Royal Ammar bin Humaid Al Nuaimi spotted wearing a Richard Mille

Sheikh Ammar bin Humaid Al Nuaimi, Crown Prince of Ajman and a figure regularly seen alongside significant timepieces, was recently spotted wearing the Richard Mille RM35-01 Rafael Nadal Last Carbon Edition — a watch that marks the formal close of one of modern watchmaking's most commercially and technically impactful partnerships. The sighting adds the RM35-01 to a growing list of high-complication Richard Milles gravitating toward Gulf royal wrists.

The RM35-01 houses a manually wound calibre RMAL1 skeletonised movement featuring a variable geometry rotor and a free-sprung balance wheel with variable inertia. It operates at 4 Hz (28,800 vph) and delivers approximately 55 hours of power reserve. The case is constructed from NTPT Carbon — North Thin Ply Technology — layers of parallel carbon filaments fused under high pressure, producing the unmistakable marbled black-grey finish and an exceptional strength-to-weight ratio. The tonneau-shaped case measures 48.15 mm × 38.45 mm, yet tips the scale at just over 33 grams complete.

The 'Last Carbon Edition' designation carries genuine collector significance. Richard Mille introduced the RM35-01 in 2013 as Nadal's on-court companion — the Spaniard famously wore it during match play, making extreme mechanical endurance part of the product's identity rather than its marketing. The 'Last Carbon' variant closed that chapter as Nadal's professional career wound down, giving the reference a narrative endpoint that limited editions rarely achieve with this kind of authenticity. Production numbers are tightly controlled, and original owner demand has been commensurately firm.

Sheikh Ammar is no stranger to technically demanding timepieces. The Crown Prince of Ajman has cultivated a visible horological profile over the years, and the choice of the RM35-01 over the more theatrical RM27 tourbillon series suggests a preference for wearable legibility married to serious engineering — exactly the brief Richard Mille built the RM35 line to fulfil.

At a UK list price of £120,000 — approximating $150,000 USD at current exchange — the RM35-01 Rafael Nadal Last Carbon Edition sits firmly in Richard Mille's mid-tier despite its complexity. On the secondary market, demand for Last Carbon-designated references has kept grey prices at or above retail, with clean examples trading between $155,000 and $175,000 USD depending on provenance and completeness of set.
