The Omega Speedmaster Moonwatch, a chronograph approved by NASA, accompanied astronauts on all Apollo missions, including the Moon landing.

About this subject

The Omega Speedmaster Moonwatch is one of the most iconic watches in history, famous for its role in NASA's space missions. Introduced in 1957, it was designed as a robust chronograph for professional use. In 1965, after rigorous testing, NASA certified it as official equipment for manned space flights, outperforming competitors like Rolex and Longines.

During the Apollo program, the Speedmaster was worn by astronauts on all missions, including Apollo 11, when Buzz Aldrin wore his watch on the Moon. Although Neil Armstrong left his in the lunar module, the Speedmaster became known as the Moonwatch. During Apollo 13, the chronograph was crucial for timing propulsion burns during the return to Earth after the onboard explosion.

The manual-winding caliber 1861 (previously 861) is renowned for its reliability and tradition. The design includes a black dial, coffin-shaped hour and minute hands, and a tachymetric scale. The 42 mm case maintains the original proportions. The current version, reference 311.30.42.30.01.005, stays true to the historical model, with improvements such as a sapphire crystal and upgraded movement.

Culturally, the Speedmaster transcends the watch world. It symbolizes space exploration and Swiss precision engineering. It is one of the most collected watches, with special editions like the Snoopy Award. Its history is constantly celebrated, keeping the legacy alive among enthusiasts and new admirers.

Frequently Asked Questions

Why was the Omega Speedmaster chosen by NASA?

NASA conducted rigorous tests in 1965 on several chronographs, evaluating precision, shock resistance, temperature variations, and acceleration. The Speedmaster was the only one to pass all tests, earning its certification for space flights.

Is the Speedmaster Moonwatch still produced today?

Yes, Omega continues to manufacture the Speedmaster Moonwatch. The current model (reference 311.30.42.30.01.005) retains the classic design with modern improvements, such as a Co-Axial movement and sapphire crystal.
