IWC Portuguese Perpetual Calendar Watch Series

The IWC Portuguese Perpetual Calendar watch series features a double-sided anti-reflective arched-edge glass mirror and a white dial with white studs. The calendar display is simple and sleek, with three separate semicircular windows displaying the month, date, and day of the week, positioned between 11 and 1 o'clock. A small seconds dial displays the power reserve at 3 o'clock and a small seconds dial at 9 o'clock. The watch features a track-style minute track and Arabic numerals for the hours. The neat layout makes reading the time and date easy.
