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 easily readable dial including Arabic numerals at the quarter hours, triangular hour markers, and small minute indexes. This round watch measures 39.2mm wide (1.54 inches) and 11.6mm thick (0.46 inches). Other features include a 44-hour power reserve, supple brown leather strap with white contrast stitching, scratch-resistant and glare-proofed domed sapphire crystal, and water resistance to 150 meters (500 feet)--suitable for swimming, snorkeling, and light recreational diving. This watch also features the Omega 2403 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.
