Brand and reference history

Audemars Piguet occupies a unique position within Swiss haute horlogerie. Founded in Le Brassus in 1875 by Jules Louis Audemars and Edward Auguste Piguet, the manufacture built its reputation on technically demanding complications, refined finishing and an independent approach to watch design. The Royal Oak, launched in 1972, transformed expectations of what a luxury watch could be by placing a high-end mechanical movement inside a boldly angular steel case with an integrated bracelet.

Reference 26240ST.OO.1320ST.04 belongs to the Royal Oak Chronograph generation created for the collection’s 50th anniversary. Its commemorative significance is expressed through the model’s carefully evolved proportions, the anniversary-era execution of its dial and the updated mechanical platform beneath the caseback. Rather than treating the Royal Oak as a historical replica, Audemars Piguet has developed the concept for contemporary wear while preserving the essential elements that make the design immediately recognisable.

Dial, hands and design detail

The olive-toned dial is the visual centre of this Royal Oak Chronograph. Its colour is nuanced rather than loudly metallic, moving between green, olive and darker shaded tones as the light changes. That restrained character gives the watch versatility: it retains the presence expected of a luxury sports chronograph while working equally well with tailored clothing or more relaxed weekend wear.

Its Grande Tapisserie pattern adds depth across the dial through a precise field of raised geometric squares. The three sub-dials at 3, 6 and 9 o’clock are colour-matched to the main dial, creating a cohesive appearance while providing the chronograph’s elapsed-time displays. Applied hour markers and hands are treated for enhanced visibility in low light, and the clean, highly structured layout helps the watch remain legible despite the information-rich nature of a chronograph.

Small details reinforce the Royal Oak identity. The octagonal bezel, exposed screw heads and alternating polished and brushed surfaces give the watch its characteristic architectural rhythm. The result is not decorative excess; every element contributes to the tension between precision, utility and luxury that has made the Royal Oak such a lasting design.

Case, bracelet and wearability

The case is made from stainless steel, a material that suits the Royal Oak’s original design philosophy particularly well. Steel gives the watch a reassuringly substantial feel while allowing the sharp geometry of the case and bezel to remain the focus. Brushed surfaces provide a technical, satin-like foundation, while polished chamfers and edges catch the light around the bezel and case profile.

The integrated stainless-steel bracelet is central to the watch’s identity. Instead of appearing as a separate component attached to conventional lugs, it flows directly from the case, creating a continuous line around the wrist. Its articulated construction allows the bracelet to follow the wrist naturally, while the combination of satin finishing and polished accents echoes the case treatment. This is one of the reasons the Royal Oak feels distinctive even before its dial is noticed.

The folding clasp keeps the bracelet secure and preserves the clean external appearance. As with any watch featuring complex brushed and polished surfaces, careful handling is important: sharp edges and mirror-finished facets can show marks more readily than a simple fully brushed case. Used thoughtfully, however, the steel construction is robust enough for regular rotation and everyday luxury-sports wear.

Movement and technical specification

Reference 26240ST.OO.1320ST.04 is powered by Audemars Piguet’s self-winding chronograph calibre 4401. This integrated automatic movement was developed for the modern Royal Oak Chronograph and incorporates a column wheel with a vertical clutch. In practical terms, that architecture supports precise chronograph operation and helps the start, stop and reset actions feel crisp and controlled.

The movement also includes a flyback function, allowing the chronograph to be reset and immediately restarted with a single action. This is a technically useful feature with roots in timing applications, and it adds a satisfying level of mechanical sophistication to a watch that is already more than a simple time-only instrument. The display provides central hours and minutes, running seconds, chronograph seconds and elapsed-minute and hour indications through the three subsidiary registers.

Visible through the sapphire caseback, the movement is finished in keeping with Audemars Piguet’s standards, with decorative details intended to reward close inspection. The rotor and bridges contribute to the visual appeal of the watch from both sides, while the automatic winding system makes it practical for regular use. The specified reference is a stainless-steel automatic chronograph with an olive-toned Grande Tapisserie dial, luminous hands and hour markers, and an integrated stainless-steel bracelet.

Sizing and how it wears

The Royal Oak Chronograph has a confident wrist presence, but its integrated construction helps it wear more cohesively than its headline dimensions might suggest. The case sits low enough to remain controlled under a cuff, while the broad bracelet distributes the weight across the wrist rather than concentrating it at the case. This balance is particularly important with a chronograph, where the additional registers and mechanical architecture naturally give the watch a more substantial profile.

On the wrist, the octagonal case creates a strong horizontal visual line, with the bracelet extending that shape rather than interrupting it. The olive dial softens the technical nature of the steel and adds warmth, making the watch less stark than a monochrome black or silver-dialed alternative. It is suited to buyers who want a watch with presence and individuality, but who also expect the refinement required of a high-end Swiss sports model.

As with all integrated-bracelet watches, accurate bracelet adjustment is important for comfort and proportion. A correctly fitted bracelet allows the case to remain centred and lets the articulated links move naturally. The watch is substantial enough to feel special, yet sufficiently versatile to become a regular part of a considered collection.

Collectability and market value

The Royal Oak is one of the foundational designs of contemporary luxury watch collecting, and anniversary references benefit from that broader cultural and horological importance. The 50th Anniversary editions are especially notable because they connect the current generation with five decades of the Royal Oak story without abandoning the collection’s modern engineering. The combination of a famous design, a technically advanced chronograph movement and a distinctive olive-toned dial gives this reference several points of interest for collectors.

Market value in this segment is shaped by more than the material specification alone. Condition, completeness, service history, original accessories and the quality of the dial and case finishing can all influence desirability. The limited visual language of an olive Grande Tapisserie dial can also appeal to collectors seeking something more individual than a conventional black or blue configuration. At the stated price of £54,995.00, this example occupies the serious luxury-watch category and should be assessed on its reference, condition and supporting documentation rather than on appearance alone.

For buyers comparing complications and styles, our wider collection of chronograph watches provides useful context. A Royal Oak Chronograph is not simply a timepiece with additional sub-dials; it is an integrated design in which the case, bracelet, dial and movement have been conceived as a single proposition.

Authenticity, condition and servicing

Authenticity is essential when purchasing an Audemars Piguet of this level. Reference details, dial configuration, case construction, movement architecture and finishing should all correspond to the stated model. A proper assessment looks beyond the logo and general appearance, considering the relationship between the case, bracelet, clasp, chronograph controls and movement. This is particularly important with highly recognisable sports watches, where originality and correct specification have a direct bearing on long-term value.

Condition should be judged with equal care. The crisp edges of a Royal Oak case and the transition between brushed and polished surfaces are important components of its design. Over-polishing can soften those lines, while careless refinishing may reduce the definition that gives the watch its character. We recommend reviewing the watch in detail for signs of wear, service intervention and any replacement components, with the available supporting information considered alongside the visual inspection.

Mechanical watches benefit from sensible ongoing care. The chronograph should be operated deliberately, the crown secured correctly and the watch protected from unnecessary shocks, magnetic fields and moisture. Servicing should be entrusted to an appropriately qualified specialist, with the interval determined by use, performance and the manufacturer’s recommendations rather than by an arbitrary calendar date.
