Watch Paparazzi

Singer J Balvin spotted wearing Richard Mille

J Balvin was recently photographed wearing what may be the single most visually striking watch in his already formidable collection: a Pièce Unique Richard Mille RM 52-06 'Mask Tourbillon' crafted entirely in green sapphire crystal, with the mask set with brilliant-cut round diamonds. It is, by any measure, a watch built as much for theater as for timekeeping.

The Richard Mille RM 52-06 'Mask Tourbillon' sits within the brand's Skull and Mask series, a lineage that began with the RM 52-01 and evolved steadily toward greater mechanical integration. In the RM 52-06, Richard Mille's engineers took a definitive step: the eight arms radiating from the movement's center do not merely support the mask as a decorative appliqué — they structurally merge with it. The hand-wound tourbillon caliber features a fast-rotating barrel, a variable-geometry rotor system, and the full complement of Richard Mille's signature torque-management components. The sapphire case — front, caseback, and lateral flanks — means the movement is fully visible from every plane, an effect that becomes genuinely extraordinary in a vivid chromatic green.

For collectors, the RM 52-06 represents Richard Mille at its most uncompromising. Standard production references in the series already command stratospheric prices; a Pièce Unique in colored sapphire with diamond-set mask elevates the proposition into a different category entirely. Sapphire machining at this scale and complexity generates significant reject rates, and integrating structural movement components within the case architecture demands tolerances that few manufactures outside of Les Breuleux could achieve. The diamond setting on the mask adds a further layer of complications to an already demanding build.

J Balvin has been one of the most visible Richard Mille ambassadors in the Latin music world for several years, regularly appearing with RM references that push past conventional luxury into the realm of wearable art objects. His taste consistently runs toward bespoke and high-complication pieces, and this green sapphire RM 52-06 Pièce Unique is entirely consistent with that profile — a watch that exists nowhere else in the world.

No official retail price exists for a Pièce Unique of this specification; comparable sapphire-cased Richard Mille Pièce Unique commissions have traded privately well into seven figures. The secondary market for the standard RM 52-06 already reflects the model's scarcity and desirability, and a diamond-set, colored-sapphire unique piece operates beyond any published benchmark.
