The Royal Oak Perpetual Calendar in 18-karat sand gold introduces Audemars Piguet’s latest generation of perpetual calendar movements, the Calibre 7138—a technical tour de force housed within an iconic silhouette. The movement features three patented innovations that allow all calendar functions—day, date, month, leap year, and moonphase—to be adjusted exclusively via the crown. This intuitive interface eliminates the need for recessed pushers or adjustment tools, streamlining the user experience while preserving the case’s clean geometry. Crafted in sand gold, a warm and textured alloy exclusive to the brand, the watch strikes a refined balance between modern luxury and mechanical sophistication. This is a perpetual calendar built not only for horological purists, but for daily wear—highly technical, beautifully executed, and unmistakably Royal Oak.
