This brand new release reinvents the famous Rotonde de Cartier Day & Night model. Powered by a mechanical self-winding caliber 9912 MC, the timepiece is cased in palladium and measures 43.5mm. A blue sapphire cabochon, white galvanized guilloché dial, alligator strap and a double adjustable folding buckle in 18K white gold completes the luxurious look. A closer inspection on the face reveals a 'sun and moon' disk that rotates over the course of 12 hours to indicate day and night, while the retrograde hand also helps denote the phases of the moon in the form of a lunar crescent. Now available via the jeweler’s own website.
