Model Antonela Roccuzzo spotted wearing a Audemars Piguet

Antonela Roccuzzo was photographed at Day One of the 2026 US Open as a guest of Adidas wearing the Audemars Piguet Royal Oak Selfwinding Tourbillon Extra-Thin ref. 26660ST, a 37mm stainless steel sports watch that exemplifies contemporary ultra-thin automatic tourbillon design. The plum petite tapisserie dial—a distinctive colorway released in 2022—catches light across its textured surface, while the visible flying tourbillon sits flush at the 6 o'clock position.

The ref. 26660ST belongs to Audemars Piguet's "Research and Development" (RD3) series, introduced in 2022 as a technical refinement of the celebrated Royal Oak Jumbo proportions. This model reduces the Jumbo's 39mm diameter to 37mm while maintaining the iconic octagonal case profile and integrated bracelet. Constructed entirely in stainless steel, the watch measures just 8.1mm thick—a feat achieved through the calibre 2968, an in-house automatic movement measuring only 3.4mm in height. The movement features a flying tourbillon with a new geometric cage design that allows the regulating organ to sit level with the dial surface, eliminating the traditional stepped appearance.

Water resistance stands at 20 metres, appropriate for a dress sports watch prioritising thinness over diving capability. The movement oscillates at 4 Hz and provides approximately 70 hours of power reserve. The stainless steel bracelet terminates in a folding clasp, and the bezel remains the signature octagonal AP bezel in polished steel. Unlike the ref. 26670ST released simultaneously in 2022, which retained the 39mm Jumbo diameter, the 26660ST's more compact proportions and distinctive plum tapisserie dial created a differentiated offering within the RD3 collection.

The Royal Oak Selfwinding Tourbillon Extra-Thin ref. 26660ST occupies a unique position in modern haute horlogerie. It competes directly with Patek Philippe's Nautilus Automatic Tourbillon and Omega's Co-Axial Tourbillon offerings, yet maintains distinct aesthetic and technical credentials through its reduced dimensions and visibility-forward tourbillon positioning. The plum dial variant remains a limited release, making Roccuzzo's wrist appearance noteworthy among collectors tracking RD3 colour variants.

Retail pricing for the ref. 26660ST with standard dials typically ranges from $65,000 to $70,000 USD. The plum petite tapisserie dial variant commands significant grey-market premiums, with recent sales in the $75,000–$85,000 range. Waitlist periods at authorised retailers often exceed two years for this reference. Pre-owned examples, particularly in the distinctive plum colourway, trade actively on specialist platforms and maintain strong secondary-market demand.
