Portugieser Perpetual Calendar : IW502218

The IWC Portugieser Perpetual Calendar IW502218, released in 2006, is a distinguished model within the Portugieser collection. It features a 42.3 mm case crafted from white gold, complemented by a transparent caseback that offers a glimpse into its mechanical intricacies. The watch showcases an ardoise-colored dial, which hosts the notable 'Single Moon' moonphase display, allowing for precise lunar readings specific to its hemisphere. Inside, it houses IWC's self-winding movement paired with Kurt Klaus' perpetual calendar module, a design that traces its origins to the 1985 Da Vinci but modified here to accommodate the larger dimensions of the 7-day movement. From 2006 to 2007, this model was powered by the calibre 51610, before transitioning to the calibre 51613 from 2007 onwards. This watch not only embodies technical sophistication but also reflects a classic and timeless style characteristic of the Portugieser lineage. Its elegant combination of refined materials and advanced horological features makes it a notable piece for those interested in both traditional watchmaking and contemporary design innovations.
