In the 42 mm case of the 9423 MC movement, Cartier has brought together two of the most famous complications in watchmaking: a perpetual calendar and a chronograph. It has the features of a perpetual calendar in the Cartier Fine Watchmaking collection: the days of the week indicated by a retrograde hand, the date written in large Arabic numerals around the dial with the month and leap year counter located at 12 o'clock. In addition, there is an automatic winding high-precision, high-torque mechanical chronograph.
