The Rotonde de Cartier Annual Calendar watch offers a contemporary display and prioritises readability and operation because the movement requires setting just once a year (when the date changes from the 28th or 29th February to 1st March.)

For this watch, Cartier chose to incorporate a mechanism directly into the plate of the calibre 1904 MC. The Manufacture calibre 9908 MC displays the date at 12 o’clock with two independent numerals. To simplify its operation even more, the mechanism allows all the information (day, date and month) to be managed via rapid turning of the winding crown to adjust the calendar’s different indications. This simple setting system, devoid of any kind of correcting device on the case, offers maximum ease of use. Three adjustments are therefore possible: the winding of the movement, time setting and date setting.

The dial can be read in three ways: the large date, the circle of days around which a red indicator turns, the month aperture and the hours, which are shown by the progress of the blued-steel hands above black transfer Roman numerals.

The dial boasts a “sunray” guilloché design in its centre that radiates elegance. This Maison signature highlights and accentuates the volume and 40 mm diameter of the watch.

The Rotonde de Cartier Annual Calendar watch exists in two 40mm versions: in 18-carat pink gold on a brown leather strap or in white gold, with a grey dial and black alligator-skin strap.
