Just as there are very few brands capable of successfully combining High Jewelry with hightech Fine Watchmaking, only a fortunate few will wear the Tourbillon RM 51-02 Diamant Twister. One cannot reduce the supreme sophistication of this Richard Mille limited edition to its 270 diamonds spiraling across the gold dial and titanium bridges, nor to the over 300 operations required to create the typical Richard Mille three-part case, whose rounded shape is accentuated by black sapphires on this model. Welcome to the micromechanical world of cutting, stamping, milling, polishing and satin-brushed, taken to extremes on this classic Richard Mille curving design that is extremely comfortable to wear but very complex to achieve. This pursuit of the exceptional is reflected in the black onyx mainplate visible through the back, which Richard Mille describes as “a stone that embodies balance and inspiration”. It is equally apparent in the manual finishing lavished on the movement, while fans of performance will appreciate the tourbillon, the variable inertia balance wheel, the balance wheel with progressive recoil – as well as the dynamometric crown set with precious stones that can be wound so as to display the maximum power reserve on a rotating disk between 10 and 11 o’clock. With Richard Mille, diamonds are not only forever, but also resolutely avant-garde.
