High-end genuine products, exclusive debut! Another heavyweight has arrived! The Cartier Tank True Diamond watch features a case size of 25mm x 20mm, an original Swiss quartz movement, and is adorned with 24 pieces of VS1.7 natural diamonds! It has been officially certified by the authoritative China GTC testing agency, providing solid assurance for our diamond watch!.The Cartier Tank series wristwatch was first introduced in 1917, with its design concept inspired by the parallel facets of the French Renault tank. The shape evolved from tank tracks into a strip steel design, complemented by Roman numeral hour markers, exuding a retro charm without losing its understated elegance. The current version is the top configuration on the market! Some professional watch enthusiasts can spot the differences in details! The genuine product is completely disassembled for mold-making and uses original factory movement and genuine diamond 904 stainless steel material! It is high-end and luxurious, making it one of the significant masterpieces of this year!.What are the differences between the top-tier version and the genuine or market products, and why is there such a price disparity? The answer is simple: any omission in the meticulous craftsmanship of components or movements will save costs in ways you might not expect. For instance, movements can range from 10-20 yuan to hundreds or even thousands of yuan. We use imported Swiss quartz movements, while most market replicas focus solely on outward appearances. Therefore, from this perspective, opting for domestic movements that only look good is common. This is where unseen details come into play! Each of our components has precise specifications, ensuring that the case back corresponds to a unique factory code for every watch! Furthermore, the diamonds we use are not just for show; they come with certification from national authoritative testing institutions! Re-testing is supported!
