Owners and reviewers widely praise the IWC Schaffhausen Iw516401 Portofino Hand Wound Moon Phase for its elegant design, beautiful finishing, and impressive moon phase complication. The eight-day power reserve from the manual-winding 59800 movement is a frequently highlighted feature, with its neat finishing visible through the caseback. However, the 45mm case size is a recurring point of discussion, with some finding it too large for smaller wrists, though others note its comfortable wearability despite the dimensions. Overall, owners and reviewers rate the IWC Schaffhausen Iw516401 Portofino Hand Wound Moon Phase highly for its sophisticated complication and substantial power reserve, with the primary caveat being its considerable size.
