Introduced in 2015, this reference belongs to the Portugieser Perpetual Calendar line and continues within IWC’s long standing production of high complication dress watches.
A perpetual calendar mechanism governs all major calendar indications, including date, day, month, and moon phase, while automatically accounting for leap year cycles without manual correction. The dial is arranged in a structured multi register layout that separates each function for clear readability despite the complexity.
Large proportions, typically around 44mm, define the wrist presence of this model and support the spatial requirements of the complication system. Arabic numerals and leaf shaped hands maintain the traditional Portugieser design language, ensuring clarity and visual balance across the dial.
An automatic in house movement drives the entire system, delivering consistent mechanical performance while powering both timekeeping and calendar functions through continuous motion.
Precision calendar engineering defines the identity of this Portugieser reference, where mechanical complexity is integrated into a clean and balanced dial architecture.
Each calendar indication is positioned with structural intent, allowing multiple time related functions to be read without visual confusion. The moon phase adds an additional astronomical layer, reinforcing the watch’s connection to traditional horological craftsmanship.
Within the Portugieser family, this model represents IWC’s approach to combining advanced mechanical capability with restrained classical design principles.
Availability is typically concentrated within the pre owned market due to the model’s high value positioning and extended production cycle.
This reference appeals to collectors who value full calendar automation combined with traditional dress watch aesthetics. Once correctly set, the perpetual calendar system operates for long periods without adjustment, making it suitable for those who appreciate mechanical independence.
Pre owned sourcing also allows evaluation of movement performance, calendar accuracy, case condition, and dial clarity based on real world use.

Choosing BQ Watches ensures expert handling of high complication timepieces where precision, authentication, and valuation accuracy directly affect long term ownership value.
Perpetual calendar watches require specialist level verification because every calendar function must operate in perfect synchronization, including date progression, month cycles, leap year correction, and moon phase alignment. BQ Watches conducts full functional testing on these complications rather than relying on surface inspection, reducing the risk of unnoticed mechanical discrepancies.
Accurate valuation is essential for a model positioned within the high end IWC complication range. Pricing is determined using real market performance of comparable Portugieser Perpetual Calendar references, ensuring both buyers and sellers are aligned with current secondary market conditions rather than broad or outdated estimates.
At BQ Watches, buy, sell, exchange and valuation services are handled through a process built around technical verification and market accuracy, ensuring that every transaction reflects the true mechanical condition and real world value of the watch.
This structured approach maintains confidence at every stage of ownership transfer, particularly for perpetual calendar watches where complexity directly influences both performance and value.
