IWC Portofino Perpetual Calendar (Ref.IW344602) Watch

Portofino Perpetual Calendar (Ref.IW344602) features an 18-carat 5N gold case, a silver-plated dial, gold-plated hands, solid gold appliques, and a taupe calfskin strap. 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.
