Audemars Piguet Royal Oak 16204XT.OO.1240XT.01 'Jumbo' Extra-Thin Titanium BMG Openworked Dial (2026)

Audemars Piguet Royal Oak 16204XT.OO.1240XT.01 'Jumbo' Extra-Thin Titanium BMG Openworked Dial (2026) is a skeletonized watch configured with a 39mm titanium case, an openworked dial, and an automatic movement.

The titanium/BMG combination creates distinctly modern, monochromatic aesthetic compared to warmer precious metal executions, offering cooler, more technical appearance through rhodium-toned movement contrasting against satin-brushed titanium surfaces. The self-winding Caliber 7124 measures just 2.7mm thick—among thinnest openworked automatic movements in current production—comprising 211 components with 31 jewels, operating at 28,800 vph with 57-hour power reserve. The watch is driven by Caliber 7124 measures just 2.7m.

Despite 8.1mm case thickness housing fully openworked movement, watch maintains remarkable wearability through lightweight titanium construction. The 39mm diameter honors Gérald Genta's original 1972 "Jumbo" proportions. The 39mm case measures remarkably slim 8.1mm thick despite housing the fully skeletonized self-winding Caliber 7124, representing impressive engineering achievement in ultra-thin openworked watchmaking. Glareproofed sapphire crystals protect both dial side and caseback, offering unobstructed views of the movement from multiple angles while the rhodium-toned Caliber 7124 creates cohesive monochromatic presentation. Every element demonstrates Le Brassus mastery: angled edges receive precise beveling, surfaces showcase satin brushing alternating with polished accents, and internal angles maintain sharpness despite openworked architecture. Water resistance reaches 50 meters.

The openworked dial reveals meticulous skeletonization of bridges and mainplate, precisely calculated to maintain mechanical stability while allowing light penetration—negative space determined not by decoration but structural engineering requirements. Blackened 18k white gold rectangular hour markers and matching Royal Oak hands filled with luminescent material provide contrast against the rhodium-plated movement, framed by silver-grey toned inner bezel with minute markings that visually separates the mechanism from the case architecture.

The integrated titanium bracelet with BMG studs flows seamlessly from the case with Royal Oak's characteristic design, combining brushed center links with polished BMG intermediate links creating light play across the wrist. AP three-blade titanium folding clasp secures the bracelet. Introduced early 2026, reference 16204XT represents latest material evolution for the Royal Oak "Jumbo" Extra-Thin Openworked collection—joining steel (16204ST launched for Royal Oak's 50th anniversary in 2022), white gold (16204BC), and yellow gold (16204BA) variants with advanced titanium and Bulk Metallic Glass construction.

This material combination produces distinctive visual interplay between matte grey titanium surfaces and highly reflective BMG elements, set off by polished bevels defining the octagonal geometry. This approach invites scrutiny rather than concealment—statement of confidence in Le Brassus finishing standards where every bridge, gear, and jewel receives individual hand-finishing.
