ZF Presents the IWC Portuguese 150th Anniversary Edition – Back Transparent Commemorative Chronograph, Perfectly Recreated with Stunning Precision

Movement: Equipped with a modified Dan Dong 7750 movement, meticulously re-engineered to replicate the original CAL.69355 caliber. Full alignment in thickness, dimensional data, layout, balance wheel position, and functional operation—flawless in every detail. Case: The watch measures 40mm x 13.1mm, identical to the genuine piece. With the same proportions and superb finish, its ergonomic design features streamlined lugs that conform comfortably to the wrist for exceptional wearing comfort. Matching the authentic model: The dial employs enamel painting techniques, while the markers use layered printing technology, achieving an overall texture rivaling that of the original.
