IWC Portugieser Annual Calendar 41mm Men's Automatic Steel Watch

The IWC Portugieser Annual Calendar 41mm combines the collection's timeless classical design with a sophisticated calendar complication that distinguishes between months of 30 and 31 days automatically, requiring manual correction just once a year at the end of February. The 41mm stainless steel case houses a Swiss self-winding mechanical movement with generous power reserve, presenting day, date, and month across a beautifully balanced silver dial that maintains the Portugieser's characteristic legibility despite the added complexity. Large Arabic numerals and the signature railway-track minute scale frame the calendar displays with the proportion and restraint the collection demands. A scratch-resistant sapphire crystal with anti-reflective coating ensures clear readability in all conditions. The sapphire exhibition caseback reveals the decorated movement within. Completed with a fine leather strap and a polished deployment clasp, the Portugieser Annual Calendar 41mm is intelligent Swiss timekeeping at its most refined.
