Calibre 9909 MC is the first multiple time zone movement to feature in Cartier’s Fine Watchmaking Collection, housed in a Calibre de Cartier watch.

It features a caliber 9909 MC movement, entirely developed and produced within the Cartier Manufacture.

At SIHH, Cartier presented a new version of the multiple time zone complication, which aims to provide:

- the home time with day/night indication, the traveler’s local time, adjustment for summer or daylight savings time and – something quite unique – the time difference between the two selected time zones.

- excellent readability of all the functions in a limited space

- simple setting and checking of all functions and displays.

Home time is indicated on the lower dial in the center of the watch by a day/night hand featuring sun and moon symbols. Local time in the traveler’s location is shown by the main hands, which enable the second time zone to be read directly.

The self-winding Caliber 9909 MC differs from standard multiple time zone movements in that its cities disc is completely integrated into the movement and is visible in a lateral magnifier on the 9 o’clock side of the case, rather than on the dial.

The time in each of the 24 reference cities is read by pressing the pivoting push-piece. Each press reveals a different city, its local time, and the time difference between the home time and the traveler’s time.

As a final innovation, the Calibre de Cartier multiple time zone watch takes the change to and from summer time into account, an important feature in several countries around the world.

To achieve this, the reference scale on the cities disc simply needs to be altered for the five months during which summer time is in operation.

The Calibre de Cartier multiple time zone model is a robust 45mm in diameter.
