About the Audemars Piguet AP 2385

The 1185 is one of the thinnest automatic chronographs ever made, at 5.5 mm, with a column wheel and a vertical clutch in a 26.2 mm diameter, and it is what allowed a chronograph to sit in a Royal Oak case without spoiling the proportions. Audemars Piguet's version runs at 21,600 vph with a 40-hour reserve and 37 jewels, with a date at 4 o'clock and the small counters that give the Royal Oak Chronograph its face. The in-house 4401 replaced it in 2021.

In the library it sits under 77 Royal Oak chronographs, the 39 mm 25860 and 26300, the 41 mm 26320 of 2012 and the 38 mm 26315, 41 Royal Oak Offshore references in the 37 mm ladies' case and 2 Millenarys. The 37 mm case accounts for 40 references, the 41 mm for 34 and the 39 mm for 28. 33 are limited editions.

The 3126/3840 is the modular chronograph the larger Offshores used over the same years, and the glossary defines the chronograph.
