Portugieser Perpetual Calendar : IW503301

The IWC Portugieser Perpetual Calendar IW503301, released in 2015, is a distinguished timepiece from the famed Portugieser collection. Crafted in white gold, it features a substantial 44.2 mm case with a transparent caseback, allowing a view of the intricate movement inside. The watch showcases an ardoise dial, which beautifully contrasts with the case material and complements the overall elegant design. Notable for its mechanical prowess, this model is powered by an automatic movement with a 7-day power reserve and employs the sophisticated Pellaton winding system with twin barrels. A defining feature of this watch is its perpetual calendar complication, including a four-digit year display—a nod to the innovative module designed by Kurt Klaus in 1985. Unlike its 5034 counterparts, the IW503301 model opts for a traditional moonphase window. The watch's design subtly pays homage to its predecessors while embracing modern updates such as an arched glass and refined dial elements.
