Audemars Piguet Royal Oak Chrono Steel Blue Dial — USD 55,297

The Audemars Piguet Royal Oak Chronograph reference 26331ST was introduced in 2017 to commemorate the 20th anniversary of the Royal Oak Chronograph line. This reference updated the previous 26300ST and 26320ST models, bringing subtle but significant design refinements to the dial, including enlarged chronograph registers and a redesigned minute track. It represents a key evolution in the chronograph sub-collection, maintaining the established aesthetic while enhancing legibility and balance. This particular reference was available in several dial configurations, catering to diverse collector preferences. This chronograph features a 41mm stainless steel case with the characteristic octagonal bezel secured by eight hexagonal screws. The watch is powered by the self-winding Caliber 2385, a column-wheel chronograph movement. It is fitted with a glareproofed sapphire crystal and a screw-locked crown, ensuring a water resistance suitable for daily wear. The integrated stainless steel bracelet is a hallmark of the Royal Oak design, providing both comfort and a cohesive aesthetic. For collectors, the 26331ST is notable for its refined dial aesthetics and its position as the last iteration of the 41mm Royal Oak Chronograph to use the Caliber 2385 before the introduction of the in-house Caliber 4401 in later models. Its production run saw various dial colors, making certain combinations more sought after than others. This reference appeals to those who appreciate the classic Royal Oak design combined with the added functionality of a chronograph, representing a significant chapter in the model's history.
