Designed as a replica rm-27-03 tourbillon built for the wrist of tennis legend Rafael Nadal, the RM 27-03 is one of the lightest tourbillon watches ever produced. The original weighed under 20 grams including the strap, and this version captures that featherweight concept through a skeletonized movement plate and an NTPT carbon case. Red accents run across the strap and dial perimeter, tying the piece to Nadal’s visual identity on court. At roughly 47.77mm by 38.43mm, the Richard Mille tonneau sits surprisingly flat on the wrist, and transparent sapphire crystals front and back expose the tourbillon cage in full.

Case & Movement Specs

• Case material: NTPT carbon fiber composite
• Case dimensions: approximately 47.77 x 38.43mm
• Crystal: sapphire front and back
• Dial: skeletonized with red accents
• Strap: red rubber with deployant clasp
• Movement: manual-winding tourbillon
• Functions: hours, minutes, tourbillon

NTPT carbon is layered at 45-degree angles before curing under heat and pressure. The result is a pattern of irregular striations unique to every case produced. Red-thread accents embedded in the carbon further differentiate this version from earlier RM 027 references.

Caliber Breakdown

The tourbillon mechanism sits at six o’clock, rotating once per minute inside a cage machined from grade-5 titanium. Manual winding was chosen to keep the movement thin and light, since an automatic rotor would add both thickness and grams contradicting the ultra-light philosophy. The baseplate uses a unibody design inspired by suspension cables. For a broader look at RM tourbillon references, the RM-027 collection shows every variant. Compare the construction against the RM 27-02 with orange fiber case, which uses a different carbon layup.

How It Compares

Among Nadal-signature references, the 27-03 represents the third generation of an ongoing collaboration that started in 2010. Each revision pushed weight lower and shock resistance higher. The red strap makes it one of the more recognizable configurations. This replica rm-27-03 tourbillon in red offers the most direct visual link to match-day appearances.
