From LS Factory, the Audemars Piguet Royal Oak Offshore 26420 is a fully upgraded 43mm chronograph. Its ergonomic case (43MM~15.6MM) features larger polished bevels, and the date window is repositioned to the dial’s edge for a bold big - date appearance. The Dandong 7750 movement is modified to mimic Calibre 4401, enhancing stability. Crafted with 316L Japanese steel (brighter than standard 306 steel), it sports a Korean - imported ceramic bezel (blue), a sapphire crystal, and a comfortable fluorine rubber strap (with leather - wrapped cloth options available). The dial is upgraded with a CNC - milled texture and a connected square pattern, delivering a clear, iconic luxury style.
