From the brand: IWC Watch Portugieser Perpetual Calendar 44 Silver Moon IW503701. Over the last two decades, the Portugieser Perpetual Calendar has established itself as a key pillar of the collection. Originally developed by IWC Schaffhausen’s former Head Watchmaker Kurt Klaus in the 1980s, the perpetual calendar complication has been continuously improved and perfected over the years. The first Portugieser with a perpetual calendar was launched in 2003. The moon phase display was enhanced with a larger reduction gear by taking advantage of the more generous case dimensions, increasing its accuracy from 122 to 577.5 years. Another innovation was the patented Double Moon display, which shows the moon phase as seen from the Northern and Southern hemispheres.
