Speedmaster

The Speedmaster is a line of chronograph wristwatches produced by Omega SA. Introduced in 1957 as a sports chronograph for racing and aviation, the Speedmaster is defined by its tachymeter scale on the bezel and its three-subdial configuration. The stainless steel case is typically about 42 mm and the design emphasizes legibility and durability, with a long history of use in demanding environments.

In 1965 NASA selected the Speedmaster for all manned spaceflight missions after rigorous testing, and it gained iconic status as the Moonwatch after being worn during the Apollo program, including the first lunar landing. The Speedmaster’s association with space exploration contributed to its enduring reputation and continued production in multiple variants.

Movements in the line have evolved from the hand-wound Calibre 321 to the Calibre 861, then 1861, and most recently Calibre 3861, which is Master Chronometer certified. The classic Moonwatch remains a manual-wind model, while other Speedmaster lines include automatic versions such as Speedmaster Reduced, as well as special editions with sapphire crystals, ceramic cases, and additional complications like moonphase or racing dials.

Today the Speedmaster encompasses a wide range of models, from faithful reissues of the original Professional to contemporary configurations that blend modern materials with traditional aesthetics. It is regarded as one of the most enduring and recognizable chronographs in horology, with a strong appeal to collectors and enthusiasts alike.
