Exclusive First Release! Another heavyweight has arrived! The Cartier Tank True Diamond Small Watch features a case size of 25mm x 20mm, equipped with a genuine Swiss quartz movement. The dial is adorned with 11 pieces of VS1.2 natural diamonds! It has been certified by the authoritative China GTC testing agency, providing a solid guarantee for our diamond watches! .The Cartier Tank series wristwatch was first introduced in 1917, inspired by the parallel facets of the French Renault tank. Its design evolved from the shape of tank tracks into a streamlined steel form, complemented by Roman numeral hour markers, presenting a vintage yet understated elegance. The current version is the top configuration available on the market! Experienced watch enthusiasts can spot the details that set it apart! The authentic version can be completely disassembled and reassembled with original factory parts, using genuine diamond and 904 stainless steel! It is a high-end luxury piece, one of the major works of the year!.What are the differences between the top-tier version, the authentic product, and market replicas? Why is there such a price difference? The answer is simple: any cost-saving measure, from finely crafted components to the movement, can lead to unexpected savings. For instance, movements can range from 10-20 dollars to hundreds or even thousands of dollars. We use imported Swiss quartz movements, while most market replicas focus only on appearance. Therefore, many opt for domestic movements that may look impressive but lack quality in unseen areas and finer details! Every component we use is precisely numbered, ensuring that the case back corresponds to a unique factory code. Moreover, the diamonds we use are genuine and not misleading! We have testing certificates from national authoritative institutions, and we support re-examinations!
