IWC – Portugieser Annual Calendar

The latest addition to IWC’s repertoire of fine timepieces, the Portugieser Annual Calendar is the result of five years of research and development. Powered by the IWC-manufactured calibre 52850, the annual calendar shows the month, date and day in three separate windows at 12 o’clock. A small seconds sub dial is at 9 o’clock and opposite it is the power reserve display. Equipped with 7 days of power, the watch requires one adjustment at the end of February to compensate for leap years. The 44.2 mm timepiece is available in stainless steel or 18-carat red gold with a silver-plated dial, or in stainless steel with a midnight blue dial. All versions are fitted with black Santoni alligator leather straps.
