Rapper Sfera Ebbasta spotted wearing a Audemars Piguet

Spotted leaning back in the cabin of what appears to be a Rolls-Royce, Italian rapper Sfera Ebbasta raises a tattooed hand to reveal the unmistakable octagonal case of an Audemars Piguet Royal Oak Double Balance Wheel Openworked in stainless steel — one of the more technically serious pieces circulating in the celebrity watch orbit right now.

The watch in question is reference 15407ST.OO.1220ST.01, a 41mm stainless steel Royal Oak housing the Calibre 3132 automatic movement. That movement is the real story here: AP engineered it with two separate balance wheels and two lever escapements working in concert, a system that reduces positional errors and improves chronometric performance without resorting to a tourbillon. The 245-component movement is finished to haute horlogerie standards, with the rose gold balance bridge serving as the visual centrepiece of the openworked slate grey dial. Rose gold applied hour-markers and Royal Oak hands with luminescent coating frame the mechanical spectacle beneath.

The Double Balance Wheel Openworked debuted at SIHH 2016 and was positioned as AP's answer to collectors who wanted serious movement architecture in the Royal Oak's sporting DNA. Unlike a skeleton watch that simply cuts away material for aesthetic effect, the 3132 was architecturally redesigned for openworking — bridges and plates were reengineered from scratch rather than hollowed out. That distinction matters to serious collectors and underpins the model's strong market performance.

Sfera Ebbasta, whose real name is Gionata Boschetti, is arguably the most internationally successful Italian trap artist of his generation, with streaming numbers that rival major Anglo-American acts. His watch choices tend toward high-complication AP and Patek Philippe — pieces that signal fluency with haute horlogerie rather than simple brand recognition. Wearing a technically complex openworked Royal Oak rather than a diamond-set equivalent suggests genuine collector sensibility.

At official retail the 15407ST lists at $68,500, but grey market demand has pushed trading prices to approximately $145,000 — a premium of more than 100% that reflects both AP's constrained production allocations and sustained collector demand for openworked steel Royal Oaks. For a piece introduced less than a decade ago, that trajectory is exceptional.
