A new material dialogue for the Royal Oak’s most refined openworked Jumbo.
We closely and thoroughly examined the Royal Oak “Jumbo” Extra-Thin Openworked when it was introduced in steel (16204ST) for the RO´s 50th anniversary, for the model has become a reference for how Audemars Piguet approaches skeletonisation within an icon. Since then, it has been followed by precious-metal executions in white gold (16204BC) and yellow gold (16204BA). For 2026, AP expands the family again with the reference 16204XT, introducing a new material combination.
This latest Royal Oak “Jumbo” Extra-Thin Openworked keeps the familiar 39mm Jumbo form intact but replaces precious metal or steel with titanium and Bulk Metallic Glass (BMG). BMG, a palladium-based amorphous alloy, is used for the bezel and caseback frame, where its mirror-like polish and high scratch resistance contrast with the satin-brushed titanium mid-case. The screw-locked crown is made from titanium to maintain coherence, and the sapphire caseback allows a view of the movement. The case dimensions remain unchanged: 39mm in diameter, 8.1mm thick. Water resistance is 50m.
The dial side is where visual evolution happens. The openworked Calibre 7124 is rhodium-toned, creating a monochromatic backdrop. Compared to earlier openworked Jumbos, which relied on warmer tones or stronger contrast, this version offers a cooler, more technical aesthetic. To make the openworked dial readable, AP uses blackened 18-carat white gold hour markers and hands, filled with luminescent material. A silver-grey inner bezel with minute markings frames the skeletonised calibre, as if separating the movement from the case.
Movement-wise, nothing changes. Calibre 7124 remains one of the thinnest (2.7mm) self-winding openworked movements currently in production. It operates at 28,800 vibrations/hour and offers a 57-hour power reserve. The movement’s openworked bridges, sharp internal angles and alternating finishes remain a showcase of AP’s skeletonisation expertise, visible from both sides.
The integrated bracelet follows the materials logic of the case, with titanium links and BMG studs. Like its predecessors, the Royal Oak Jumbo Extra-Thin Openworked 16204XT is not a limited edition, but production will be tightly controlled. Availability is expected to follow Audemars Piguet’s usual boutique-driven allocation; the price is upon request.

Hmmmm, I’d say this is skeletonized rather than openworked. The primary mechanisms aren’t necessarily brought to the fore as much as the bridges expose the workings beneath.
