The De Ville Co-Axial Chronograph uses the OMEGA Co-Axial Escapement in the OMEGA calibre 3313 self-winding chronograph movement. In addition to the proven combination of the escapement with the free sprung-balance, which offers greater regulating stability, the chronograph mechanism is equipped with a column wheel: a ratchet wheel with columns that govern the precision operation of various levers for the chronograph functions. As a prestige movement, the OMEGA calibre 3313 naturally has an exclusive finish with circular graining, Geneva wave decor, rhodium-plated surfaces and gold-plated engravings, as well as a blued-steel centre screw – all visible through the transparent sapphire crystal case back. The movement's precision is attested by its chronometer certificate issued by the official Swiss chronometer testing institute COSC. It has a power reserve of 55 hours.
These models are ideally complemented by a gold or steel bracelet which is made up of rows of 5 individual metal links lengthwise and a butterfly clasp that fits perfectly with the lines of the bracelet and case. Matching hand-sewn alligator leather straps are also available, with an 18-carat gold or stainless steel foldover clasp.
