IWC Portugieser Perpetual Calendar 42 mm Stainless Steel White Dial

The IWC Portugieser Perpetual Calendar 42 mm captures the full poetic complexity of haute horlogerie within one of the Portugieser collection’s most elegant case designs. Crafted in polished stainless steel, the 42 mm silhouette maintains the collection’s iconic nautical proportions while offering a refined, contemporary presence on the wrist.

The white dial is a masterclass in balance and precision, featuring IWC’s instantly recognizable perpetual calendar layout: a month display at 6 o’clock incorporating a richly rendered moon phase, a weekday indicator at 9 o’clock, and a date display at 3 o’clock. Each subdial integrates seamlessly into the Portugieser’s signature railway-track chapter ring and applied gold-tone Arabic numerals, creating a harmonious visual experience despite the mechanical complexity beneath.

At the heart of the watch lies IWC’s sophisticated perpetual calendar mechanism, engineered to automatically account for the varying lengths of months and leap years—with accuracy extending for centuries when kept running. The look is completed with a luxurious black alligator leather strap, adding depth, texture, and classic sophistication.

This reference embodies the highest tier of IWC craftsmanship: technical, poetic, timeless, and unmistakably Portugieser.
