Add a true classic to your timepiece collection with the amazingly precise and rugged Omega Speedmaster day-and-date men's watch (model 3222.80.00), the latest generation that first started with the timepiece designed for NASA in the 1960s. It features the Omega 3606 caliber automatic movement, which has been certified as a chronometer by the COSC (Swiss Official Chronometer Control). Only 3 percent of watches produced in Switzerland are "chronometer-certified." To achieve this highly coveted certification, the movements are subjected to numerous tests over a period of 15 consecutive days and nights, in five positions and at three different temperatures. But Omega is more than just a fashionable watch. In 1965, the Omega Speedmaster chronograph was "flight-qualified by NASA for all manned space missions" as the only wristwatch to have withstood all of the U.S. space agency's severe tests, including passing grades for extreme shocks, vibrations, and temperatures ranging from -18 to +93 degrees Celsius. The greatest moment in the Speedmaster's history was undoubtedly 20 July 1969 at 02:56 GMT, when it recorded man's first steps on the Moon's surface as part of the Apollo 11 mission. Today, Omega is known for its rigorous testing of new movements, cases, and bands. Each new Omega movement is tested on the wrist in existing Omega models, while various laboratory tests are conducted to determine temperature-resistance, shock-resistance and vibration-resistance.
