The Audemars Piguet Royal Oak Double Balance Wheel Openworked reference 15467OR.OO.1256OR.01 is a 37mm luxury timepiece crafted from 18k rose gold. This model features the collection’s iconic octagonal bezel secured by eight hexagonal white gold screws and an integrated rose gold bracelet with a folding AP clasp. The case measures 10mm in thickness and includes a screw-locked crown, ensuring water resistance up to 50 meters. Its transparent sapphire crystal and caseback provide a clear view of the intricately skeletonized movement, which is finished with traditional techniques such as Geneva striping, circular graining, and hand-polished beveling on the bridges and plates.
The watch is powered by the manufacture caliber 3132, a self-winding movement that offers a 45-hour power reserve. Its primary horological complication is the patented double balance wheel geometry, which features two balance wheels and two hairsprings fixed on the same axis to improve chronometric precision and stability. The openworked dial eliminates a traditional plate to showcase this mechanism, utilizing rose gold-applied hour markers and Royal Oak hands with luminescent coating to maintain legibility against the complex mechanical backdrop.
General reviews of this reference emphasize its refined proportions, noting that the 37mm diameter offers a more versatile and elegant fit than the larger 41mm versions. Collectors and critics frequently praise the exceptional level of hand-finishing, particularly the numerous sharp interior angles found within the skeletonized bridges that cannot be achieved through automated milling. While the watch is celebrated as a masterpiece of contemporary haute horlogerie that balances technical innovation with the brand’s historic design language, some notes suggest that the busy nature of the openworked architecture can occasionally make quick time-telling more difficult compared to solid-dial models.
