Audemars Piguet Royal Oak Chronograph 26240 Series

Product Description

The Audemars Piguet Royal Oak Chronograph 26240 Series was introduced in 2022 to mark the 50th anniversary of the Royal Oak. Representing a new generation of the 41 mm Royal Oak Selfwinding Chronograph, the collection preserves the unmistakable design language established by the Royal Oak in 1972 while incorporating a modern flyback chronograph movement into its iconic integrated architecture.

As an important generation of the Royal Oak Selfwinding Chronograph, the 26240 maintains the established proportions and distinctive profile of the collection while introducing refinements to the dial details, ergonomics and overall visual balance. The octagonal bezel, exposed hexagonal screws, Grande Tapisserie dial and integrated construction create the unmistakable Royal Oak identity, while three chronograph counters emphasize its sporting and technical character.

The 26240 Series includes different materials and dial configurations depending on the complete reference number. Despite these variations, the collection is fundamentally defined by classic Royal Oak design, sophisticated finishing and the Calibre 4401 selfwinding flyback chronograph movement.

Product Features

• Iconic Royal Oak Chronograph Design

The 26240 Series retains the signature octagonal bezel, eight exposed hexagonal screws and integrated construction of the Royal Oak while incorporating three chronograph counters into its distinctive dial architecture. The combination of geometric design and chronograph functionality gives the watch a pronounced sporting character without compromising its recognizable Royal Oak identity.

• 41 mm Case Proportions

The watch features a 41 mm case measuring approximately 12.4 mm in thickness. These dimensions provide the characteristic wrist presence of the Royal Oak while accommodating the automatic chronograph mechanism and maintaining the architectural profile of the collection.

• Grande Tapisserie Dial

The dial features the signature Grande Tapisserie pattern associated with the Royal Oak. Its dimensional structure creates changing reflections according to light and viewing angle. Different 26240 references feature different dial colors and detailing, providing varied interpretations of the same fundamental design.

• Three-Counter Chronograph Layout and Date Display

The dial incorporates three functional subdials dedicated to chronograph and running indications, together with a date display. Applied hour markers and characteristic Royal Oak hands maintain the visual identity and clear readability associated with the collection.

• Calibre 4401 Flyback Chronograph Movement

The 26240 Series is powered by the Audemars Piguet Calibre 4401, an integrated selfwinding flyback chronograph movement featuring a column wheel and vertical clutch. The flyback function allows the running chronograph to be reset and immediately restarted with a single operation. The movement operates at 4 Hz, or 28,800 vibrations per hour, and provides approximately 70 hours of power reserve.

• Brushed and Polished Finishing

The distinctive visual character of the Royal Oak is enhanced by sophisticated surface finishing. Alternating brushed and polished surfaces emphasize the geometry of the octagonal bezel, case and integrated bracelet. Their interaction with light creates the refined reflections that have become an essential part of the Royal Oak aesthetic.
