Dandong 3135 movement: The pursuit of extreme detail is the essence of HP Factory's craftsmanship, and creating the highest cost-performance ratio in the market is HP Factory's sincerity! The Rolex 40MM Submariner top version, made of 904 steel, features exquisite polishing, achieving perfection in every detail for a comfortable fit. The bezel matches the genuine product, while the sapphire crystal is paired with a coated date magnifier. Swiss luminous material provides exceptional night visibility, akin to the original. The crystal showcases a hidden anti-counterfeit crown logo with six positions, and the original folding clasp features unique inner engravings exclusive to the genuine Submariner series. The double inner shadow font utilizes the integrated Dandong 3135 movement. Welcome to appreciate!
