Blending refined European design with glittery diamond-accented style, this Omega Constellation women's watch offers graceful lines and a slender width for even the more delicate of wrists. Offering an appealing balance of luxury, durability, and precision (with its Swiss quartz watch movement), this Constellation will capture attention immediately as you walk into the ballroom (or boardroom) with its shiny, fully diamond encrusted silver stainless steel bezel. The silky smooth silver stainless steel bracelet band flows seamlessly from the case and is slightly tapered. It's composed of alternating wide links and contrasting thin bands, and is joined by a secure push-button safety clasp. 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.
