1. Case: The case is manufactured by a major Taiwanese manufacturer, 3D. It is scanned and molded to ensure full compatibility with the genuine model; 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 components! 2. movement: The inner case uses a solid cover identical to that of the original watch. The movement is housed in a carefully designed position and secured properly. The manufacturing process is complex and precise. In contrast, ordinary watches use very low-quality plastic covers, making them feel very light in hand. 3. Movement: A high-performance Swiss quartz movement combined with a Calatrava-grade plate. It operates accurately, requiring no repairs! 4. Dial: A dial made by CNC machining, with three levels of silver coating. The scale is arranged in a track-like format, and the Roman numerals are three-dimensional. The effect of sunlight reflections on the dial is beautiful and clear. 5. Mirror surface: Made from French sapphire crystal glass that has been treated to have high transparency; it appears almost invisible. 6. Leather strap & clasp: The leather used is Italian cowhide, with a pattern of crocodile skin. The surface is polished with agate stones. The appearance and feel are no less good than those of ordinary crocodile leather available on the market. The interior lining is made of the same material as that used in the original Calatrava watches, providing comfortable wear. Together with the signature Calatrava clasp, which is based on the 1/1 models, they complement each other perfectly. 7. Hands: The hands are made of steel that has been quenched, allowing for a gradual change in rotation angle, making them very dynamic. 8. Crown: The distinctive crown features circular beads created by a five-axis machine. These beads are carefully polished, resulting in a clear and smooth shape. At the top of the crown, there is a blue gemstone polished from original stones (ordinary watches use plastic or synthetic materials; their colors are dull and lack transparency). Under light, these gems reflect a beautiful shine. 9. Finish: The case body has a fine finishing process on its front side. The scratches on the case surface are smooth and clear. The edges of the case and sides are also polished, giving a clear and distinct appearance. The band is treated to have a mirror-like finish, and the signature screws add a distinctive touch to the overall design. 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. Calatrava’s enduring reputation and timeless design make it an excellent choice for personal use or as a gift to friends and family!!
