Watch Paparazzi

Actor Matthew Macfayden spotted wearing Cartier

In HBO's Succession, every costume detail is deliberate, and Tom Wambsgans's wrist is no exception. Matthew Macfadyen's character — a man perpetually performing wealth he hasn't quite earned — wears what appears to be a Cartier Ballon Bleu with a black dial and black leather strap. The illusion holds at broadcast resolution, but still-frame analysis reveals lug geometry that departs noticeably from Cartier's production specifications, confirming the piece as a high-quality prop rather than a genuine reference.

The watch it imitates is the Cartier Ballon Bleu 42mm in stainless steel with a black Roman-numeral dial — most likely approximating reference W69012Z4 or the newer WSBB0003 variant. The genuine article houses Cartier's in-house Calibre 1847 MC automatic movement, 25 jewels, 3Hz beat rate, and 42-hour power reserve. The signature sapphire-set winding crown set into a protective arc at 3 o'clock, the sunray-brushed black dial with blued steel hands, and the distinctive balloon-curve case make it one of Cartier's most recognisable modern dress references since its 2007 introduction.

Among collectors, the Ballon Bleu occupies a curious middle ground: broadly beloved by the mainstream for its elegant proportions and instantly legible Cartier DNA, yet sometimes overlooked by hardcore horology circles who favour the Tank or Santos lineages. The black dial 42mm configuration is nonetheless among the more desirable iterations — understated, versatile, and substantially more striking than the white or silver variants at formal occasions.

The prop team's choice to replicate rather than source a genuine Ballon Bleu for Tom is, whether intentional or not, a perfect character note. Tom Wambsgans spends four seasons performing authenticity he doesn't possess — marrying into the Roy dynasty, mimicking its power codes, wearing its signifiers. A simulacrum Cartier on his wrist is almost too neat a metaphor to be accidental.

On the secondary market, a genuine stainless Ballon Bleu 42mm with black dial trades comfortably in the $6,500–$8,500 range depending on condition and box/papers. Retail list price for the closest current production reference sits around $8,150. The prop version: priceless in narrative terms, worthless at auction.
