IWC, Portofino Hand-Wound Moon Phase Swiss. C. 2019. For this description, we will use the words of IWC as they have a way of keeping things subtle and elegant in both the written word and watchmaking: For many, it's a dream come true: for the first time ever, IWC has integrated the popular moon phase display in the classic Portofino with its eight-day, hand-wound movement. 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. The watch was found to be running at the time of cataloguing. It has not been tested for timekeeping accuracy and may require adjustment.
