This Royal Oak Frosted Gold Double Balance Wheel Openworked is designed in a 41mm frosted 18-carat white gold case. This method is achieved by the Florentine Technique which involves a diamond-tipped, needle-like tool that hammers into the surface of the gold, creating tiny facets. This allows for an almost diamond-like appearance that shimmers and is rough to the touch. It features an open-worked grey dial, a double balance wheel visible on both sides of the watch, glareproof sapphire-crystal and caseback with screw-locked crown. It comes on a 18-carat white gold bracelet with AP folding clasp.
