Watches and Wonders 2024: IWC Prepares the Portugieser Line for Eternity (With Live Photos and Video)
IWC Schaffhausen is relaunching its entire Portugieser collection and adds three new dial colors at Watches & Wonders 2024. Hit the play button for a quick introduction:
The horological headliner is undoubtedly the new Portugieser Eternal Calendar (Ref. IW505701), a watch that can calculate leap years correctly until at least the year 3999 (sinceit has not yet been officially decided whether the year 4000 will be a leap year or not).
A newly engineered 400-years gear ensures that the calendar automatically skips three leap years over four centuries – an event which will occur for the first time in the year 2100. Another key feature of this new watch is the extremely precise moon phase display: Thanks to a newly developed reduction gear, the brand's typical Double Moon phase display will only deviate from the moon’s orbit by one day after 45 million years.
The Portugieser Eternal Calendar features a 44.4-mm platinum case. The extensive use of glass elements such as a glass dial and double box-glass sapphire crystals help to better showcase the mechanism. Movement inside is the newly developed IWC-manufactured 52640 caliber, which features the brand's Pellaton winding system and builds up a power reserve of seven days (168 hours) in the two barrels. Parts of the winding system that are subject to extremely high stresses are manufactured using zirconium oxide ceramic. Like all new Portugieser models, the Portugieser Eternal Calendar is fitted with a finely crafted curved leather strap from Santoni, a renowned Italian manufacturer of luxury shoes and leather accessories.
