18k gold-filled ROLEX-Rolex Daytona series GTC China National Inspection and Testing Certificate, which can be checked online! The original model of the first-speed time-adjustable watch case, the dial size is 40mm. The thickness is currently the closest to the original ceramic solid outer ring on the market with a speed scale (it uses real ceramic technology that will not scratch or fade, and the texture is the same as the original). The function dial font The overlay printing process is used with the logo on the disk, and it will feel slightly raised when viewed from the side. The background texture of the disk has been filtered and corrected countless times to ensure that it is 100% consistent with the original. The Rolex metal LOGO on it is molded separately, whether it is three-dimensional or three-dimensional. Both the feel and roundness can be compared to the PK original easy-to-read Chroma light luminous display with long-lasting luminous substance. The flat sapphire crystal glass of the watch mirror is scratch-resistant, and the effect will never be ghosted, which is consistent with the original product. The six-digit authentic crown has the same anti-counterfeiting crown. (Pay attention to details) The clasp is made of imported fine steel and polished from 1:1 parts. The inner side is corroded and has a Rolex stamp. The external clasp safety ring is exactly the same as the genuine one.
