Tennis player Roger Federer spotted wearing a Rolex

At the centenary celebrations of Wimbledon's Centre Court, Roger Federer arrived court-side wearing a watch that most dedicated collectors had never seen in the metal: the Rolex Cosmograph Daytona ref. 116588SACO in 18-carat yellow gold, set with baguette-cut orange sapphires. The choice of venue was quietly poetic — a centenary event for one of sport's most storied arenas, attended by arguably its most storied tennis champion, wearing a watch issued with virtually no public fanfare.

The ref. 116588SACO sits within Rolex's secretive non-catalogue gem-set tier, pieces that the manufacture releases selectively to its most privileged retail partners and clients without any formal press announcement or price list publication. The case measures the standard 40 mm in 18-carat yellow gold, housing the in-house Calibre 4130, a column-wheel, vertical-clutch chronograph movement with a 72-hour power reserve — the same robust and highly regarded engine found across the Daytona range since 2000. What distinguishes the 116588SACO entirely is its stones: 32 baguette-cut orange sapphires line the tachymeter bezel, while a further 11 adorn the dial chapter ring, producing a saturated citrus blaze that photographs almost aggressively warm against yellow gold.

From a collector standpoint, non-catalogue Rolex gem-set references occupy a peculiar and highly coveted category. They surface rarely at auction, appear almost never on grey-market platforms, and tend to trade on personal relationships between Rolex's authorised dealers and ultra-high-net-worth clients. The 116588SACO is particularly unusual even within this rarefied group because the orange sapphire combination was introduced with exceptional discretion — spotted by sharp-eyed observers rather than announced by the brand.

Federer's relationship with Rolex is one of the longest-standing and most prominent in sport sponsorship, dating back to 2001. He is a genuine collector beyond his ambassadorial role, regularly photographed in personal pieces that go well beyond contractual obligation. His choice to wear the 116588SACO at a high-visibility public event — rather than keep it private — effectively gave the reference its first significant mainstream exposure.

Retail pricing for non-catalogue Rolex gem-set pieces is never officially published, but informed market estimates place the 116588SACO well above $100,000 USD. Should one surface at auction or through a private dealer, strong collector demand for both the Daytona nameplate and the rarity of this specific stone configuration would likely push realised prices considerably higher.
