IWC Portugieser Perpetual IW503702 Watch

IWC Schaffhausen's perpetual calendar was originally developed during the 1980s by former head-watchmaker Kurt Klaus. In 2003, the legendary complication was presented in the Portugieser collection for the first time. Since then, the Portugieser Perpetual Calendar has been a major pillar of the collection. This version features a polished 18-carat Armor Gold® case with a diameter of 44.4 millimetres, an Obsidian dial, gold-plated hands and gold appliques.. A particular highlight is the intricately crafted dial, which is manufactured in a complex process comprising 60 individual steps. All its displays are perfectly synchronized with each other and can be advanced easily via a single crown. The IWC-typical Double Moon™ display shows the moon as it can be seen from the Northern and Southern hemispheres. The Portugieser Perpetual Calendar is powered by the IWC-manufactured 52616 calibre movement, which is assembled from 386 individual parts. The automatic Pellaton winding system features components made of virtually wear-free zirconium oxide ceramic, while the oscillating mass is made of solid gold. The watch is fitted with a black alligator leather strap from Santoni with an 18-carat Armor Gold® folding clasp.
