Takashi Murakami wearing Hublot
Hublot Big Bang Unico Sapphire Rainbow 45mm Ref. 411.JX.4803.RT.4099 – Limited to 50 Pieces
The Hublot 411.JX.4803.RT.4099 has so far turned up on two very different kinds of public figure: Takashi Murakami, the Japanese contemporary artist whose work spans painting, sculpture, and fashion collaborations, and Alicia Keys, the Grammy-winning singer-songwriter and producer. That pairing — a visual artist and a musician — is telling. Neither fits the profile of the typical watch collector drawn purely to mechanical tradition. Both are known for making deliberate, considered aesthetic choices in public, which suggests the 411.JX.4803.RT.4099 is pulling in wearers who respond specifically to its visual statement rather than to horological heritage alone.
Demand for the 411.JX.4803.RT.4099 has consistently outpaced supply since the reference was introduced. At retail, Hublot has priced it in the range of roughly $90,000 USD, but authorized dealer availability has been extremely limited, and the watch regularly trades on the secondary market at a significant premium. The combination of a fully transparent sapphire case and a bezel set with gradient rainbow-colored sapphire stones creates a production challenge that keeps output low, which reinforces its scarcity value. For buyers who cannot access it through boutiques, auction results and grey-market platforms have reflected sustained appetite.
The 411.JX.4803.RT.4099 is a 45mm Big Bang Unico built entirely from synthetic sapphire crystal and fitted with an in-house HUB1242 flyback chronograph movement visible through the case. Murakami's sighting in particular helped draw attention to the reference outside traditional watch media, connecting it to an audience that follows contemporary art and streetwear culture as closely as it follows horology.
