Actor Pierre Png spotted wearing a Jacob & Co

Singaporean actor Pierre Png, best known internationally for his role in the hit film 'Crazy Rich Asians,' was recently photographed wearing what is arguably one of the most mechanically spectacular watches in existence: the Jacob & Co Bugatti Chiron Sapphire Crystal Tourbillon. The watch's transparent case renders its extraordinary movement completely visible, and the combination of blue accents and white rubber strap — mirroring Bugatti's iconic livery — makes it instantly recognisable against any backdrop.

At the heart of the Jacob & Co Bugatti Chiron Sapphire sits the manually wound calibre JCAM37, a movement that does far more than tell time. The 578-component mechanism replicates the architecture of Bugatti's legendary 8.0-litre W16 quad-turbocharged engine, complete with a functioning crankshaft, 16 pistons in reciprocating motion, and a balance wheel visible at 12 o'clock. The engine block sits centrally in the case, spinning at up to 6Hz, with the visual effect of a revving powerplant achieved in real time on the wrist. Power reserve stands at approximately 60 hours. The case itself is carved from a solid block of sapphire crystal — a process requiring over 200 hours of machining — with blue-anodised titanium accents referencing the Chiron hypercar directly.

The Bugatti Chiron Sapphire is limited to a mere seven examples globally, a number that underscores its position not merely as a watch but as a collectible object on par with bespoke automotive art. Jacob & Co's collaboration with Bugatti, which began with the earlier Chiron Tourbillon, reached its apex with this sapphire variant, which debuted and immediately commanded the attention of serious collectors and auction houses alike. Each piece is individually numbered and comes with bespoke documentation.

Pierre Png is no stranger to luxury goods — his public profile rose sharply following 'Crazy Rich Asians,' a film whose very premise celebrated ultra-high-net-worth Asian culture. His choice of the Jacob & Co Bugatti Chiron Sapphire is therefore entirely on-brand, signalling genuine collector sensibility rather than mere celebrity gifting.

On the secondary market, the Jacob & Co Bugatti Chiron Sapphire has not appeared at major public auction at the time of writing, given its extreme rarity. With a list price of approximately $1.5 million USD and only seven examples ever produced, any secondary transaction would almost certainly command a significant premium over retail. This is not a watch that depreciates.
