The newest evolution of Omega's highly regarded SeaMaster series, the Aqua Terra delivers bold sporty styling and superior performance, on land or at sea. This model, sized for women, features a highly legible silver dial with luminous hands and markers, a luminous sweep seconds hand and seconds indexes, and a date display at the three o'clock position. The dial is set in a round brushed steel case and capped with a scratch-resistant sapphire crystal. An attractive and durable steel link bracelet completes the look. Other notable features of this Omega watch include Swiss quartz precision and water resistance to a full 150 meters. 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.
