Introducing Horological Machine N°4 in an envelope of red gold, titanium and sapphire. Beneath the aerodynamic shell are two barrels, connected in parallel and which transfer power to the two identical, turbine-shaped indication pods. In the central cockpit, the streamlined cock has been cut away in its middle to reveal as much of the oscillating wheel as possible, and the sophisticated finish of these micromechanics. This three-dimensional aesthetic was conceived specifically to house the engine, whose 311 components are all tailor-made.
