Tennis player Serena Williams spotted wearing Audemars Piguet

On the courts of the USTA Billie Jean King National Tennis Center during the 2022 US Open, Serena Williams — competing in what would become one of the most emotionally charged tournament runs of her career — was spotted with a 37mm Audemars Piguet Royal Oak Offshore Quartz strapped to her left wrist. The choice of wearing a luxury timepiece mid-match is quintessentially Serena: unapologetically bold.

The reference in question is almost certainly the 67540SK.ZZ.D002CA.01, the stainless steel 37mm Royal Oak Offshore Ladies Quartz with a diamond-paved bezel. The dial displays the signature Grande Tapisserie pattern in silver, with applied baton indices and a date window at 3 o'clock — all hallmarks of the Royal Oak family. The octagonal bezel, studded with brilliant-cut diamonds seated in alternating screw-set lugs, elevates the sport-tool aesthetic into jewellery-adjacent territory without compromising the design DNA established by Gérald Genta in 1972. The case is water-resistant to 100 metres and houses a reliable Swiss quartz movement, a calibre chosen deliberately for slimness and accuracy in the ladies' configuration.

Collector opinion on the quartz Royal Oak Offshore has matured considerably. Early dismissal by purists has given way to recognition that the ladies' Offshore occupies a unique niche: genuine sport-watch architecture, precious stone setting, and Swiss manufacture quality at a price point below the automatic references. The diamond bezel variant in particular holds value well on the secondary market, driven by consistent demand from female collectors who prioritise wearability alongside horological credibility.

Serena Williams has a well-documented relationship with Audemars Piguet, befitting an athlete whose career achievements — 23 Grand Slam singles titles, four Olympic gold medals — parallel the brand's own obsessive pursuit of excellence. Wearing the Offshore during competitive play rather than a press appearance underscores her genuine affinity for the piece rather than a contractual gesture.

At an official retail price of approximately $21,500 USD, the 37mm diamond bezel Royal Oak Offshore Quartz sits at an accessible entry into the Offshore family. Grey-market pricing has remained stable, with pre-owned examples trading close to or at retail, reflecting steady organic demand. For collectors seeking an AP sport watch that pairs court-side durability with after-dark versatility, this reference delivers precisely that.
