IWC Portuguese Perpetual Calendar Watch Series IW503502

The watch features a double-sided anti-reflective domed sapphire crystal glass. The dial is white with white markers. The perpetual calendar display is cleanly designed, showing the month, date, and day in three separate semi-circular apertures located between the 11 and 1 o’clock markers. It has a small seconds subdial at the 9 o’clock position and a power reserve indicator at 3 o’clock. The outer track displays minute graduations along with Arabic numerals for hour markers. The layout is neat and highly legible, making it convenient to read the time and date.
