Boxer Floyd Mayweather spotted wearing a Jacob & Co

Floyd Mayweather, boxing's undefeated pound-for-pound benchmark with a professional record of 50-0, was photographed alongside WBC super lightweight contender Adrien Broner at what appears to be a private social event. On his left wrist, the unmistakable silhouette of a Jacob & Co Astronomia Tourbillon Baguette catches the light — and it catches it aggressively, as intended.

The Jacob & Co Astronomia Tourbillon Baguette is built around the manufacture's celebrated AT110 movement, a hand-wound calibre featuring a four-arm rotating carrousel that completes one full rotation every 60 seconds. The three satellite spheres — earth globe, moon phase, and a triple-axis tourbillon at 6 o'clock — orbit a central sun wheel, transforming the dial into a kinetic sculpture. The case measures 47mm in diameter, and in this specific iteration every surface — bezel, bracelet links, case flanks — is paved with baguette-cut white diamonds. The dial itself deploys yellow sapphires or citrines in a honeycomb arrangement, creating the warm amber glow visible in the reference image, earning the 'Rainbow' designation for its chromatic contrast against the icy white diamond exterior.

From a collector's standpoint, Jacob & Co Astronomia pieces occupy a singular niche: they are not purchased for subtlety or investment liquidity, but as wearable kinetic art. The Baguette variant represents the highest expression of Jacob Arabo's founding philosophy — maximum visual impact married to legitimate haute horlogerie complications. Independent watchmaking critics have acknowledged the AT110 movement's genuine technical merit despite the brand's flashy reputation.

Mayweather's relationship with Jacob & Co is long-documented. He is among the brand's most visible ambassadors globally, having worn numerous Astronomia references at press conferences, fights, and public appearances. His taste runs consistently toward full-pavé diamond executions, and this Rainbow Tourbillon Baguette sits at the apex of even his considerable collection.

Market pricing for this reference is effectively academic — pieces of this specification are produced in extremely limited quantities, often as single commissions, making secondary market comparables rare. The £1.3 million UK list price translates to approximately $1.65 million USD at current exchange rates. Grey-market activity is negligible given the bespoke nature of each piece.
