Richard Mille introduces the RM 64-01 Tourbillon Colnago, a 50-piece limited edition born from the brand’s long affinity with professional cycling. The collaboration with Colnago, the storied Italian frame builder, channels that connection into a movement and case built around the same principles that govern a racing bike: lightness, transparency, and volume. The skeletonized grade 5 titanium baseplate and bridges expose all 274 components of the RM64-01 caliber, with a fast-rotating barrel at 1 o’clock sitting in direct symmetry with the variable-inertia tourbillon at 7 o’clock, a layout that recalls a drivetrain at a glance.

The bridges, lacquered white and hand-painted in azure blue and 5N red gold, take their star-shaped geometry from the Colnago “Master” frames of the 1980s, engineered then to add torsional rigidity without extra weight. That same engineering logic carries into the finishing, where microblasted titanium hub caps in blue lacquer tie the architecture together visually. The color palette borrows directly from the Colnago “C68,” and 5N red gold appears for the first time in a Richard Mille sports watch, extending across the crown cap’s lacquered Ace of Clubs and into hands shaped to echo a bicycle crank.

Lightness remains the governing constraint throughout. The 43.21 by 49.94 by 14.23mm case is built from White Quartz TPT, with notched bezels in a newly developed Azure Blue Quartz TPT created specifically for this reference. Between the tubular case architecture, the frame-inspired bridge geometry, and the cycling-coded color story, the RM 64-01 Tourbillon Colnago reads as a genuine mechanical translation of what makes a racing bicycle work.
