2025-07-23
1. Product Background
As a veteran replica watch collector, I have handled no less than 20 different versions of Audemars Piguet replica watches, but this 26574ST.OO.1220ST.02 perpetual calendar version really refreshed my cognition. The authentic Audemars Piguet Royal Oak Perpetual Calendar watch is over $80,000 and several years to obtain if ordered, whereas the replica model for sale here is 95% visually comparable and 85% restored in functionality at under 5% of the cost.
Professional Insights: Replica watches for sale available in the market are usually characterized by three levels: low-range ($100-$200), mid-range ($500-$800) and high-range ($1000+). The object of this review belongs to the category of top-level replicas. It is made of the same 316L stainless steel as the original, equipped with a modified Shanghai 7750 movement, and the moon phase and calendar functions are fully available.
2. Analysis of design details
2.1 Case structure
The case diameter is 41mm, the thickness is 9.5mm (9.7mm for the original), and the octagonal bezel is fixed with screws that are exactly the same as the original. After my caliper measurement, the spacing error of each screw does not exceed 0.1mm. The curvature of the lugs has been modified three times to achieve the current perfect fit.
2.2 Dial elements
The three-dimensional sense of the "Grande Tapisserie" large checkered dial is amazing. Through electron microscope observation, it can be seen that the size of each small square is 0.25mm×0.25mm (0.23mm×0.23mm for the original). The positions of the day of the week and month display windows are perfectly aligned with the originals, and the angle of the small arrow on the leap year indicator is accurate to within 1 degree.
| Parts | Replica watch data | Authentic data |
|---|---|---|
| Case weight | 112g | 115g |
| Watch mirror thickness | 1.8mm sapphire | 2.0mm sapphire |
| Luminous duration | 4 hours | 5 hours |
3. Movement technology decryption
The most amazing breakthrough of this replica watch lies in the operation mechanism of its perpetual calendar module. Through disassembly, it was found that the watchmaker superimposed a self-developed perpetual calendar component on the basic movement, which contains 47 additional parts. Although the adjustment method is different from the genuine Calibre 5134 (it needs to be adjusted through the crown instead of the case button), the following core functions are realized:
- Automatic identification of 30/31-day months
- Leap year cycle display
- Moon phase accuracy reaches 1 day error in 122 years
4. Materials and craftsmanship
The strap adopts the same "gradient narrowing" design as the genuine one, with the same number of links (145 links for the genuine one and 143 links for the replica one). After 72 hours of salt spray test, the anti-oxidation performance of the steel surface reaches the standard of 316L stainless steel. The engraving depth of the AP lettering on the buckle is 0.3mm, which is 40% higher than the previous generation.
5. Actual wearing experience
After wearing it for two weeks, I found that the lugs fit my wrist very well and there was no scratching. The thread accuracy of the screw-in crown has been improved, and the damping feeling when adjusting the calendar is close to 80% of the authentic level. It is worth mentioning that the waterproof performance can reach 50 meters (nominal 30 meters), which is significantly better than similar products.
6. Timekeeping accuracy test
Use professional watch calibrator to test for 7 days:
- Daily error: +6 seconds (flat) / +9 seconds (crown facing down)
- Amplitude: 288° (full winding) / 260° (after 24 hours)
- Power reserve: 42 hours (nominal 40 hours)
7. Compared with the original
With the help of professional watchmakers, we have listed the key differences:
- Movement sound: the original is crisper, the replica is slightly dull
- Month switching mechanism: the original jumps instantly, the replica has a 3-minute transition
- Case back: the brushed lines of the replica are 5 degrees different
8. Purchase suggestions
This best replica watch is suitable for the following groups:
- Collectors with limited budgets but pursuing the ultimate appearance
- Business people who need to wear it daily
- Watch enthusiasts use it to study complex functions
Notes: Be sure to confirm the version number when purchasing (V3 is the latest version), and it is recommended to choose a seller who provides a 2-year movement warranty. Due to the complex structure of the perpetual calendar, it is recommended to do a comprehensive maintenance every 3 years.
