Blending classic timepiece design with refined European style, this Omega Constellation men's automatic watch is comfortably at home in both the boardroom as well as the baccarat table. The large, round silver case measures 38mm wide (1.50 inches) and it's topped by a commanding silver bezel with tonal engraved Roman numerals and wide claw accents at 3 and 9 o'clock. It frames a golden dial with polished silver stick hour markers, dagger-style hands (with seconds hand), and a date window at 3 o'clock. Other features include a 48-hour power reserve, scratch-resistant and glare-proofed domed sapphire crystal, and water resistance to 100 meters (330 feet)--offering protection from accidental splashes as well suitable for swimming, snorkeling, and light recreational diving.

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.
