1. Case: The case is manufactured by a large Taiwanese manufacturer, 3D. It is modeled according to the specifications of the genuine watch, ensuring that all aspects of the case match those of the original watch (therefore, most components can be replaced with those from the genuine watch). All parts are processed using high-precision German CNC technology, resulting in excellent fit between different components! 2. Backcover: This is the only watch on the market that uses a solid inner cover identical to that of the original watch. The movement is placed and secured using CNC processing techniques. The manufacturing process is intricate and sophisticated. (Ordinary products on the market use very low-quality plastic covers, so this watch feels very light in hand.) 3. Movement: It features a high-power Swiss quartz movement, along with a special plate from Cartier. The movement operates accurately, with no need for repairs! 4. Dial: The dial is made by CNC machining, with a silver finish. The scales are of a track-style design, and the Roman numerals are displayed in a three-level pattern. The effect of sunlight on the dial is beautiful and clear. 5. Crystal: The crystal is made of French sapphire glass that has been treated to have high transparency. It appears almost invisible. 6. Leather strap & clasp: The leather used is Italian calfskin. The surface is treated with crocodile pattern, and it is polished with agate stones. The appearance and feel are no less good than those of ordinary crocodile leather on the market. The inner lining is made from the same material as that used in Cartier watches. It fits well and feels comfortable. Combined with the signature Cartier clasp, which is modeled after the 1 and 1 movements, it creates a perfect combination. 7. Hands: The hands are made of steel that has been quenched. The rotation angle creates a gradual effect, making the watch look very dynamic. 8. Crown: The distinctive crown is decorated with circular beads created using a five-axis machine. These beads are carefully polished, and their shape is smooth and round. At the top of the crown, there is a blue gemstone polished from natural stones. Ordinary products on the market use glue or synthetic materials, resulting in a dull color. However, this product has a beautiful shine when exposed to light. 9. Finish: The case body has a polished finish on its front side. The scratches are smooth and clear. The edges of the case and sides are also polished, giving a clear and distinct appearance. The band is treated with a mirror-like finish, and the signature screws are visible, enhancing the texture. 10. Packaging: The tag, warranty card, and code on the bottom cover are all consistent. This watch can be worn with formal business attire or sportswear. Cartier’s enduring reputation and timeless design make it an excellent choice for personal use or as a gift to friends and family!!
