The Royal Oak 15467OR.OO.1256OR.01 represents Audemars Piguet’s technical and aesthetic achievement showcasing the patented double balance wheel mechanism through full openworked architecture visible from both dial and caseback, demonstrating the manufacture’s commitment to innovation since the original Royal Oak designed by Gérald Genta revolutionized luxury sports watches in 1972. The double balance wheel system employs two balance wheels and two hairsprings mounted on the same axis rotating in opposite directions to improve chronometric performance by averaging rate deviations and compensating for gravitational effects, making this complication both functionally superior and visually spectacular when revealed through skeletonization that removes all unnecessary material from bridges and mainplate while maintaining structural integrity. Sized at 37mm to bridge traditional dress watch proportions and contemporary sports watch dimensions, this reference appeals to collectors who value both cutting-edge horological innovation and the artistic craftsmanship of openworked movement finishing combined with iconic Royal Oak design language.
The 37mm case crafted in 18-karat rose gold features the iconic octagonal bezel with eight exposed white gold hexagonal screws, brushed surfaces on bezel top and case band contrasting with polished chamfers, integrated lugs flowing seamlessly into bracelet construction, screw-locked crown, glareproofed sapphire crystal, and transparent sapphire caseback revealing the extensively openworked movement from reverse angle. The openworked rhodium-toned dial reveals the intricate architecture of the self-winding Caliber 3132 movement with visible double balance wheel system oscillating at 9 o’clock position, skeletonized bridges and mainplate finished with circular graining and polished bevels, applied rose gold hour markers with luminescent coating maintaining Royal Oak design vocabulary, rose gold Royal Oak hands with luminescent fill, small seconds subdial integrated into movement structure, all mechanical components visible through strategic openworking creating mesmerizing depth and dimensional complexity. Inside beats the automatic Caliber 3132 featuring the patented double balance wheel mechanism with two balance wheels and two hairsprings mounted coaxially for enhanced precision, 38 jewels, frequency of 21,600 vibrations per hour, approximately 45 hours of power reserve, movement components constructed with extensive hand-finishing including circular graining, perlage, polished bevels. Rose gold integrated Royal Oak bracelet with alternating brushed and polished surfaces secures with AP folding clasp.
*This timepiece comes with the original factory stickers on the inner side of the bracelet.
