Inspired by the tourbillon watches of the RM 027 collection that Rafa Nadal wears on the tennis court, the new Richard Mille RM 035 ‘Baby Nadal’ collection is designed as a condensate of technology for anyone in thrall to performance. The new RM 35-03 Automatic Rafael Nadal, the fourth timepiece in the collection is fully worthy of its place in this distinguished lineup, to which it brings a patented innovation, namely the butterfly rotor.

Following three full years of development, Richard Mille has presents this new system for movement winding which spreads its wings like a butterfly in the RM 35-03. While the Calibre RMAL1 of the RM 35-02 already possessed a variable geometry rotor—a signature component of Richard Mille automatic movements—the new butterfly rotor of the RM 35-03 allows the wearer to directly interact with the rotor’s geometry, controlling the movement’s winding speed based on lifestyle and activity levels, for a complication that is playful and practical in equal measure.

The butterfly rotor consists of two grade 5 titanium arms mounted with heavy metal weight segments, activated by a separate gear train via a dedicated push piece. In their initial position, the weight segments create a radial displacement of the gravitational center outward, converting the wearer’s every movement into the torque needed to rewind the barrel.

In shifting between modes —from the normal mode that winds the barrel spring to the ‘sports mode’ that suspends the rotor’s activity— pressure on the push-piece prompts the function to deliver haptic feedback, allowing the wearer to actually feel the weight segments springing apart on their wrist. A winding indicator at 6 o’clock on the dial, shows whether the oscillating weight is active —ON or not OFF. Rounding off the movement commands is a function selector.

At a press of the push-piece at 2 o’clock, the user may shift between winding ‘W’, neutral ‘N’, and time-setting ‘H’ activities. Press the push-piece at 7 o’clock, however, and the rotor’s gears spread the two weights to a 180° angle. The gravitational center is aligned and the rotor returns to a balanced position, suspending the winding process and thereby preventing excessive winding of the movement.

“Previously, any modification of the rotor’s geometry needed to be done by one of our licensed watchmakers. We wanted to perfect this system and give wearers the possibility of directly acting on the watch’s winding speed. It’s like a driver being able to adjust the transmission style from city use to racetrack by activating the sports mode” explains Salvador Arbona, Technical Director for Movements.

Graceful and ergonomic in its lines, the RM 35-03 is available in two versions —blue Quartz TPT with a white Quartz TPT caseband and white Quartz TPT and Carbon TPT with a Carbon TPT caseband.

Entirely skeletonized, the movement can be admired from both sides thanks to sapphire crystals on the front and back. The baseplate and bridges, crafted of grade 5 titanium with a grey electro plasma and PVD treatment, further accentuate the bold visual statement of this watch. 

'“In our respective domains, we both seek to achieve excellence. We speak the same language, Richard and I. We’re both passionate about our work. Keeping alive this flame of passion for what we do each day is essential to me. Even though I don’t wear the RM 035 models in competition, it is heart-warming to feel the confidence that he and the teams show in allowing me to participate in this singular adventure.” —Rafa Nadal
