IWC Schaffhausen Iw344602 Portofino Perpetual Calendar

Owners widely praise the IWC Schaffhausen Iw344602 Portofino Perpetual Calendar for its elegant, clean dial, tasteful hands, and smart functionality. The 40mm case size and 12.7mm thickness are generally considered well-proportioned, though one owner found it slightly feminine and disliked the lug design and factory strap. Reviewers highlight the Kurt Klaus perpetual calendar module as foolproof and recognizing months and leap years until 2100, utilizing the IWC Calibre 82650 with a 60-hour power reserve. Some owners note that the subdials require advancing the crown to set and cannot be set backward, and one heard of potential malfunctions after leap days. On balance, owners and reviewers rate the IWC Schaffhausen Iw344602 Portofino Perpetual Calendar highly for its sophisticated perpetual calendar complication and refined wearability.
