When Audemars Piguet introduced the Royal Oak in 1972, it fundamentally changed the landscape of luxury watchmaking. Designed by Gérald Genta, the original ref. 5402 challenged established conventions by combining a stainless steel case with the finishing, craftsmanship and price normally associated with precious metal watches. Its octagonal bezel, exposed screws and integrated bracelet created a distinctive aesthetic that would become one of the most influential designs in modern horology. The Royal Oak Chronograph, introduced in 1997 to celebrate the collection's 25th anniversary, added another dimension to this celebrated design, incorporating a mechanical chronograph without compromising the architectural character of the original.

The ref. 26715ST represents a contemporary interpretation of the Royal Oak Chronograph, combining the collection's unmistakable design with more compact proportions. Measuring 38mm in diameter and 11mm thick, its stainless steel case features the characteristic octagonal bezel, secured by eight hexagonal screws, and the integrated bracelet that has defined the Royal Oak for more than five decades. The grey Grande Tapisserie dial is complemented by contrasting silver-toned chronograph registers, creating a restrained, almost monochromatic appearance. White gold applied hour markers and Royal Oak hands provide excellent legibility, while the automatic calibre 2385 delivers chronograph functionality alongside a date display. With its carefully considered proportions and distinctive dial configuration, the ref. 26715ST offers a particularly versatile expression of Audemars Piguet's celebrated sports chronograph.
