The De Ville Co-Axial is one of the most prestigious timepiece collections from Omega. These timepieces incorporate Omega’s revolutionary Co-Axial Escapement movement, and available in many versions for both ladies and gents. In 2004, Omega enriched this collection with new gents’ models in 35mm case size.
The Co-Axial Escapement was invented by master British watchmaker George Daniels, who worked together with Omega over a period of five years to develop it for large-scale industrial production. It was one of the twentieth century’s major revolutions in watchmaking – a complete departure from the traditional escapement design. The new design relies on a radial transmission of energy and thus helps to considerably reduce friction in the watch. The result is better long-term accuracy compared with the lever escapement.
A choice of three Omega calibres is available in the standard De Ville Co-Axial collection, each with official COSC chronometer certification: calibre 2500, the standard self-winding version; calibre 2627, with power reserve indicator at 6 o’clock and calibre 2628, with central 24-hour hand. Each of these movements has an exclusive finish of circular graining, Geneva wave decor, polished bevelled bridges, rhodium-plated surfaces and gilt engravings as well as a power reserve of 44 hours.
The 35mm models are available in 18-carat red gold with a white dial or stainless steel with a silver dial. In each case, the dial has the characteristic cambered aspect of all gents’ De Ville Co-Axial models, with applied Omega symbol and name, applied facetted hour markers and luminous, facetted and diamond-polished Alpha hands with blued-steel seconds hand. The polished bezel holds in place a domed scratch-resistant sapphire crystal with multi-layered anti-reflective treatment on the inside, with scratch-resistant sapphire crystal also used for the case back, to reveal the unique Co-Axial movements.
The De Ville Co-Axial Chronograph in 35mm case size shares the same design traits as the Co-Axial chronometers. It is distinguished by its high-end chronograph movement with a 55-hour power reserve. The Omega calibre 3313 self-winding chronograph-chronometer movement has a column-wheel mechanism and has the COSC chronometer certification.
All De Ville Co-Axial models also use the Omega free sprung-balance, which offers better long-term regulating stability in the movement. Each model is available with a matching brickwork-effect bracelet, with rows of five links and a satin-finished central section and polished edges, or a brown alligator leather strap with a foldover clasp. A screw-in case back and double gasket crown ensure water resistance to 100 metres/330 feet for all gents’ De Ville Co-Axial models.
