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

The IWC Portugieser Perpetual Calendar 41mm stands at the apex of the Portugieser collection's horological ambition, housing a perpetual calendar complication that correctly accounts for months of varying length and leap years automatically until 2499 — requiring no manual date correction in the lifetime of any owner. The 41mm stainless steel case encloses IWC's precisely engineered perpetual calendar mechanism, displaying day, date, month, year, and moon phase across the silver dial with the architectural balance and Arabic numeral clarity that define the Portugieser collection. The railway-track minute scale frames the display with characteristic precision. A Swiss self-winding mechanical movement provides reliable power to both the timekeeping and calendar functions. Sapphire exhibition caseback and scratch-resistant sapphire crystal complete the presentation. Paired with a fine leather strap and deployment clasp, the Portugieser Perpetual Calendar 41mm is the ultimate Swiss dress watch for the serious collector.
