In 2015, Audemars Piguet unveiled the next chapter in this lineage with the ref. 26574. Its 41 mm case offered a refined presence, while a new weekly indication enriched the dial's already generous display of information. Beneath the surface, the self‑winding cal. 5134—derived from the legendary cal. 2120—was calibrated to harmonize with the expanded dimensions, ensuring both reliability and elegance. The reference launched in four inaugural variants: pink gold and stainless steel, each offered with a choice of white or blue dials. From this foundation, the collection has since flourished.

The present example—a stainless steel ref. 26574 with a crisp white dial—represents the reference in its purest expression. Clean, refined, and unmistakably iconic, it captures the essence of the Royal Oak at its most legible and balanced. Offered in well‑preserved condition and accompanied by its full set of accessories including a winding presentation box, this timepiece presents a rare opportunity to acquire a modern classic.

Audemars Piguet

Swiss | 1881

A specialist in the manufacture of complications since it was established in 1881, Audemars Piguet never ceases to impress with a rich history of creating bold, even audacious, timepieces underpinned by traditional watchmaking at its finest. This Le Brassus-based Swiss manufacturer is one of only two major manufacturers still owned by the founding family. Since its earliest days, AP is considered a leader in the field of minute repeaters and grande complication pocket and wristwatches. The brand is devoted to preserving the history of watchmaking in the Vallée de Joux, showcased at their superb museum in Le Brassus.


Today, the brand is best known for its Royal Oak models, a revolutionary luxury sports watch launched in 1972. Other key models include early minute repeating wristwatches, vintage chronograph wristwatches, such as the oversized reference 5020, perpetual calendar watches and the Royal Oak Offshore, first introduced in 1993.
