AP Royal Oak model 15550ST - 15451ST has made a stunning debut: the removal of excess parts from the movement plate has made it even more skeletonized, achieving the pinnacle of steel watches - a powerful interpretation of the reigning king of steel! .Five major highlights: .1. Authentic disassembly and mold creation, with a size of 37mm consistent with the genuine product! .2. Perfectly replicates every detail of the genuine watch case, showcasing the distinct and masculine character of the original with sharp angles and boldness.3. The craftsmanship of the steel bracelet is impeccable, surpassing any steel bracelets available in the market; the tension of the cushion link connecting the bracelet and the watch head is identical to that of the genuine product.4. The automatic rotor pays tribute to the original, being the only version in the market that matches the color of the original, while other market versions tend to be slightly red; the engraving of the AP logo on it is unique.5. Featuring a 9015 imported movement modified to the AP CAL3120, it is more stable, superior, and authentic. The dial's biscuit texture is three-dimensional and full-bodied, exuding vitality! This is certainly not an ordinary experience from a small factory; it is exquisitely crafted, providing a distinct and premium experience! It is truly a masterpiece!
