Boxer Floyd Mayweather spotted wearing a Hublot

Floyd Mayweather has never been shy about his wrist, and this sighting is among his most technically interesting. The boxer — whose collection spans Patek Philippe complications, Richard Mille sports models, and custom Rolexes — was photographed wearing the Hublot Big Bang Unico Sapphire Baguette Diamonds, reference 411.JX.4802.RT.1904, a watch that pushes case manufacturing to its practical limits and exists in an edition of just 50 pieces globally.

The ref. 411.JX.4802.RT.1904 measures 45mm and is built around a case, bezel, and lugs machined entirely from polished sapphire crystal — the same material used for watch crystals, rated 9 on the Mohs hardness scale. Machining sapphire into three-dimensional case components requires diamond-tipped tooling and generates significant waste, which explains both the rarity and the price. Baguette-cut diamonds are then channel-set into the bezel and lugs, creating a contrast between the icy transparency of the sapphire and the faceted brilliance of the stones. Inside sits Hublot's manufacture Calibre HUB1242 UNICO, a 330-component column-wheel flyback chronograph movement with a 72-hour power reserve, visible in its entirety through the sapphire architecture.

Hublot introduced its first full sapphire Big Bang in 2016, and the subsequent diamond-set iterations rapidly became among the most sought-after references in the brand's catalogue. The combination of an open-worked manufacture movement, an exotic case material, and a meaningful production limit of 50 pieces positions the 411.JX.4802.RT.1904 as a serious collector's object rather than a mere status accessory — though it functions as both without apology.

Mayweather's relationship with high-horology is well documented. He has gifted Hublots to training partners, worn seven-figure Pateks to press conferences, and routinely appears with pieces that reflect genuine market knowledge rather than simple brand recognition. His choice of the sapphire Hublot Big Bang Unico aligns with a broader pattern: technically complex, visually arresting, and deliberately rare.

With a UK list price of approximately £73,000 — translating to roughly $92,000 USD at prevailing rates — the Hublot Big Bang Unico Sapphire Baguette Diamonds ref. 411.JX.4802.RT.1904 trades at or above retail on the secondary market when examples surface, given the 50-piece limitation. Liquidity is understandably thin, but collector demand for transparent-case Hublot references with diamond setting has remained consistent.
