Royal Joaan Bin Hamad Al Thani spotted wearing a Richard Mille

Sheikh Joaan Bin Hamad Al Thani, the Prince of Qatar and one of the most recognizable royal watch collectors in the Gulf, was recently photographed on the wrist with one of the rarest and most structurally complex timepieces Richard Mille has ever released — the RM25-01 Tourbillon Adventure. At a UK list price of £760,000, the sighting confirms the Sheikh's place among the small circle of collectors who can access watches of this caliber at release.

The Richard Mille RM25-01 is a co-creation between the Swiss-French manufacture and Sylvester Stallone, who has been a long-standing brand ambassador and genuine design collaborator. Unlike most celebrity-branded watches, the RM25-01 is built around a genuinely functional concept: adventure readiness. The multi-component titanium and carbon TPT case integrates a liquid-filled compass, a clinometer, a folding sundial, and a small storage compartment designed to hold survival essentials — cotton, a fishing hook, a fire-starting flint. The manual-winding tourbillon movement, caliber RM25-01, runs at 21,600 vph and offers approximately 38 hours of power reserve. The case measures 50mm and is water resistant to 50 metres.

From a collector's standpoint, the RM25-01 sits in rarefied territory even within Richard Mille's already stratospheric catalog. With only 20 pieces produced globally, it is among the brand's most restrictive limited editions. The combination of the tourbillon, the integrated tool functions, and the overt collaboration pedigree places it alongside the RM27 Tennis series and the RM56 sapphire models as one of the brand's landmark statements. It is the kind of watch that does not simply sit on a waitlist — it requires an existing relationship with the maison.

Sheikh Joaan is well known in watch and motorsport circles. As the President of the Qatar Olympic Committee and a driving force behind Qatar's international sporting profile, he travels extensively and moves in the same global networks as the brand's most significant clients. His choice of the RM25-01 signals genuine engagement with the piece rather than passive acquisition.

On the secondary market, the RM25-01 commands a significant premium over its already substantial list price. The extreme production limit and the Stallone association have driven grey-market valuations well above retail, with examples — where they surface at all — trading in the region of $1.2 million to $1.5 million USD. Richard Mille's scarcest tourbillons have consistently appreciated, and the RM25-01 shows no signs of deviating from that pattern.
