Audemars Piguet Royal Oak Chronograph 26240ST.OO.1320ST.06 41mm Flyback 1:1 Replica Homage

A modern Royal Oak chronograph homage

This APS-crafted timepiece is a high-grade 1:1 homage to the Audemars Piguet Royal Oak Chronograph 26240ST.OO.1320ST.06, bringing the bold, modern Royal Oak design language to your wrist without the constraints of boutique pricing or waiting lists. The 41mm stainless steel case, integrated bracelet and octagonal bezel with exposed screws deliver that unmistakable Royal Oak profile in a package designed for confident daily wear.

Executed in APS’s sought-after four-color Royal Oak configuration, this 41mm flyback chronograph replica offers a rich combination of dial textures, applied markers and sub-dials that catch the light from every angle. From the crisp brushing on the case and bracelet to the polished chamfers that define the edges, every key aesthetic cue is thoughtfully mirrored, giving you a watch that feels substantial, contemporary and luxurious on the wrist.

Authentic reference context & core specs

The authentic Audemars Piguet Royal Oak Chronograph 26240ST.OO.1320ST.06 is part of the current-generation 41mm Royal Oak selfwinding chronograph line, featuring a stainless steel case, integrated steel bracelet and a refined Grande Tapisserie dial paired with sub-dials for chronograph minutes, hours and running seconds. It is powered by AP’s in-house Calibre 4401, an automatic integrated chronograph movement with flyback function, column wheel and vertical clutch architecture, designed to deliver smooth pusher feel and precise timekeeping. The original reference offers central hours and minutes, small seconds, date at approximately 4:30, and a flyback chronograph that allows instant restart of timing with a single press of the reset pusher.

Case dimensions for the genuine 26240ST sit at approximately 41mm in diameter and around 12–13mm in thickness, striking a balance between sporty presence and refined wearability on a range of wrist sizes. The integrated bracelet with AP folding clasp is a defining element of the Royal Oak experience, featuring signature tapering links with a mix of brushed surfaces and polished bevels. Sapphire crystals front and back, applied hour markers with luminescent treatment, and water resistance suitable for daily life round out the original’s specification, making it both a design icon and a capable everyday luxury chronograph.

This APS homage uses those authentic proportions and visual codes as its blueprint: a 41mm stainless steel case, integrated bracelet, octagonal bezel with aligned hexagonal screws, and a Grande Tapisserie-style dial with clear, legible chronograph sub-dials. The dial layout stays faithful to the modern Royal Oak chronograph aesthetic, including a date window at about 4:30 and luminous accents on the hands and indices for low-light readability. While the internal mechanics differ from the in-house AP Calibre 4401, the APS integrated chronograph clone is specifically designed to visually echo its architecture and replicate its core functions, including the flyback feature.

Wear, comfort and style

On the wrist, this 41mm Royal Oak chronograph homage delivers the unmistakable mix of angular presence and slim elegance that has made the Royal Oak a design icon. The integrated bracelet hugs the wrist in a continuous flow of steel links, with a taper that makes the watch feel balanced and secure rather than top-heavy. The approximate 12.4mm thickness keeps the profile relatively sleek for an automatic chronograph, so it will slide under many shirt cuffs while still offering plenty of visual impact when worn with short sleeves.

The four-color Royal Oak dial configuration gives you options that run from classic black or blue to more contemporary grey and silver-toned looks, allowing you to choose a personality that fits your wardrobe. Sub-dials are clearly recessed and framed, adding depth to the Grande Tapisserie pattern and catching light in a way that constantly changes the watch’s character. Whether you pair it with tailoring, smart casual outfits or simple denim and a T-shirt, the strong lines of the octagonal bezel and the meticulous brushing of the case and bracelet instantly elevate your overall look. This is a watch that feels equally legitimate as an everyday companion or as a statement piece for evenings out.

Thanks to its versatile aesthetic and clean steel construction, this APS homage can easily serve as a one-watch collection for many enthusiasts. The flyback chronograph adds a layer of sportiness and practicality, whether you are timing gym intervals, cooking or travel segments. At the same time, the refined dial work, polished bevels and iconic silhouette ensure that it never feels like a purely utilitarian tool—rather, it reads as modern mechanical jewelry with a purposeful edge.

Performance and APS movement details

Inside this Royal Oak Chronograph homage is APS’s fully integrated chronograph clone movement, engineered to mirror the visual layout and functional behavior of AP’s Calibre 4401 while remaining a robust, serviceable engine for everyday wear. The chronograph operates via start, stop and reset pushers that give a positive, mechanical click, and the flyback feature allows you to reset and restart the timing function in one fluid motion. This makes timing multiple intervals more intuitive and satisfying than on a standard start–stop–reset chronograph.

The movement offers central hours and minutes, a running small seconds display, a date window at about 4:30 and chronograph counters for elapsed minutes and hours. It is tuned for stable daily performance with smooth hand motion and minimized mechanical noise, and it is designed to be more reliable and refined than generic modular chronograph replicas often seen at lower price points. While it is not an in-house Swiss calibre and does not carry official chronometer certification, it targets practical accuracy suitable for real-world use, typically within a range that will satisfy most enthusiasts seeking a strong balance between aesthetics, function and cost.

The sapphire caseback allows you to enjoy the visual structure of the APS clone, including a rotor designed to echo the style of the original and a layout that broadly matches the integrated chronograph architecture of its inspiration. Servicing requirements are similar to other mechanical replicas: periodic cleaning, lubrication and regulation every few years will help keep the watch running smoothly. When properly cared for, this movement can deliver many years of satisfying, reliable use as part of a regular rotation.

There is no official connection, endorsement or affiliation with Audemars Piguet or any of its authorized retailers, and no genuine OEM components, serial numbers or manufacturer warranties are included. Logos and design cues are used strictly in an homage context for enthusiasts who understand and appreciate the difference between an authentic high-luxury timepiece and an aftermarket 1:1 replica.
