The Portofino Complete Calendar is the first timepiece from IWC with the newly developed complete calendar module. The calendar module consists of 123 individual parts and is mounted on the IWC manufacture calibre 32150. Each of its displays is driven by its own gear train and can be set independently of the others via the crown or via two push-pieces integrated into the side of the case.
The calendar only needs to be corrected manually in months with fewer than 31 days.
