied Apollo 11 astronauts to the Moon, an icon of space timekeeping.

About this subject

The Omega Speedmaster Moonwatch, first released in 1957, achieved legendary status when it became the first watch worn on the Moon during Apollo 11 in 1969. Chosen by NASA after rigorous testing in 1965, it was standard equipment for all manned missions, including Apollo 13, where it was vital for timing the return maneuvers. Its manual-wind movement, originally the Caliber 321 (later replaced by 861 and 1861), is renowned for its robustness and precision. The black dial with subdials and tachymeter bezel is an iconic design. The classic version features a 42 mm case, hesalite crystal (more impact-resistant), and solid caseback. While modern models use the Caliber 3861 with Co-Axial escapement, the aesthetics remain faithful to the original lunar watch.
