Crafted from stainless steel and 18 karat yellow gold, this midsize Constellation series watch from Omega is a handsome luxury timepiece for business, dress, or sport occasions. Goldtone hands and hour markers are featured against a white dial, along with a sweep seconds hand and a date display at the three o'clock hour. Set in a round steel case, the dial is capped with a virtually scratch-proof domed sapphire crystal and framed by a solid gold bezel with engraved Roman numerals. This Omega watch is showcased on a steel bracelet with full gold bars between the links. It boasts precise Swiss quartz movement and is rated water resistant to 100 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.
