Details & Specifications
Description
IWC’s Portofino collection was given a recent refresh, and the patriarch of the Portofino watch family is the IWC Portofino Hand Wound 8 Days. What is so impressive is the IWC-manufactured 59210-calibre movement with a generous power reserve of eight days. This is a classic mens watch to last, either in an 18ct gold case with ardoise dial (a striking combination) or stainless steel with a silver-plated or black dial. Affixed to the wrist with a leather strap which completes this elegant IWC timepiece.
This piece dates from 2025 with full box and papers in unworn condition.
