IWC Portugieser Annual Calendar 44.2mm Steel Silver IW503501

The IWC Portugieser Annual Calendar IW503501 presents IWC’s practical calendar complication in accessible stainless steel with a classic silver-plated dial. The 44.2mm case measures 15.3mm thick, with a sapphire case back and arched-edge sapphire crystal with antireflective coating on both sides.

Powered by the Caliber 52850 Pellaton automatic winding movement with an approximately 7-day power reserve, the annual calendar automatically adjusts for months with 30 and 31 days, requiring only a single manual correction per year at the end of February. The display includes date, day, month, a power reserve display, and small hacking seconds at 9 o’clock.

Presented on a black alligator leather strap, this stainless steel Portugieser Annual Calendar with silver dial offers an accessible entry into IWC’s calendar complications. Water resistant to 3 bar.
