The flying tourbillon is cantilevered and thus held only at the underside. The whole mechanism, which consists of 73 parts, measures 12.42 millimetres in diameter and 3.85 in height. The lightweight titanium cage, placed on a lubricant-free ceramic ball bearing, is reduced to its bare essence and the 10-millimeter diameter balance wheel is fitted with four regulating screws, ten weight screws and a balance spring with Breguet over coil beating at 4 Hertz.
