Influencer Dee Devlin spotted wearing a Cartier

Dee Devlin, longtime partner of UFC superstar Conor McGregor, was recently spotted wearing a Cartier Ballon Bleu de Cartier WJBB0031 gifted directly by McGregor — a gesture consistent with the couple's well-documented appreciation for serious luxury timepieces. The watch appeared on a purple leather strap, a detail that underscores Cartier's signature approach of offering bold strap options to personalise even their most opulent references.

The Ballon Bleu de Cartier collection debuted in 2007 and rapidly became one of the maison's most commercially and critically successful modern designs. Its defining architectural feature — a curved crown integrated into the case flank and protected by a soldered arc — gives the watch its characteristic rounded silhouette and lends the collection its name. The WJBB0031 sits at the top of the standard Ballon Bleu hierarchy: an 18-carat yellow gold case measuring 42mm in diameter, set with 126 brilliant-cut diamonds totalling 1.83 carats across the bezel and case. The fluted crown is finished with a sapphire cabochon, a Cartier hallmark traceable to the brand's Art Deco archives. The lacquered silvered guilloché opaline dial is powered by Cartier Manufacture Calibre 1847 MC, an in-house automatic movement beating at 28,800 vph with a 42-hour power reserve.

From a collector standpoint, the WJBB0031 occupies a specific niche: it is a jewellery watch that wears convincingly as a dress timepiece rather than a purely decorative object. The 42mm case size, which Cartier also produces in 36mm and 33mm variants, gives the diamond-set version genuine wrist presence without reading as overtly feminine — a factor that broadens its appeal across genders.

Dee Devlin maintains a significant social media following and is closely associated with McGregor's public image, meaning a sighting of this calibre carries real visibility. McGregor himself has long favoured Audemars Piguet and Richard Mille, but gifting a Cartier of this specification signals an understanding of distinct horological registers.

At an official retail price of $45,000 USD, the Cartier Ballon Bleu WJBB0031 commands a premium consistent with its all-gold, diamond-set construction. On the secondary market, yellow gold Ballon Bleu references with full diamond settings have held value steadily, supported by Cartier's enduring brand equity and consistent collector demand for wearable jewellery complications.
