Audemars Piguet Royal Oak Chronograph Kasparov 25860ST Blue Dial Box AP Service

Reference 25860 arrived in the late 1990s as the first chronograph in the classic Royal Oak line, bringing stopwatch functionality to the original integrated-bracelet design without adopting the larger proportions of the Royal Oak Offshore. Its 39 mm case preserved the compact presence associated with early Royal Oak models. The reference became known among collectors as the “Kasparov,” reflecting Audemars Piguet’s association with chess champion Garry Kasparov.

This stainless steel example, reference 25860ST.OO.1110ST.04, pairs a 39 mm case and integrated bracelet with a blue tapisserie-pattern dial, luminous baton markers, three recessed chronograph registers, and a date display positioned between four and five o’clock. It is powered by the selfwinding Audemars Piguet caliber 2385, providing hours, minutes, small seconds, date, and chronograph functions. The watch was recently serviced by Audemars Piguet and is accompanied by its box and AP service papers. The original warranty papers are not included.

The watch is in overall very nice condition and presents beautifully on the wrist. Very minimal signs of wear are visible to the case, there may be light handling marks apparent. The bracelet shows light signs of prior use consistent with the watch’s overall presentation. Please review the photographs closely for the most complete representation of condition.
