Standing far above ordinary street-grade copies, the Audemars Piguet Royal Oak Offshore Chronograph 44MM is a flagship 1:1 Super Clone release from APS Factory / ZF Factory. With its 44MM case in solid 316L stainless steel, double anti-reflective sapphire crystal, and a calibrated 1:1 Swiss Super Clone automatic movement running at 28,800 vph (4Hz), it delivers a smooth sweeping seconds hand, quiet bidirectional winding, and stable daily accuracy right out of the box.

Dial Details, Sapphire Clarity & Bracelet Comfort

From the smooth threading of the winding crown to the crisp snap of the clasp on its matching bracelet and precision-machined folding clasp, the Audemars Piguet Royal Oak Offshore Chronograph 44MM is built for real-world wear. Its 44MM solid 316L stainless steel case is sealed with rubber O-ring gaskets and pressure-tested before leaving our studio.
