IWC Schaffhausen Iw516401 Portofino Hand Wound Moon Phase

Owners and reviewers widely praise the IWC Schaffhausen Iw516401 Portofino Hand Wound Moon Phase for its elegant design, impressive moon phase complication, and practical eight-day power reserve from the manual-winding 59800 movement. The expansive slate grey dial is noted for accommodating multiple displays without appearing cluttered, and the movement finishing visible through the caseback is a highlight. However, the 45mm case size is a recurring point of discussion, with some finding it too large for smaller wrists, though one reviewer found it surprisingly comfortable despite its dimensions. Overall, owners and reviewers rate the IWC Schaffhausen Iw516401 Portofino Hand Wound Moon Phase highly for its sophisticated complications and substantial power reserve, with the primary caveat being its significant case diameter.
