Amazon.com Product Description
Set sail with confidence and style to points unknown with this classic mid-sized Omega Aqua Terra stainless steel men's automatic chronometer watch, part of Omega's Seamaster line. As comfortable negotiating deals in the boardroom as it is navigating the breaking seas, this highly accurate timepiece features a slightly raised, highly polished bezel that frames a black dial background with dagger-shaped golden hands (with seconds hand) and stick dial markers in silver tone, small minute indexes, and date display at 3 o'clock. This mid-sized watch measures 36.2mm wide (1.43 inches) and 11.4mm thick (0.45 inches). Other features include a 48-hour power reserve, triple-link stainless steel bracelet band, scratch-resistant and glare-proofed domed sapphire crystal, and water resistance to 150 meters (500 feet)--suitable for swimming, snorkeling, and light recreational ping.
It's powered by Omega's break-through Co-Axial escapement. Developed in conjunction with master watchmaker George Daniels, it's based on double co-axial escape wheel, a lever with three pallet stones and impulse stone on the balance roller, together with a free sprung-balance. The Co-Axial escapement system reduces sliding friction compared with the lever escapement and thus ensures greater accuracy over time.
This watch also features the Omega 2500 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.
The Omega Story

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. Omega watches rocketed off to space on many subsequent missions, including visits to Skylab and the historic Apollo-Soyuz link-up of Soviet and American astronauts in 1975.
In more recent years, Omega created the world's first self-winding wristwatch with central tourbillon in 1994 and made history in 1999 with the first mass-produced watch incorporating the co-axial escapement, developed in conjunction with renowned English master watchmaker George Daniels. In simple terms, the escapement is the heart of a mechanical watch, generating the impulses that make the mechanism move. Omega's Co-Axial Escapement drastically reduces the friction among the parts that transmit energy to the other components, producing greater stability and precision and reducing service requirements.
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.
