Portofino Perpetual Calendar Rose Gold Silver Dial 40mm

About the Model

The IWC Portofino Perpetual Calendar (ref. IW344602) introduced in 2022 brings the elegance of the Portofino line into grand complication territory, combining formal simplicity with technical gravitas. Presented in polished 18ct rose gold, its 40mm case frames a silver dial punctuated by harmoniously arranged calendar subdials and a moonphase display at 12 o’clock.

Powering the watch is IWC’s in‑house calibre 82650, a self-winding movement featuring a perpetual calendar mechanism that automatically accounts for leap years and varying month lengths. The moonphase complication is designed to deviate by just one day in 577.5 years, underscoring the movement’s remarkable mechanical precision. A 60-hour power reserve and Pellaton winding system enhance both autonomy and resilience. The case offers water-resistance to 50 m and is fitted with a sapphire crystal caseback revealing the Côtes de Genève finishing.

At just 40mm, the Portofino Perpetual Calendar ref. IW344602 delivers a complication-rich profile in a proportion that remains classically wearable – a rare trait among perpetual calendars. Its restrained aesthetics and mechanical finesse offer lasting appeal to collectors inclined toward timeless design and technical substance.Read More
