IWC Portugieser Perpetual Calendar IW502109

Portugieser Perpetual Calendar : IW502109

The IWC Portugieser Perpetual Calendar IW502109, released in 2003, is a distinguished addition to the Portugieser collection. This timepiece features a substantial 44.2mm platinum case with a transparent caseback, allowing for a view of the intricate inner workings. At the heart of this model lies the self-winding 7-day movement, which was originally paired with Kurt Klaus' innovative perpetual calendar module. One of its distinguishing features is the 'Double Moon' moonphase display, which provides readings for both the northern and southern hemispheres—an element that adds both functionality and visual interest to the watch's design. The silver dial complements the platinum case, creating a classic yet striking appearance. Over its production period, this reference transitioned through different calibres, including the 50611, 51612, and 51614. The IW502109 exemplifies IWC's dedication to combining technical prowess with timeless aesthetics in their horological creations.
