Overview

The IWC Portugieser Perpetual Calendar 42 (ref. IW344203) brings one of watchmaking's most complex complications to a 42.4 mm stainless steel case, pairing it with a clean silver dial that keeps the display legible at a glance. Introduced in 2020, it represents IWC's commitment to making the perpetual calendar accessible within the long-running Portugieser family. Calibre 82650 powers the watch, offering a perpetual calendar mechanism that accounts for months of varying length and leap years without manual correction until 2100.

History

The Portugieser line traces its roots to the late 1930s, when IWC produced large-cased, legible watches originally commissioned by Portuguese merchants. Perpetual calendar variants have been a cornerstone of the collection for decades, evolving through successive generations of in-house movements. The IW344203, introduced in 2020, marked a refinement of the 42 mm perpetual calendar format, bringing the complication into a more contemporary case size while retaining the collection's characteristic dial architecture. Its stainless steel execution broadened the model's appeal among collectors who favour the metal's versatility and wearability.

Notable points

  • 42.4 mm stainless steel case strikes a balance between the Portugieser's historically large proportions and modern wearability.
  • Calibre 82650 is an in-house perpetual calendar movement requiring no date correction until the year 2100.
  • The silver dial follows the Portugieser tradition of clean, uncluttered layouts with subsidiary registers for day, date, month, and moon phase.
  • Perpetual calendar display uses a four-digit year aperture, a hallmark of IWC's approach to the complication.
  • Introduced in 2020, the reference continues IWC's long-standing practice of offering high complications in the accessible Portugieser steel configuration.
