Official description

Presented in a 41-millimetre case size in 18-carat 5N gold or stainless steel, the Portofino Complete Calendar (Ref. 3590) is the first IWC timepiece to feature the newly developed complete calendar module. The subdial at 12 o’clock displays the day of the week and the moon phase, while the date and month are shown at 6 o’clock. The calendar module consists of 69 individual parts. Each display is driven by a separate gear train and can be adjusted independently of the others via the crown or using two two correction buttons integrated into the side of the case. The calendar only needs to be adjusted in months with less than 31 days. On the last day of the month, the date must be manually set to position 31 via the crown. All displays, including the high-precision moon phase display, will then automatically advance by one day around midnight. The calendar module is mounted on top of the IWC-manufactured 32150 calibre. This highly precise and reliable automatic movement features a pawl winding system and a power reserve of 72 hours.
