The RM61-01 Yohan Blake is built around an asymmetrical case measuring 50.2 mm × 42.7 mm, a form Richard Mille's engineers developed with aerodynamics as a central goal. The bezel and caseback are fashioned from black TPZ ceramic, a material chosen for its low density and durability, while the mid-section is constructed from NTPT carbon — produced by subjecting ultra-fine carbon fiber to high pressure — resulting in a visually distinctive texture unique to each piece. Case components are fastened with titanium screws, a hallmark detail across the Richard Mille lineup.
Double AR-coated sapphire crystals on both the dial side and caseback provide an unobstructed view of the skeletonized Caliber RMUL2 within, while also offering water resistance to 50 meters. The winding crown features a black rubber O-ring for grip and is flanked by a pair of triangular crown guards. The hand-wound movement runs twin barrels capable of delivering up to 55 hours of power reserve when fully wound.
The watch is worn on a black rubber strap secured by a titanium folding clasp bearing the Richard Mille signature. This edition is limited to 150 pieces worldwide.
