As one of the “three major steel kings”, the Royal Oak 15400 blue-faced model launched by APS factory, with the breakthrough of highly restoring the iconic octagonal porthole design and ultra-thin technology, completely solved the previous problem of “fake at a glance” in terms of thickness with 9.8mm, which is highly consistent with the genuine product.
9.8mm ultra-thin case
Previously, the common Aibi Royal Oak replica watches in the industry used the West Railway City 9015 modified splint movement, and the thickness of the whole watch was generally 11mm, which was very different from the original. With the breakthrough of cloning technology, the APS factory took the lead in launching the upgraded version of the V3 equipped with Dandong 3120 all-in-one movement, which controlled the thickness of the whole watch at 9.8mm (error ±0.1mm), truly achieving the ultra-thin texture.
Dandong 3120 automatic winding all-in-one movement actual test
The Dandong 3120 automatic winding all-in-one movement equipped with the APS factory Top-quality Audemars Piguet Royal Oak replica watch can reach 65-68 hours of actual movement in the full chain state. The accuracy when walking is high, and the daily wearing error is stable at ±5-8 seconds/day after the appearance adjustment, and the error of normal wearing for 2-5 years is still very stable. The upper chain feels heavy and smooth, without the common looseness and graininess of cheap movements. There is almost no noise, and you can only hear the slight sound of mechanical operation when it is close to the ear in a quiet environment.
Complete and smooth restoration of genuine functions
The calendar adopts a slow jump design consistent with the genuine product, and the jump is completed between 11:30 and 12:30 at night. The position of the pendulum wheel is at 7 o’clock, which is consistent with the original version. PVD electroplated metal automatic gyro, the plating layer is about 5-10 microns, and it is not easy to fade after long-term wear. It is extremely difficult for non-professionals to see the difference between it and the genuine product, which effectively reduces the possibility of “fake at a glance” of the back.
1:1 Restore the details of the genuine appearance
The synchronous genuine case adopts a four-piece structure, the front is finely brushed, all the bevels are mirror polished, and the champing is also very meticulous. The “Grande Tapisserie” plaid on the dial is engraved with 3D laser, and the texture is deep and three-dimensional. The word “Audemars Piguet” adopts a raised printing process, which looks very three-dimensional and does not want the flat feeling of the cheap version. The strap is equipped with 316L stainless steel and synchronous movable head grain design. It is also very comfortable to wear for a long time and will not press your hands.
