The latest model of Audemars Piguet from HBF, ceramic bezel version. The Royal Oak Offshore limited edition multi-functional chronograph mechanical watch, with a diameter of 44MM and a thickness of 17MM. The bezel is made of imported ceramic, consistent with the original. The crown is made of hexagonal ceramic material, with a brushed finish on the top. The movement is more imposing when exposed through the transparent back cover. The grey-black automatic rotor has a strong sense of layering, and the gemstones are inlaid on the surface of the movement. The 7750 movement has been modified to Calibre 4401 automatic chronograph mechanical movement. The crystal is made of imported sapphire glass. The case is made of imported 316L stainless steel. The strap is made of imported fluororubber, with an original pin buckle. A must-have for tough guys. After multiple grinding and sandblasting processes, the octagonal bezel of AP is expressed with distinct lines. Highly recommended for entry-level Audemars Piguet watches!
