The Richard Mille RM 27 | family history
The RM 27-04 was tested to 12,000g of shock resistance. That figure reflects a genuine engineering brief: Rafael Nadal wears Richard Mille during his matches, and his forehand generates forces that would destroy conventional watch movements. The RM 27 is sports engineering applied to fine watchmaking, and the price reflects one-of-many collector positioning.
Designed for Rafael Nadal's tennis court: the RM 27 series uses tourbillons engineered to survive 10,000g of shock from a tennis swing.
2013-present · The RM 27 and Rafael Nadal
Richard Mille and Rafael Nadal launched their partnership in 2008 with the RM 027 (first Nadal tourbillon) and have produced successive generations tested to increasingly extreme shock tolerances. The RM 27-04 (announced 2022) was tested to 12,000g in a titanium and NTPT carbon case weighing approximately 20 grams. The tourbillon movement is suspended within the case via a cable and pulley architecture that distributes and absorbs impact forces rather than transmitting them to the movement directly. Nadal wore versions of this watch on court during Grand Slam finals, which is both marketing and genuine product proof.
How to read this family
Two honest questions for RM 27 buyers:
- Is the 12,000g shock claim meaningful for a collector wearing this watch normally? No. The 12,000g testing is relevant to Nadal's on-court use; a collector's wrist does not generate anything approaching those forces. What the shock engineering does deliver is a very stiff, very well-regulated movement architecture that performs accurately under the normal shocks of daily wear. The tourbillon in the RM 27 is built to a different specification than a dress-watch tourbillon. You are paying for that engineering whether or not you play professional tennis.
- How does the RM 27 compare to other tourbillons at its price point? The RM 27 trades well into six figures. At that price, buyers can access tourbillons from Patek Philippe, A. Lange and Sohne, and Breguet, each with different movement finishing traditions. The RM 27 differentiates on materials engineering and shock architecture rather than classical decorative finishing. These are genuinely different propositions; which is more interesting depends on what you value in horology.

Which ref to buy
The RM 27 is Richard Mille's collaboration with Rafael Nadal -- an ultra-light tourbillon designed to survive the g-forces of professional tennis. The RM 27-04 weighs approximately 30 grams total and can withstand 12,000 g of acceleration. Extraordinary engineering claim with documented testing.
- 1Openr-rm-27-04Consider
RM 27-04 -- ultra-light tourbillon engineered for 12,000 g shock resistance, the most technically specific Richard Mille with documented engineering purpose.
- The case for it:
- The RM 27-04 is the RM reference where the engineering claim is most clearly defined and tested. 30 grams total weight for a tourbillon is extraordinary. The Nadal collaboration has documented provenance -- actual professional matches worn. Secondary market is extremely strong.
- Consider instead if:
- The price is astronomical for a watch whose chief virtue -- shock resistance during professional tennis -- is irrelevant to 99.9% of buyers. The RM 27 is a correct engineering choice for Rafael Nadal and an irrational one for almost everyone else.
