The RM 21-02 Tourbillon Aerodyne has set the highest limits for watchmaking both in terms of its design, mechanical inventiveness and use of materials.
Richard Mille has always capitalized on engineering materials from fields way beyond watchmaking. These new and technical materials are recognized today in Haute Horlogerie for their aesthetic and their mechanical properties.
Richard Mille were intent on achieving extreme lightness on the RM 21-02 and they succeeded in constructing it on a honeycomb structure. The objective was to juxtapose and laser-weld each tiny cell. This achievement on such a microscopic scale is a major technical tour-de-force.

HAYNES® 214® is a nickel-chromium-aluminium-iron alloy, designed to provide the optimum in high-temperature oxidation resistance for a wrought austenitic material, while at the same time allowing conventional forming and joining. Intended principally for use at temperatures of 955°C and above, 214® alloy exhibits resistance to oxidation that far exceeds that of virtually all conventional heat-resistant wrought alloys at these temperatures.
Combined with a Carbon TPT® core, the honeycombed geometrical pattern of HAYNES® 214® offers unparalleled stiffness, a low thermal expansion coefficient and exceptional torsion resistance.
