The Portofino Hand-Wound Moon Phase Story

The Portofino Hand-Wound Moon Phase in stainless steel 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 silver-plated 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.

Moon phase display

IWC’s moon phase displays are not just aesthetic works of art – they are extremely precise and diverge from the actual phase of the moon by just 1 day in 577.5 years.
