The layout of the dial utilizes three distinct sub-dials to display the various features of the perpetual calendar. At the 3 o’clock position is an aperture for the date, at 6 o’clock is an aperture for the month and moon phase, and the third aperture at 9 o’clock depicts the day of the week. A roman numeral index at 12 is the only numeric hour marker, while the rest use thin geometric indices. For the gold iteration, IWC uses corresponding gold detailing in the indices, hands, and moon phase, while the steel version uses its respective cool-toned detailing instead.
