Royal Oak Chronograph 41 Frosted Yellow Gold / Champagne / Japan

In Context

At 41 mm it is sized to the current mainstream: 40 mm is the median across every watch measured in this catalogue. At 12 mm it is a tall case, and it will catch on a cuff. The case back is closed, so the movement stays out of sight, and the sapphire crystal will resist everything short of deliberate abuse. 50 m covers rain and hand-washing comfortably; it is not a watch to swim in.

The movement winds itself from the motion of your wrist. 70 hours of reserve is enough to set it down on Friday evening and find it still running on Monday. At 28,800 vph the seconds hand advances 8 times a second.

26240BA.GG.1324BA.01 stands on its own in this catalogue — no other reference here shares its base number. It pairs a champagne dial with a yellow gold case. Introduced in 2022. Beyond the time it carries a chronograph.

The 4401 is the integrated flyback chronograph Audemars Piguet introduced with CODE 11.59 in 2019. It was the first chronograph the company designed as a whole rather than as a module on a base. It powers 88 watches in this library. A column wheel controls the chronograph and a vertical clutch engages it, so the seconds hand starts cleanly and the chronograph can run permanently; the flyback resets and restarts on a single press; and the hands reset to zero together, which Audemars Piguet achieved with a patented arrangement of the hammers. The reserve is 70 hours at 28,800 vph with 40 jewels, and the movement is finished for a display back, with a 22-carat gold rotor. It replaced the modular [3126/3840](/calibers/audemars-piguet-ap-3126-3840) and the Piguet-based [2385](/calibers/audemars-piguet-ap-2385), so for the first time every Audemars Piguet chronograph runs one architecture. In the library it sits under 40 [Royal Oak](/brands/audemars-piguet/royal-oak) Chronograph 41 references, the 26240 of 2021, 30 [CODE 11.59](/brands/audemars-piguet/code-11-59) Chronographs and 18 [Royal Oak Offshore](/brands/audemars-piguet/royal-oak-offshore) 43 mm chronographs of 2021. The 41 mm case accounts for 70 references and the 43 mm for 18. Five are limited editions. The [4302](/calibers/audemars-piguet-ap-4302) is the three-hand movement of the same generation, and the glossary defines the [chronograph](/glossary/chronograph).

87 other watches in the library run the Audemars Piguet AP 4401.
