Description:

The IWC Portugieser Annual Calendar ref. IW503502 is a refined complication within IWC’s iconic Portugieser collection, balancing technical sophistication with timeless design. Housed in a 44.2 mm stainless steel case, it features the signature clean Portugieser aesthetic with a silver-plated dial, applied Arabic numerals, and elegant feuille hands. The dial displays an annual calendar across three windows at 12 o’clock—showing month, date, and day—requiring adjustment only once a year at the end of February. Powered by the in-house Caliber 52850, the watch offers an impressive 7-day power reserve, visible through the sapphire case back alongside its beautifully finished rotor. Blending classic maritime-inspired styling with practical complexity, the IW503502 embodies IWC’s mastery of understated yet highly functional haute horlogerie.

Good condition with some signs of wear.
