APS Factory Audemars Piguet Royal Oak 26331 Blue Dial Chronograph Top Replica Watch

In the palace of high-end sports watches, the Audemars Piguet Royal Oak series has always occupied an unshakable position. The model 26331ST.OO.1220ST.01, as a commemorative work launched in 2017 to commemorate the 20th anniversary of the birth of the Royal Oak Chronograph, has become the white moonlight in the hearts of countless watch fans with its 41mm stainless steel case and iconic blue "Tapisserie" plaid dial. The 26331Top Replica Watches version launched by APS Factory this time is based on this classic work. It systematically restores it from the movement to the strap, striving to pay tribute to the original version in every detail. This article will give you an in-depth analysis of the craftsmanship features of this APS factory 26331 blue dial chronograph from multiple dimensions.
1. Authentic traceability: the design code of the 20th anniversary model
To understand the replica level of the top replica watch Royal Oak APS Factory 26331, you first need to understand the ins and outs of the genuine product. In 1997, Audemars Piguet launched the first Royal Oak chronograph, introducing Master Genta's iconic octagonal porthole design into the field of chronograph functions. Exactly 20 years later, to commemorate this milestone, Audemars Piguet released a new Royal Oak chronograph at the 2017 SIHH (Geneva International Haute Horlogerie Show), including the 26331ST blue plate version.
The biggest design change of this generation of 26331 is the disk layout: the three small counters have been changed from the previous blue to silver, forming a sharp "panda eye" contrast with the blue main disk. This design not only improves the clarity of reading, but also visually increases the layering of the disk. At the same time, the watch diameter has been expanded from the early 39mm to 41mm, which is more in line with the contemporary trend of large watch diameters. In addition, the AP logo and brand words have also been enlarged to enhance the visual impact of the dial. It is these detailed features that have become the core points that need to be overcome when the APS factory reproduces them.

2. Movement revolution: Dandong one-piece customized movement, only 11mm thick
The success or failure of a replica watch often depends on the degree of restoration of the movement. The biggest technological breakthrough of APS Factory 26331 is that it is equipped with a Dandong integrated customized movement, which completely bids farewell to the "thick shell" solution of traditional 7750 movement modification.
As we all know, the ordinary version of 26331 on the market mostly uses the 7750 movement and fake plywood, resulting in the thickness of the entire watch reaching 14-15mm, making it as bloated as a "pressure cooker" when worn. The APS factory redesigned the calendar system and main board, increased the number of movement parts by more than 40, and finally controlled the thickness of the entire watch to 11mm, which is consistent with the original version. This millimeter-level restoration makes the watch fit more closely on the wrist when worn, and will not cause the cuff to get stuck when wearing a shirt.
At the functional level, the APS customized movement realizes the full timing function, and the timing second hand returns to zero accurately without deviation. At the same time, the instant calendar jump function is smoother. In terms of automatic hammers, APS Factory uses 22K vacuum electroplated gold automatic hammers, engraved with the AP logo, and optimized edge weights to improve kinetic energy conversion efficiency. For those who are looking for a see-through watch, the real gold plating texture of the automatic hammer and the Geneva corrugated plywood decoration jointly create a visual experience that is similar to the original version.
3. Disk craftsmanship: three-dimensional restoration of the classic “Tapisserie” plaid
The blue “Tapisserie” plaid dial is the most popular visual symbol of the Audemars Piguet Royal Oak, and it is also the core link of the APS factory that spares no expense. APS Factory 26331 uses the original mold opening method to reproduce this classic plaid decoration. Each small square has been carefully calculated. The raised height, spacing and arrangement density of the grid are all consistent with the original version, showing a layered three-dimensional effect under the refraction of light.
In terms of chronograph sub-dials, APS Factory has restored the authentic silver three-eye layout - 30-minute chronograph counter at 3 o'clock, small seconds counter at 6 o'clock, and 12-hour chronograph counter at 9 o'clock.-7. The surface of the sub-disk adopts CD pattern engraving process, with moderate texture depth and natural light and shadow changes. The calendar window is located between the 4 o'clock and 5 o'clock marks, and the edges of the window are chamfered, eliminating the burr problem common in cheap versions.
In terms of hands and scales, APS Factory uses rhodium-plated three-dimensional time scales. The central hour hand, minute hand and chronograph seconds hand are all covered with luminous material to ensure the convenience of reading in dark light environments. It is worth mentioning that the Royal Oak's iconic eight hexagonal screws are still faithfully presented - these screws in the original product are actually made of platinum, and the APS factory also strives to be similar in color and polish.
4. Case and strap: The brushed aesthetics of 904L stainless steel
The case is the carrier of the Royal Oak design language. The combination of its sharp-edged octagonal bezel and hexagonal screws is a classic element instantly recognized by countless watch fans. APS Factory 26331 uses 904L fine steel to make the case. This steel has higher corrosion resistance and better polishing performance than 316L. It is also a material widely used by high-end brands such as Rolex.
In terms of polishing process, the APS factory follows the original principle of "combination of polishing and drawing" - the edge of the bezel is highly polished, while the front of the case is finely brushed vertically.-2. This contrasting polishing process not only improves the visual layering, but more importantly, the brushed surface can effectively cover up the subtle scratches caused by daily wear. This is one of the reasons why genuine wearers report that "it stays new after being worn for a long time".
As for the strap, APS Factory uses genuine molded integrated stainless steel straps. The link structure is ergonomic and fits snugly and comfortably.-2. Each strap is assembled individually, which avoids the "overall stiffness" problem common in lower versions. The opening and closing damping of the clasp has been carefully adjusted, and it closes crisply without the "spring sound" of cheap watches.
5. The charm of blue disk: a visual feast of changing light and shadow
Among the many Royal Oak watches, the blue dial is always the most popular choice. The genuine 26331 blue plate even requires a tie-in to purchase, which shows its scarcity and popularity. The charm of this touch of blue lies in its "fickle" quality - under different lighting conditions, it will show rich layers from deep navy blue to bright electric blue.
The APS factory invests a lot of energy in blue adjustment and strives to restore the color performance of the original product. According to market feedback, the color difference control of the blue disk of the APS version has reached more than 95%, making it difficult to distinguish it from the genuine product under natural light. Coupled with the three-dimensional texture of the "Tapisserie" plaid, the disk will show subtle changes in light and dark at different angles. This is a visual depth that ordinary printed disks cannot achieve.
For the wearer, the blue dial also has a practical advantage: compared to black or white, blue is more low-key and restrained in daily wear. Many authentic wearers said that the Royal Oak blue dial can make everyone think "this watch is good-looking" in an environment that does not know much about watches, but it will not make people feel as high-profile as Rolex. This "low-key sense of luxury" is the unique charm of the 26331 blue plate.
6. Wearing experience: See the details in detail
An excellent watch must ultimately be tested by the wearing experience. APS Factory 26331 has made many optimizations in terms of ergonomics. First of all, the 41mm watch diameter is suitable for most men's wrists. It will neither appear too large to press on the hand, nor too small to lack a sense of presence. Secondly, the thickness of 11mm is well controlled, so even when worn with a formal shirt, the watch head can easily slide into the cuff.
The curvature of the lugs has been optimized to naturally fit the curve of the wrist when worn, avoiding the common problem of "warped lugs" in traditional replica watches. The weight of the entire watch is controlled at about 158g (including the strap), which is only 6g different from the original version. The center of gravity is reasonably distributed and there will be no "top-heavy" imbalance. Of course, there are also reports from genuine wearers that the Royal Oak watch strap occasionally gets caught in the hair on their hands. This is a feature of the watch strap design itself, not a workmanship problem. Those who mind can adjust the wearing position appropriately.
In terms of waterproof performance, APS Factory 26331 has reached a 50-meter domestic waterproof level, which is enough to cope with daily hand washing, rain and other scenes, but it is not recommended to wear it for swimming or bathing.
