The RM 21-02 Tourbillon Aerodyne represents Richard Mille's uncompromising approach to precision, lightness and structural performance. This edition combines white Quartz TPT with black Carbon TPT and Grade 5 Titanium, creating a distinctive monochromatic contrast while preserving the highly technical character of the Aerodyne collection. At the heart of the watch is the manually wound Calibre RM21-02, featuring a tourbillon, function selector, power-reserve indicator and torque indicator. The open-worked architecture exposes the honeycomb baseplate constructed from HAYNES® 214® alloy with a Carbon TPT core, while the bridges are crafted from Grade 5 Titanium. The tonneau-shaped case measures 42.68 × 50.12 × 14.30 mm and is water resistant to 50 metres. The movement operates at 21,600 vibrations per hour and provides approximately 70 hours of power reserve. The watch is produced as a limited edition of 50 pieces.
