Watch Paparazzi

Tennis player Serena Williams spotted wearing Audemars Piguet

Courtside at Melbourne Park during the Australian Open semi-finals, Serena Williams wore a watch that matched the competitive register of the occasion: the Audemars Piguet Royal Oak Offshore Diver in stainless steel, reference 15710ST. The sighting was brief but unmistakable, the 42mm octagonal case and integrated bracelet cutting through the wrist in the way only AP's Royal Oak family can.

The Royal Oak Offshore Diver 15710ST is a technically serious piece built for genuine underwater use. Its unidirectional rotating bezel — a departure from the standard Royal Oak — and screw-down crown deliver ISO 6425-certified water resistance to 300 metres. Power comes from Audemars Piguet's in-house Calibre 3120, a 60-hour power reserve movement beating at 21,600 vph with a 40-jewel construction. The skeleton rotor, visible through the exhibition caseback, is a characteristic detail collectors appreciate. At 42mm the case is assertive without being theatrical.

The reference 15710ST succeeded the original 15703ST and has since become a collector anchor within the Royal Oak Offshore family. Unlike the larger, more bombastic Offshore chronographs, the Diver occupies a niche that rewards restraint — it carries the octagonal DNA without the inflated dimensions. Several dial variants exist across the reference's run, and the stainless steel configuration consistently holds the strongest secondary market positioning relative to its original retail price.

For Serena Williams, watches have been a consistent and well-documented interest throughout her career. She has been photographed with pieces from Richard Mille, Rolex, and Audemars Piguet across major tournaments and public appearances. Choosing the Royal Oak Offshore Diver — technically rigorous, visually bold, but not ostentatious — fits the personality of an athlete who has always let performance speak louder than theatre.

At UK list price of £19,400, the Audemars Piguet Royal Oak Offshore Diver 15710ST sits at a calculated entry point for the Offshore family. On the grey market, demand for stainless steel Royal Oak Offshore references has remained resilient through broader market corrections, with the Diver regularly trading above retail among buyers who prize its functional specification alongside the AP pedigree.
