The new Royal Oak “Jumbo” Extra-Thin Selfwinding Flying Tourbillon Chronograph RD#5 offers a vivid glimpse into Audemars Piguet’s visionary path for complications. Limited to a mere 150 pieces, the RD#5 culminates five years of meticulous development, debuting the entirely reimagined Calibre 8100—a movement engineered to achieve the perfect harmony of slimness, ergonomics, and precision.

Measuring a refined 39mm in diameter and a slender 8.1mm thick, its titanium case with metallic glass accents faithfully preserves the original proportions that cemented the “Jumbo” as a 1972 icon, while introducing a constellation of complications unparalleled in the model’s storied lineage.

Marking the brand’s 150th anniversary, the Calibre 8100 marries the exactitude of a flyback chronograph with the finesse of a flying tourbillon. Forged from lightweight titanium and precious Bulk Metallic Glass (BMG), this limited edition signals a new epoch of horological innovation—uniting lightness, robustness, and radiance in one seamless expression.

Audemars Piguet’s new Calibre 8100 stands apart as the first Royal Oak to incorporate a flying tourbillon with a flyback chronograph, featuring a pioneering patented energy-storing reset mechanism that delivers smoother operation with less exertion. Enhanced by an innovative vertical clutch system, it introduces a low-pressure, highly ergonomic chronograph, an instant-jump minute counter, and combines advanced materials—titanium and BMG—for superior performance.

Key Features of the RD#5 include:

Patented Reset System:
The Calibre 8100 revolutionizes the chronograph reset with a patented rack-and-pinion mechanism that stores and releases energy instantaneously. This innovation ensures a fluid, precise reset requiring significantly less force, elevating user comfort and accuracy.

Flyback Function:
This rare capability allows the chronograph to be reset and restarted with a single press—an invaluable feature prized in elite chronographs.

Innovative Vertical Clutch:
Blending the strengths of traditional vertical and lateral clutches, the novel vertical clutch reduces unwanted movement and eradicates jumps in the chronograph seconds hand, guaranteeing flawless timing.

Instant-Jump Minute Counter:
The minute counter leaps instantly, a remarkable rarity that significantly enhances legibility and timing precision.

Flying Tourbillon and Integrated Functions: A First in the Royal Oak Line:
For the first time, a flying tourbillon is seamlessly integrated with a flyback chronograph in the Royal Oak collection—demonstrating unmatched technical mastery.

Ergonomic Control:
The chronograph push-pieces have been meticulously redesigned for exceptional smoothness and responsiveness, requiring approximately 25 times less pressure, offering an intuitive, effortless user experience.

Titanium and BMG Case:
The case and bracelet unite the featherweight strength of titanium with the resilience and lustrous sheen of Bulk Metallic Glass, a cutting-edge alloy renowned for its hardness and distinctive aesthetic.

“Glass Box” Crystals:
Dual “glass box” crystals accentuate the ultra-thin profile, unveiling novel perspectives of the movement while preserving structural elegance.

Visible Movement:
A peripheral oscillating weight crafted in platinum reveals the intricate chronograph mechanism, including the tourbillon, through the sapphire caseback—transforming the watch into a living showcase of haute horologerie.

The outcome is the Royal Oak “Jumbo” Extra-Thin Selfwinding Flying Tourbillon Chronograph—the pinnacle of 150 years of collaborative innovation pushing the frontiers of haute horlogerie.

Balancing technical sophistication, unparalleled performance, and iconic design, the Royal Oak “Jumbo” Extra-Thin Selfwinding Flying Tourbillon Chronograph RD#5 sets a new benchmark of ergonomic refinement, redefining the chronograph for the modern connoisseur.

This marks the fifth installment in Audemars Piguet’s RD Series—a testament since 2015 to the brand’s relentless pursuit of research and development excellence.
