Antonela Roccuzzo, wife of footballer Lionel Messi, was photographed at Dallas Stadium on June 28, 2026, wearing the Audemars Piguet Royal Oak 1017 Alyx 9SM Ref. 15550BA.OO.1356BA.02 in 18k yellow gold. The sighting coincided with Argentina's group-stage match, where Messi extended his goal tally to six. The watch, visible on her wrist in stadium light, exemplifies the meticulous craftsmanship and design restraint that defined the collaboration between the Swiss manufacture and New York-based designer Matthew Williams.

The Royal Oak 1017 Alyx 9SM reference 15550BA.OO.1356BA.02 is a 37mm time-only piece housed in 18k yellow gold, fitted with the Calibre 2121 automatic movement. The dial features a distinctive vertically-brushed finish in yellow gold, creating a unified visual language with the integrated bracelet and case. The watch carries a water resistance rating of 50 metres and is fitted with a sapphire crystal with anti-reflective coating. Production was strictly limited to 194 pieces, underscoring the exclusivity of this collaborative offering. The bracelet is fully integrated, maintaining the seamless design philosophy that defines both the Royal Oak silhouette and Williams' minimalist aesthetic.

The 2023 Audemars Piguet and 1017 Alyx 9SM collaboration yielded four distinct references: the 37mm time-only Royal Oak in yellow gold, a Royal Oak Chronograph in yellow gold, two Royal Oak Offshore Chronographs in yellow and white gold with matching dial colours, and a one-of-a-kind Royal Oak Chronograph in two-tone yellow and white gold with black dial. The time-only 37mm variant in yellow gold remains the most cohesive representation of Williams' vision, with its unadorned dial and refined proportions striking a balance between the iconic Royal Oak geometry and contemporary minimalism.

Audemars Piguet's partnership with Matthew Williams marked a significant departure from the manufacture's prior collaboration with MAD Paris. This iteration granted Williams complete creative control, resulting in a collection that stripped the Royal Oak to its essential elements while maintaining technical integrity. The placement of both signatures—Audemars Piguet at 12 o'clock and 1017 Alyx 9SM at 6 o'clock—reinforces the visual equilibrium central to the design.

At retail, the Royal Oak 1017 Alyx 9SM Ref. 15550BA.OO.1356BA.02 commanded approximately USD 38,500. On the secondary market, examples now trade between USD 48,000 and USD 62,000, reflecting sustained collector demand for limited collaborative Royal Oak editions. The 194-piece production run and the designer's cult status have created competitive pricing in grey-market channels.
