The 2024 IWC Portugieser Eternal Calendar is IWC's first century calendar. It is an innovation based on the brand's existing perpetual calendar module, with all displays adjusted at the touch of a button via the crown. Unlike perpetual calendars programmed in four-year cycles, the IWC Portugieser Eternal Calendar has an additional mechanism that ensures that the Eternal Calendar automatically skips three non-leap century years in 400 years, without the need for adjustment in non-leap century years.
The Portugieser Eternal Calendar is equipped with an unprecedented moon phase display. Thanks to a newly developed reduction gear system, it theoretically deviates from the lunar orbit by only one day after 45,361,055 years, winning the Guinness World RecordTM. The Double Moon™, which features a titanium chassis with two blue dots and a glass disc rotating above it, theoretically only needs to be adjusted once after 45 million years.

The IWC Portugieser Eternal Calendar watch features a platinum case, and the dial, mirror and case back are all box-shaped sapphire glass lenses, which fully display the transparent dial and the IWC-manufactured 52640 movement inside. The Pellaton automatic winding system uses a bidirectional rotating rotor to provide two barrels with a power reserve of up to 7 days (168 hours).
