The Audemars Piguet Royal Oak Concept GMT Tourbillon (ref. 26589IO.OO.D056CA.01) pushes the boundaries of technical watchmaking with a striking green aesthetic layered over avant-garde construction. Released in 2022, it pairs the industrial edge of titanium with a bold green ceramic bezel—visually echoed in the bridges and strap—for a high-impact presentation seldom seen in the Royal Oak Concept line.

The 44mm titanium case houses Audemars Piguet’s manual-winding calibre 2954, developed and finished to highlight its skeletonised architecture. The movement powers both a tourbillon and a dual-time GMT complication, delivering up to 10 days of power reserve. Green bridges command attention through the open dial, while luminescent hands and indicators retain legibility. The crown and push-piece guards continue the integration of ceramic for added durability, and the rubber strap completes the modern material palette.

Bold, architecturally audacious, and mechanically impressive, this reference underscores the Concept line’s mission to showcase AP’s experimental edge. Its unique colourway, long power reserve, and openwork calibre make it a compelling rarity in contemporary haute watchmaking.
