Rotonde de Cartier Jour et Nuit

Rotonde de Cartier Day and Night watch with retrograde moon phases
A play of shadow and light
 
 
Elegant and contrasted, the Rotonde de Cartier Day and Night watch with moon phases charts time thanks to the strict aesthetics of a split dial: the upper part is devoted to the indication of the day, night and time, while the lower part focuses on the moon-phase display.
 
A creative dial that follows in the Maison's great stylistic tradition  
 
Moon phases represent a historic complication for the Maison and have inspired some of Cartier's most beautiful creations, starting with the “comète” clock created in 1913. In turn, the Rotonde de Cartier Day and Night watch with retrograde moon phases continues the tradition of this subject of artistic expression with the stylised representation of a dial with two dimensions.   
 
The sun and the moon indicate the time by turns. They appear alternately, the sun represented figuratively and the moon in a more abstract form, its phases displayed with rhythmic elegance.  
 
A complete vision of time
 
The Rotonde de Cartier Day and Night watch is driven by the self-winding calibre 9912 MC which offers a complete and tangible measure of time. This instructive reading enables the wearer to simultaneously identify the hours of the day, the hours of the night and the lunar cycles.
 
This innovative approach was prompted by Cartier's desire to celebrate the timeless day and night complication with a generous display diameter that is among the largest ever conceived.
 
A world in itself, characterised by an elegance and symbolism that Cartier perfects with a moon phase indicated by a hand with a crescent-shaped pointer that is itself retrograde.
