The Portofino Hand-Wound Pure Classic (Ref. IW511101/IW511102) dispenses with any form of embellishment and was designed, purely and simply, to show the time of day. It also radiates composure and an undiluted aesthetic. It has a traditional, arched-edge front glass, which not only makes the 43.5-millimetre diameter of this harmonious model seem smaller than it actually is, but also gives the watch a classic, balanced appearance.

The Portofino Hand-Wound Pure Classic is available in an unlimited edition exclusively at selected IWC boutiques.
