Audemars Piguet 25860ST Royal Oak Chronograph SS Blue Dial

This Audemars Piguet Royal Oak Chronograph reference 25860ST.OO.1110ST.03 belongs to the earlier, more compact phase of the model before later chronographs grew larger.Its self-winding calibre 2385, built on the Frédéric Piguet 1185, adds a date between four and five o'clock to the chronograph's 30-minute and 12-hour counters, and for a collector who prefers the line closer to its original proportions that matters more than novelty. In stainless steel, the case measures 39mm across and 11mm thick, a size that keeps the watch crisp and controlled on the wrist. The blue Grande Tapisserie dial gives this reference one of the strongest configurations in the series, setting the technical layout against the Royal Oak's familiar architecture. More broadly, the 25860ST stands at the point where the Royal Oak Chronograph still felt tied to the scale that defined the line in the first place. That makes it less a later expansion of the design than a complication added without losing the restraint that made the Royal Oak endure. This Royal Oak was just fully serviced by Audemars Piguet in Q3/2026.
