Designed like an amphitheater, with the intention of clarifying the perpetual calendar's indications, the Rotonde de Cartier Astrocalendaire’s display is an incredible watchmaking feat.
Arranged three-dimensionally in concentric levels, the display of the perpetual calendar’s functions is spread over the different levels: the day is indicated on the first. It is followed by the month on the second, which is itself surmounted by the date. Thin windows move along these tiers. The perpetual calendar’s final function is indicated by a hand located on the back of watch and shows what type of year it is: a leap year or a normal year.
