After ZF 15400, it will go one step further! It will fight against Audemars Piguet Royal Oak 15500, the pinnacle of steel watches on the market, and defend the title of "steel" king with strength! [6 exquisite features] 1. The original product is disassembled and opened, and the size is 41X10.4 mm, which is the same as the original product! 2. Every detail of the original watch case is perfectly restored, showing the masculine temperament of the original product's "clear edges, firmness and courage". 3. The workmanship of the steel band is impeccable, which is better than any other steel band watch on the market. The tightness of the "buffer band" connecting the steel band head and the watch head is exactly the same as the original. 4. The automatic rotor pays tribute to the original, and it is the only version on the market that has the same color as the original (the general versions on the market are reddish), and the engraving of the AP family emblem on it is unique. 5. Breaking the concept of splint, using the 9015 movement to modify the Audemars Piguet CAL.4302 all-in-one machine! More stable, better, and more realistic. 6. The "biscuit texture" of the dial is three-dimensional and full, and energetic! It is definitely not the lost soul of ordinary small factories. Experience the exquisite feeling! ZF products must be high-quality!
