The new Rotonde de Cartier calendar watch expresses this desire. Efficient and decent, it reflects the balance between tradition and modernity that only large watchmakers can find.

The annual calendar is a new star in the watchmaking industry. It has been successfully commissioned for less than 15 years. However, the annual calendar has quickly become an indispensable date display function for daily watches. In fact, the annual calendar is easy to operate and does not require precise adjustment, but the Cartier watch had no annual calendar function before. Cartier Watch Factory’s movement development team integrates it into Rotonde de Cartier watches, providing accurate and complete calendar information throughout the year to meet the expectations of fans.
The origin of the calendar function
Simple calendar, that is, the mechanism of indicating the date through the window or hands, must be manually adjusted at the end of the 30 days (bimonthly) to ensure that the watch is synchronized with the ephemeris. However, this simple corrective action is often overlooked, and it may cause small errors every month and need to be corrected manually.
Manual operation of the winding crown, skipping the 31st, and directly displaying the 1st, this is a heavy task imposed on the machine, and it is also extremely boring. Because of this, during the Enlightenment, after the birth of the perpetual calendar watch, as long as the watch remained in operation, the dial directly displayed the calendar information, and no further adjustment was needed. Although this watch with superb digital memory ability is fascinating, if the watch is stopped for a long time, the watch owner may still be in trouble. For such highly precise works, if you want to readjust the calendar display, there are always many operating steps. Sometimes, the watch owner can only ask professionals to help.
Rotonde de Cartier Year 9908 MC automatic winding movement
In order to avoid the restrictions when starting the watch, the Cartier movement design team developed a reliable, efficient and tough mechanism for the Rotonde de Cartier calendar watch, which can automatically adjust the date at the end of each month (30-day and 31-day month management) , And display the day, month, and year at the same time, except that February 28 or February 29 to March 1 requires manual intervention, and no adjustment is required. Cartier’s new 9908 MC calibre has a special mechanism. With the winding crown, all the calendar information (day, date and month) can be adjusted. This adjustment is simple and there is no adjuster on the case, creating an ideal and comfortable daily application mode.
Innovative and practical movement
Cartier chose the 1904MC movement for the Rotonde de Cartier calendar watch, and integrated the calendar device directly into the main splint. After repeated research, the watch has a large date window that can independently display two digits at 12 o’clock. Turning the winding crown can quickly adjust the different indicators of the calendar. These designs are all favored by exquisite watch lovers. This in-house developed movement is unique and concise, with many important features, including an independent two-digit large date display half-instant jump mechanism (one-hour jump), which ensures the ideal timing stability of high-end watches. In this structure, the needle wheel on the large single-digit display panel drives the ten-digit four-pointed star wheel to rotate. The single digit display is the true core component of the calendar system, and has another secret—a simple and clever device combined with a month memory cam installed on the single digit date thin outer wheel, which can be accurate once the month is adjusted Display 30 or 31 days without error. The device has unparalleled high efficiency and is specially designed for calculating the lengths of odd and even months (except for February, which changes from 28 days to 29 days every four years), even if it is subject to large vibrations, it will never affect accuracy. Cartier designers associate the date display with the day of the week and month hand indicators to rationalize this automatic almanac function and undergo rigorous testing to enable it to cope with daily vibrations.

The ultra-thin bezel has a soft curve to make the structured dial more exquisite. The top of the dial is decorated with a ‘sun pattern’ silver-plated grille, matched with black transfer Roman numerals, and the flame blue steel sword-shaped hands rotate around it. This arrangement allows different levels of time to be displayed in front of the eyes, and simultaneously divides two radial concentric silver areas, with the week of the week in the center and the name of the month on the four weeks. At the bottom of the fine grooves, on the two ‘hammer-shaped’ hands, only the ends are visible in red. When correctly set, the calendar information can be indicated, making the large double-window large date display at 12 o’clock more abundant. In this configuration, the size of the winding crown is carefully designed for easy gripping. It can be used to wind the 9908MC annual calendar movement. At the same time, the calendar can also be adjusted by adjusting the different groove positions of the crown. This low-key, subtle, yet fascinating complication watch has a transparent case back, giving people a glimpse into the subtleties of fine watchmaking craftsmanship.
