With its round case with straight lugs, the Rotonde de Cartier is one of Cartier's more traditional designs. This collection consists primarily of watches with added complications.
The Rotonde Earth and Moon reference W1556222 was introduced in late 2013 as a limited edition of 50 pieces. The case is platinum and paired to a dial in lapis lazuli with a white gold Roman grid. It was also available in baguette diamond-set case (the present ref. HPI00639) and this version was limited to 15 pieces.
