The engraving on the crown and pushers is precise, showcasing superb craftsmanship! The satin-finished ceramic clasp is meticulously polished inside and out, with the pin's tip meticulously chamfered to perfectly replicate the details of the genuine article! .The movement uses a precise Hangzhou 7 series modified to Blancpain's own Cal.1315 movement, with the color of the bridge's jewel bearings matching the original, ensuring a pure hue that eliminates any initial doubts about authenticity! The integrated bridge not only enhances its visual similarity to the original but also provides better protection for the movement, ensuring greater stability! After grinding, the bridge undergoes chamfering to prevent any copper shavings from falling into the movement, which could cause it to stop unexpectedly.The size of the date on the dial matches the original perfectly, and it features 100% Swiss-imported C3 luminescence that rivals the brightness and longevity of genuine products! The watch is factory-tested for 100% water resistance with a thorough three-stage waterproof test.
