The Portofino Hand-Wound Moon Phase in 18-carat 5N gold pays homage to the first Portofino from 1984, which also had a moon phase display. It is powered by the hand-wound 59800-calibre movement, which has a power reserve of 8 days when fully wound. The slate-coloured dial with moon phase display, date, small seconds and power reserve display is simple and balanced. The see-through sapphire-glass back provides a view of the 8-day movement and the various decorations on the plates and bridges. The dark brown strap is made from alligator leather by the Italian company Santoni.
Calibre Family 59000
Watch connoisseurs look forward to the weekly ritual of manually winding IWC-manufactured 59000-calibre-family movements to ensure that they run precisely for 8 days.
