Watch Paparazzi

Rapper Huang Zitao spotted wearing Richard Mille

Huang Zitao, the Chinese rapper and media personality known professionally as Z.TAO, was recently photographed wearing a Richard Mille RM53-02 Tourbillon in full sapphire crystal — a piece so rare that fewer than ten collectors in the world own one. The sighting adds another extraordinary chapter to Zitao's well-documented history of wearing seven- and eight-figure timepieces in casual public settings.

The RM53-02 builds on Richard Mille's Pablo Mac Donough polo-themed lineage, but its defining feature is the case itself. Grade-5 sapphire — the same material used for watch crystals but machined into a full three-dimensional structure — forms both the bezel and caseback, achieving a Vickers hardness of approximately 2,000 HV, second only to diamond. The process of milling and polishing a single sapphire case takes several months and generates enormous material waste, which explains a significant portion of the price. Inside sits a manually wound tourbillon calibre engineered to absorb the mechanical shocks specific to polo play, mounted on a titanium baseplate. The result is a watch that is simultaneously brutally technical and visually transparent — every component, spring, and cage exposed beneath the colourless sapphire shell.

Among serious collectors, the RM53-02 in sapphire occupies a specific tier: it is not simply expensive, it is effectively unobtainable. Richard Mille produced just ten examples, and the brand's allocation network means the vast majority never reach the open market. Pieces in this sub-family rarely surface at auction, and when they do, hammer prices have significantly exceeded list. The combination of sapphire architecture, tourbillon complication, and a double-digit global edition size makes it a benchmark conversation piece at any collector gathering.

Zitao, who has previously been spotted in Audemars Piguet Royal Oak Offshore models and standard-grade Richard Mille pieces, is escalating into genuinely museum-level territory with the RM53-02. His profile in mainland China and across Asian entertainment markets gives this sighting considerable reach — Richard Mille's positioning in the region has long been tied to exactly this kind of high-visibility celebrity association.

With a UK list price of approximately £1.6 million and a production run of ten pieces, a meaningful secondary-market price is almost theoretical — there is no functioning grey market for a watch this scarce. The few transactions that have occurred privately suggest a premium over list, placing realistic acquisition cost well north of $2 million USD for any buyer determined enough to find one.
