Add a handsome finishing touch to your dress or casual wardrobe with the men's Constellation 1502.40.00 from Omega. Crafted from high-performance stainless steel, it places a brushed steel case on a sleek horizontal link bracelet with polished bar accents. Featured beneath an anti-reflective sapphire crystal, the grey dial offers three-hand function with luminous silvertone Dauphine hands, luminous markers, applied silvertone indices, and a date display at the three o'clock position. The dial is framed by a round steel bezel with polished accents and engraved Roman numerals in black. This Omega watch boasts Swiss automatic movement and is rated water resistant to 50 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.
