IWC Portofino Perpetuel Calendar automatic silver dial red gold box leather strap 40 mm

A grand complication joins the Portofino collection

The Portofino Perpetual Calendar IW344602 introduces one of IWC Schaffhausen's most iconic complications into its timeless Portofino family. Developed by master watchmaker Kurt Klaus in the 1980s, the Manufacture's perpetual calendar is renowned for its ingenious construction, allowing every indication to be adjusted exclusively via the crown. Housed in a refined 40 mm case, it delivers one of the most elegant interpretations of this prestigious complication.

A refined silver-plated dial

The elegant silver-plated dial combines blued feuille hands, applied baton markers and Roman numerals to create a beautifully balanced display. Three subdials indicate the day, date, month and leap year, while the moon phase display at 6 o'clock adds a poetic touch. Thanks to an exceptionally precise reduction gear train, the moon phase will deviate by only one day after 577.5 years.

The legendary IWC perpetual calendar

The perpetual calendar automatically recognises the different lengths of the months as well as leap years without requiring manual correction until 2100. All displays remain perfectly synchronised and can be adjusted entirely via the crown, making Kurt Klaus's ingenious mechanism one of the most practical and user-friendly perpetual calendars in Swiss watchmaking.

The IWC manufacture calibre 82650

Powering the watch is the IWC-manufactured calibre 82650. Equipped with the renowned Pellaton winding system featuring highly wear-resistant ceramic components, it delivers a 60-hour power reserve. Through the sapphire crystal case back, the movement reveals its refined architecture, skeletonised rotor with a solid gold medallion and meticulous finishing that showcase IWC Schaffhausen's renowned craftsmanship.

The prestige of 750/1000 red gold

The polished 40 mm case is crafted from 750/1000 red gold, whose warm tones beautifully complement the silver-plated dial. A domed sapphire crystal with anti-reflective coating enhances the watch's elegant profile, while the blue calfskin leather strap equipped with the EasX-CHANGE® system provides exceptional comfort and effortless strap changes without tools.

A grand complication for everyday elegance

The Portofino Perpetual Calendar IW344602 demonstrates that a grand complication can also be an everyday companion. Combining a timeless design, a user-friendly perpetual calendar and an exceptional manufacture movement, it is an outstanding expression of contemporary Swiss haute horlogerie.
