Full Set Packaging Omega Constellation Series Quartz Women's Watch, Dial Diameter 27mm. The movement uses an original Swiss quartz movement from the same manufacturer. The glass is made of high-strength scratch-resistant German imported sapphire. The dial features pure natural mother-of-pearl, inlaid with 12 VS diamonds, accompanied by a GTC national inspection certificate. Every diamond is genuine, and each watch has been certified by the national inspection bureau to ensure that they are made of authentic materials and real diamonds. At this price, buying diamonds is already worthwhile, not to mention purchasing a watch from this brand. No one would take a loss to counterfeit it. This makes it an absolutely amazing gift. While there are many in the market that also provide certificates, they are just copy certificates worth 20 yuan each, all the same. In contrast, each of our watches has undergone individual testing at the national inspection bureau, ensuring that each one is a genuine diamond watch. Therefore, the inspection numbers on each certificate are completely different, each with a unique number that can be verified at will! Comes with a complete set of official packaging.
