IWC Portugieser Perpetual Calendar

The IWC Portugieser Perpetual Calendar stands as a true masterpiece of haute horlogerie.
Powered by the IWC-manufactured calibre 52610, it features twin barrels, the Pellaton winding system, and a remarkable 7-day power reserve.
Its perpetual calendar mechanism automatically accounts for leap years, displaying the date, day, month, four-digit year, and moon phases with unmatched precision—requiring no manual correction until the year 2100.
With its clean dial symmetry, Arabic numerals, and feuille hands, the watch exudes classic refinement and mechanical brilliance.
A sapphire crystal case back reveals the intricate craftsmanship that defines IWC’s engineering excellence.
