Rapper Huang Zitao spotted wearing a Richard Mille

Huang Zitao — known professionally as Z.TAO — was spotted wearing the Richard Mille RM 19-01 Tourbillon Spider, a piece that occupies a category almost entirely its own within high horology. Measuring 46mm, the watch sits large on the wrist but reads more as wearable sculpture than conventional timepiece, drawing immediate attention to the translucent sapphire case that renders the movement entirely visible from every angle.

The RM 19-01 was introduced as part of Richard Mille's haute joaillerie ambitions, pushing the manufacture's engineering ethos directly into gem-set territory. The case is CNC-machined from solid sapphire crystal — one of the hardest materials used in watchmaking — demanding extreme precision because corundum cannot be corrected once cut. Inside, a manual-winding tourbillon movement sits beneath the centerpiece: a hand-crafted spider figure encrusted with diamonds, positioned on a black rhodium-plated 18k white gold baseplate set with black sapphires. The spider is not applied decoration — it is integrated into the architecture of the dial, with each stone individually placed by a single artisan over an extended period.

Collector significance for the RM 19-01 is substantial. Richard Mille produced the reference in extremely limited numbers, and its combination of case material, complication, and artistic execution places it firmly in the conversation alongside one-of-a-kind auction pieces. The sapphire case alone elevates it above most of the brand's already rarefied standard production.

Huang Zitao's relationship with Richard Mille is well documented among watch followers. His collection spans some of the rarest references the brand has produced, and he has worn pieces publicly that most collectors encounter only in auction catalogues. Within the Chinese entertainment market, his taste for extreme haute horlogerie has made him a reference point for the category.

At a declared value exceeding $1,500,000 USD, the Richard Mille RM 19-01 Tourbillon Spider has no meaningful grey market because transactions at this level are private and bespoke. Demand for sapphire-cased Richard Mille references has grown consistently, and examples that surface at auction routinely exceed their pre-sale estimates.
