The IWC Portofino Vintage Hand-Wound Moon Phase (Reference IW544803) is a luxury timepiece from the IWC Vintage Collection, originally launched in 2008 to celebrate the brand's 140th anniversary. This model pays homage to the legendary "giant" Portofino (Ref. 5251) from 1984, retaining its oversized, pocket-watch-inspired proportions.
