IWC Schaffhausen - Portofino

Portofino Hand-Wound Moon Phase

18 ct 5N gold case, 45.0 mm. Made in Schaffhausen, Switzerland. Model IW516403
Editor's notes
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.
