Estimate: € 20,000 –⁠ 40,000

The Audemars Piguet Royal Oak Offshore, reference 25721ST, is an icon of modern horology, introduced in 1993 as a bold evolution of the legendary Royal Oak in celebration of its 20th anniversary. Designed to embody a more robust and contemporary aesthetic, the Offshore earned the nickname “The Beast” for its oversized 42 mm stainless steel case and integrated steel bracelet with thick rounded links. This particular example, numbered 1830 and accompanied by an Extract from the Archives, is one of the earliest iterations of the Offshore model, showcasing a revolutionary design that set the stage for the popularity of larger wristwatches in modern watchmaking. The watch features a chronograph function with silicone-capped pushers and crown, a visible gasket between the bezel and the case, and the signature guilloché “Tapisserie” dial. What makes this piece truly exceptional is the transformation of its original electric blue dial into a highly coveted tropical brown hue, a natural rarity that adds immense collector value and aesthetic charm. The dial retains the hallmark design elements of the Royal Oak family, blending tradition with the boldness of the Offshore series. The Royal Oak Offshore is not merely a timepiece; it represents a watershed moment in Audemars Piguet’s history, bridging the gap between classic elegance and modern innovation, making this rare tropical-dial example a remarkable testament to the enduring legacy of the brand.
