Audemars Piguet has long been revered for their exquisitely crafted and innovative Royal Oak timepieces. Though the first Royal Oak debuted in 1972, it was not until 1982 that Audemars Piguet introduced the Royal Oak perpetual calendar, merging their expertise in perpetual calendars with the iconic octagonal design. This revolutionary combination quickly became a highly coveted reference in horology.

Audemars Piguet unveiled the ref. 26574 in 2015 as a modern interpretation of the coveted Royal Oak perpetual calendar. With a larger 41mm case and the new self-winding cal. 5134, the ref. 26574 offered increased presence on the wrist while retaining a slim profile for comfort. The handsome blue "grand tapisserie" dial contrasts elegantly with the refined white gold indices, enhancing legibility. Additionally, the 52-week indicator and photorealistic moonphase with starry skies at 6 o'clock demonstrate Audemars Piguet's dedication to fine craftsmanship.

This ref. 26574 in stainless steel is considered one of the most desirable configurations of the model. In excellent overall condition, it represents a rare chance for discerning collectors to acquire an icon of Audemars Piguet's storied legacy. Its timeless elegance and impeccable details will be appreciated for generations to come.
