Richard Mille: RM 021 Tourbillon wristwatch “Aerodyne”/2009

Orthorhombic titanium aluminides are new group of alloys, developed from the main class of titanium aluminides, which possess a specific crystalline molecular structure ordered on the orthorhombic phase of Ti2AlNb. Its use within a honeycombed geometrical pattern was originally the subject of research by NASA for application as a core material of supersonic aircraft wings, where resistance to extremely high temperatures and torsion is paramount. The alloy in this honeycombed form has unparalleled stiffness, a low thermal expansion coefficient and exceptional torsion resistance.

The actual shape of the baseplate itself as seen from the dial side resembles the trench-like V- shaped profile of a flying wing aircraft where the wing tips are positioned higher than the central body of the aircraft itself. The winding barrel and the tourbillon are both placed in the central depth of this aerodynamic structure, balancing on light and airy bridges with four arms on two sides.

Available in titanium and 18-carat red or white gold, with alligator strap and matching buckle.
