You’ve seen the Annual Calendar, now here’s the new Perpetual Calendar from Cartier.  More precisely, the Cartier Rotonde de Cartier Perpetual Calendar in pink (Ref. W1556217) and white gold (Ref. W1556218).  This piece is a fairly traditional interpretation built around Cartier’s 9422 MC perpetual calendar movement.  I particularly like that the days of the week are indicated by a retrograde hand.
