Full Set Packaging Omega Constellation Series Quartz Women's Watch, Dial Diameter 27mm. The movement features an original Swiss quartz movement sourced from the same origin. The glass is made of high-strength, scratch-resistant German-imported sapphire. The dial is made of pure natural mother-of-pearl and is inlaid with 12 pieces of VS-grade diamonds, certified by the GTC National Inspection Bureau. Every diamond is a genuine diamond, and each watch has been certified by the national inspection bureau to ensure that they are all made with authentic materials and genuine diamonds. At this price, buying diamonds is already worthwhile, not to mention purchasing a watch from this brand no one would engage in a losing business by counterfeiting it. This makes it an absolutely fantastic gift. While many in the market also provide certificates, they are merely copied certificates costing 20 yuan each, all identical. In contrast, each of our watches undergoes individual testing at the national inspection bureau, guaranteeing that every piece is made with authentic materials and genuine diamonds. Therefore, each certificate has a unique inspection number, all independently numbered, and can be freely verified! Comes with a complete set of official packaging.
