Omega Speedmaster

Omega Speedmaster is a brand of chronograph wristwatches produced by the Omega Watch Company. Many different watches have been marketed under the Speedmaster name over the years. The manual winding Speedmaster Professional or "Moonwatch" is the most well-known and longest-produced; it was worn during the first American spacewalk during Gemini 4 and was the first watch worn on the moon during Apollo 11. The Speedmaster Professional remains one of several watches qualified by NASA for spaceflight and is still the only one so qualified for EVA. The Speedmaster line also includes a multitude of other models, including analog-digital and automatic mechanical watches.
