The IWC Portuguese Annual Calendar replica is equipped with an Asia IWC 52850 automatic movement, ZF disassembled all 326 components of original movement, after lots of trials of data analysis, the clone movement looks 90% the same as original 52850, besides, its adjusting method and winding feel are 100% the same as original. Because this IWC Portuguese watch has a see-through case back, so on the replica movement, ZF factory needs to work hard on the movement decoration. The following are photos of four Portuguese Annual Calendar watches.
