ROYAL OAK 'CITY OF SAILS' LIMITED EDITION MODEL, REF. 25860IS, MOVEMENT NO. 462'858, CASE NO. E29154, REGISTERED IN 1999

The Audemars Piguet Royal Oak “City of Sails” ref. 25860IS is one of the most charismatic early-2000s Royal Oak limited editions, produced in circa 2000 and restricted to only 300 examples. Crafted in lightweight titanium, the watch embodies a distinctly sporty personality, created in tribute to AP’s involvement in competitive sailing and the dynamic energy of regatta culture. Its electric blue dial—vibrant, saturated, and instantly eye-catching—is paired with bold yellow accents on the hands and hour markers, a color scheme that recalls nautical signal flags while also echoing the vivid chromatic punch of the highly coveted “Yves Klein” blue Royal Oak special editions. The titanium case, combined with the integrated bracelet, lends a modern, almost futuristic feel compared to the steel models of the era, reinforcing its identity as a performance-driven Royal Oak. Exceptionally rare and seldom seen, the 25860IS stands as a collector’s gem: a visually electric and historically meaningful expression of AP’s early limited-edition creativity.
