RM 27-05 Tourbillon Volant Rafael Nadal

The RM 27-05 Flying Tourbillon Rafael Nadal project may have launched in 2019, but its story is rooted much earlier. This watch is the fruit of a meeting that has since grown into a true friendship. Since then, Rafa has seized one victory after another with Mille watches on his wrist.

The RM 27-05 project was driven by an unwavering quest to eliminate weight and the result boasts an impressive technical data sheet. The movement has a power reserve of 55 hours and incorporates a flying tourbillon that oscillates at a frequency of 3 Hz. Its PVD-treated titanium baseplate is optimally skeletonised and hand-finished, even the hidden parts. The bridges are also made of grade 5 titanium and Carbon TPT® to make them even lighter. The calibre measures 3.75 mm thick and weighs just 3.79 grams.

4,000 hours of work went into designing the calibre and case. We certainly didn’t stint on time when creating the RM 27-05 Flying Tourbillon Rafael Nadal. While its sobriety does mark a return to the collection’s roots, rethinking the watchmaking process has been a leitmotiv at every stage of its development. Here, there are no screws holding the movement to the case. The entire mechanism rests inside the monobloc back/caseband unit, which is then topped by the flange and bezel. The whole assembly presses down on the calibre to hold it firmly in place. What gives this model a major advantage are the qualities of a new composite, Carbon TPT® B.4, developed over the course of five years with our Swiss partner North Thin Ply Technology (NTPT™). Carbon TPT® B.4 is an optimised anisotropic material that makes it possible to machine the case to ever thinner cross-sections. Compared with earlier Carbon TPT®, the new composite is 4% denser, the fibre 15% stiffer and the resin 30% stronger.

For optimum strength, Carbon TPT® B.4 is woven in stacks using a specific 70° orientation between layers. Choosing this material guarantees the watch’s powerful architecture the best ratios, weight, performance and rigidity. It’s what makes it possible to follow the weave of the Carbon TPT® B.4, creating an X-shaped ridge on the caseback that the movement rests on. Comprehensive simulations of the whole, including the case, resulted the calibre being positioned 5/100ths of a mm from the caseback on 6 support points, which contribute to the watch’s stiffness. This X pattern is visually reflected throughout the case, while guaranteeing the bezel, flange and monobloc caseback retain their properties regardless of circumstances.

Thanks to bold and exclusive innovations, every gram removed to complete the RM 27-05 Flying Tourbillon Rafael Nadal adds value to this unparalleled watch. The weight of time takes on a new dimension.
