Footballer Kaká spotted wearing a Tiffany & Co.

On 9 November 2024, Ricardo Izecson dos Santos Leite—widely known as Kaká—was formally inducted into the AC Milan Hall of Fame during a Serie A derby. The Brazilian footballer, one of the club's most decorated players, wore a 30 mm yellow gold Tiffany & Co. Union Square on his wrist as he received the honour. The timepiece, paired with a platinum and gold Jean Schlumberger brooch set with tsavorite, diamonds, and pink sapphire, underscored the ceremonial significance of the moment.

The Tiffany & Co. Union Square represents the jeweller's entry into serious watchmaking during the mid-20th century. The 30 mm version, housed in yellow gold, features a square case with rounded lugs—a geometry that distinguishes it from Tiffany's other dress watch designs. The watch is powered by an automatic movement housed beneath an anti-reflective sapphire crystal. The white dial features applied Arabic numerals in gold, stick indices, and a date window, complemented by a brown crocodile leather strap with a gold clasp. Water resistance is rated to 30 metres, appropriate for a dress watch intended for formal wear rather than aquatic pursuits.

The Union Square occupies a distinct position in Tiffany & Co.'s watch portfolio. Unlike the brand's more minimalist designs, the Union Square embraces classical proportions and a legible dial layout suited to professional settings. The 30 mm case—now less common as the brand has shifted toward larger diameters—carries particular appeal among collectors seeking vintage-inspired dimensions and refined yellow gold construction. Limited production runs and discontinuation of certain references have strengthened secondary-market demand.

Kaká's appearance at the AC Milan ceremony marked a significant moment for both player and institution. His 307 appearances, 104 goals, and 2007 Ballon d'Or alongside the Champions League trophy exemplify his contribution to the club's modern history. That Tiffany & Co. also serves as the official trophy maker for the AC Milan Hall of Fame—crafting the award Kaká received—reinforced the symbolic weight of the occasion and the watch selection.

On the grey market, yellow gold Tiffany & Co. Union Square watches in 30 mm typically trade between $4,500 and $6,500 USD, depending on condition, movement service history, and strap provenance. Retail pricing through Tiffany & Co. for new production pieces remains significantly higher, though production of this specific reference is no longer active, making pre-owned examples the primary acquisition route for collectors.
