Rapper Drake spotted wearing a Jacob & Co

Drake was photographed at a private evening event, cocktail in hand, with an 18K rose gold Jacob & Co Astronomia Casino 'Gambler' secured to his wrist — one of just 18 examples ever made. The sighting is notable not simply for the watch's eye-watering price point, but for what it represents mechanically: a wristwatch that functions, quite literally, as a roulette wheel.

The Astronomia Casino sits at the apex of Jacob & Co's Astronomia collection, itself launched in 2014 as a showcase of haute horlogerie spectacle. The dial is dominated by all 37 squares of a regulation roulette wheel — numbered 0 through 36 — rendered in green, red, and black enamel with mahogany inlays. A steel ball orbits the wheel when activated, mimicking a real casino spin. Beneath this theatrical centrepiece, the proprietary JCAM09 movement operates with a 60-hour power reserve, driving a triple-axis tourbillon that completes a full rotation every 10 minutes, 5 minutes, and 2.5 minutes on its respective axes. A blue aventurine glass sphere representing Earth and a white crystal ball complete the four-armed rotating satellite complication — a hallmark of the Astronomia architecture.

The case measures 47mm in 18K rose gold, with a domed sapphire crystal that provides an almost aquarium-like view of the movement's constant motion. The reference — most consistent with AT110.40.AA.AA.A in rose gold — is exceedingly rare in collector circles, with scarcely any public auction appearances to benchmark secondary pricing against.

For Drake, this is entirely consistent with a collection that includes multiple Patek Philippe complications, AP Royal Oak Perpetual Calendars, and custom Rolex pieces. The Astronomia Casino is not a watch for the horologically indifferent — its owner is expected to understand exactly what they are wearing. Drake, who has publicly spoken about his passion for watches, clearly does.

With a UK list price around £475,000 — translating to approximately $580,000 USD — and production capped at 18 pieces globally, the Astronomia Casino 'Gambler' occupies a category where grey-market pricing is largely academic. These watches move privately, if at all, and finding one requires relationships, not just resources.
