IWC presents the Portofino Complete Calendar, the first timepiece to feature the new complete calendar module developed by the Schaffhausen based luxury watch manufacture.
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 sub-dial 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.
IWC Cal. 32150 with Complete Calendar Module
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 correction buttons integrated into the side of the case.
The complete 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. The IWC Portofino Complete Calendar is presently available in two versions.
Versions
One version (Ref. IW359002) features an 18-carat 5N gold case, a silver-plated dial, gold-plated hands, solid gold appliques, and a taupe calfskin strap.

The second model (Ref. IW359001) comes with a stainless steel case, a silver-plated dial, gold-plated hands and appliques, and a blue calfskin strap.
Both references are fitted with straps made of traceable Swiss calf leather, boasting a natural and soft finish and a contemporary, luxurious look.
The new Portofino Complete Calendar watches will be available as of April 2023 through IWC boutiques, authorised retail partners, or online at IWC.com.
Additionally, the Portofino Complete Calendar is eligible for registration under the My IWC care program, benefitting from a 6-year extension to the standard 2-year International Limited Warranty.
