About this item

Brand: IWC
Collection: Portuguese
Model: Portuguese
Reference: IW5057-01

Winning the highest honor at the 2024 Grand Prix d'Horlogerie de Genève solidifies the Portugieser Eternal Calendar as a historic achievement in modern horology. IWC programmed its secular calendar to account for the Gregorian calendar's leap-year exceptions, automatically skipping three leap years over every 400-year cycle. Glass sub-dials float beneath double box-glass sapphire crystals, giving the display a light and layered appearance without obscuring the mechanical complexity beneath. Inside the heavy platinum housing, the automatic Caliber 52640 utilizes twin barrels to deliver a 7-day power reserve, expertly capturing the beauty of fleeting moments within a mechanical frame built for eternity. Offered unworn, this IWC Portugieser Eternal Calendar Platinum Watch IW5057-01 comes complete with its official paperwork and manufacturer's box.
