Bonhams Offers Rare Richard Mille Rafael Nadal RM27-01 Prototype at Auction

Bonhams to Auction Ultra-Rare Richard Mille Rafael Nadal RM27-01 Prototype

Auction house Bonhams has listed an exceptionally rare Richard Mille RM27-01 ANCA prototype for an upcoming sale. This limited prototype production wristwatch, reference RM27-01 ANCA, is numbered 06 and dates to approximately 2014. The piece represents one of the most coveted iterations of Richard Mille's legendary collaboration with tennis champion Rafael Nadal.

The RM27-01 was conceived as an ultra-lightweight sports watch capable of withstanding the extreme forces generated during professional tennis play. The prototype designation makes this particular example even scarcer than standard production models, which are already produced in extremely limited numbers.

Watch Specifications and Details

Accompaniments and Service History

The lot includes a comprehensive set of accompanying items from the manufacturer:

• Original maker's certificate
• Service watch case
• Service receipt
• Service booklet

According to Bonhams, the watch carries a service warranty valid until March 2026, confirming recent maintenance by an authorized service center. This extended warranty adds significant value for collectors who prioritize authenticated service histories.

The presence of all original documentation and service records makes this a particularly well-preserved example of one of haute horlogerie's most technically advanced timepieces.

The Richard Mille x Rafael Nadal Partnership

The RM27-01 represents a milestone in the ongoing partnership between Swiss watchmaker Richard Mille and Spanish tennis legend Rafael Nadal. Launched around 2014, the model was engineered to endure accelerations of up to 10,000 Gs — forces generated during Nadal's powerful forehand strokes.

The carbon construction and skeletonized movement allow the watch to weigh under 20 grams, including the strap. This extreme lightness is critical for an athlete who demands no compromise between performance and watchmaking excellence. The prototype version adds an additional layer of rarity, as these pre-production pieces were never intended for retail sale.
