Back in the 1960s, NASA had a problem: To keep track of time while bagging moon rocks, astronauts needed a wristwatch with otherworldly ruggedness. Many high-grade chronographs were auditioned. One lost its crystal under extreme decompression; the hands on another warped in the test oven. But the Omega Speedmaster—and its particularly robust movement—had the right stuff. The watch has since been strapped to every astronaut's wrist from Gemini and Apollo to Skylab and the shuttle. Its movement, now known as the Calibre 1861, has seen a few changes over the years to improve its precision, but it's been requalified by NASA for each new mission, and it remains the most strenuously tested movement in history. It's even performed a few tasks those neurotic engineers couldn't have foreseen: After shutting down their computers to save power, the troubled Apollo 13 crew navigated back to Earth using their hand-wound Speedmasters.
Explanation:
Omega Speedmaster is a line of chronograph wristwatches produced by Omega SA. While chronographs have been around since the late 1800s, Omega first introduced this line of chronographs in 1957. Since then, many different chronograph movements have been marketed under the Speedmaster name. The manual winding Speedmaster Professional or "Moonwatch" is the best-known and longest-produced; it was worn during the first American spacewalk as part of NASA's Gemini 4 mission and was the first watch worn by an astronaut walking on the Moon during the Apollo 11 mission.[1][2] The Speedmaster Professional remains one of several watches qualified by NASA for spaceflight and is still the only one so qualified for EVA.[3] The Speedmaster line also includes other models, including analog-digital and automatic mechanical watches.[4
