Born from Richard Mille's long-standing collaboration with 22-time Grand Slam champion Rafael Nadal, the RM 27-04 centers on a manual-winding tourbillon movement — caliber RM27-04 — suspended inside the case by braided steel cables tensioned across the interior. This architecture is a defining characteristic of the RM 27 lineage, conceived to protect the movement against the extreme forces generated during match play.
The 38.40 x 47.25mm tonneau case is constructed from Carbon TPT and titanium, with a matching Carbon TPT and titanium bezel and a sapphire crystal that lays bare the skeletonized black dial beneath. The exposed tourbillon sits at the heart of the open-worked layout, its cable connections visible from the front. A screw-locked crown, titanium folding clasp, and textile strap round out the athlete-oriented specification. Water resistance is rated to 50 meters.
The RM 27-04 delivers the hours, minutes, and tourbillon functions that define this reference within the Richard Mille catalogue. For collectors drawn to athlete-collaboration pieces and high-complication engineering, it occupies a distinct position in the broader RM tourbillon range.
