The Audemars Piguet Royal Oak Concept Ref. 25980AI.OO.D003SU.01 (CW1) is a landmark in modern watchmaking, introduced in 2002 to commemorate the 30th anniversary of the legendary Royal Oak with a radical, forward-looking vision . Housed in a massive 44mm case crafted from the aerospace-grade Alacrite 602 alloy—a material used exclusively for this model and renowned for its exceptional durability and lightweight properties—the timepiece is paired with a titanium bezel and a comfortable black rubber strap . The semi-skeletonized dial offers a mesmerizing glimpse into the complex manual-winding Calibre 2896, a movement developed by the esteemed Renaud & Papi, which showcases a visible one-minute tourbillon escapement at 9 o’clock . This technical marvel is enhanced by a linear power reserve indicator spanning the right side of the dial, an instantaneous “Dynamograph” at 12 o’clock that measures mainspring torque, and a unique function selector at 6 o’clock, operated by a dedicated pusher at 4 o’clock, allowing the wearer to switch between winding, neutral, and time-setting modes . Produced in a strictly limited edition of 150 pieces, this exceptional tourbillon watch is a true collector’s grail, offering a compelling synthesis of Audemars Piguet’s mechanical mastery and daring avant-garde design . Key specifications: 44mm Alacrite case with titanium bezel; skeletonized dial with tourbillon at 9 o’clock; Calibre 2896 manual-winding movement; 70-hour power reserve; black rubber strap; 50m water resistance; limited edition of 150 pieces .
