One of the highlights among Cartier’s novelties which will be officially presented at the upcoming Salon International de la Haute Horlogerie is this masterpiece that combines tourbillon and moon phase complications. Plus, the moon-phase indicator is designed in a truly unique way, putting these two complications in an interesting interplay. Produced in just 50 pieces, new Cartier Rotonde de Cartier Earth Moon watch presents the brand’s famous classic elegance and the high-end technology, which is completely revealed on the back-side of the robust case.
Several things immediately pull the attention: First, there is a beautiful interface made of lapis luzili, a semi-precious stone with an authentic, intense blue color. Furthermore, you can see a finely crafted off-centered dial, presenting the globe, surrounded on both sides with oversized Roman numerals. This piece of art is made of platinum, just like a robust, 47 mm case. You can enjoy nicely polished surfaces of perfectly rounded case, its lugs, push-pieces and a crown. Of course, a blue sapphire cabochon on the top of the crown is something that we expect to see on every Cartier’s model.
All these elements are so impressive that one could almost lose sight of the actual highlight of Rotonde de Cartier Earth Moon watch. It is located at the 6 o’clock position and you can easily notice that we are talking about the tourbillon cage. However, just a few days every month the wearer has the opportunity to see it completely. Is it just a coincidence that these days correspond to the full moon? Actually, no it is not. Cartier had the brilliant idea to use the tourbillon cage as a moon-phase indicator. When it is a full-moon period, it is revealed completely, while on the rest of days, it is partially or completely covered by a moving stone lapis lazuli disc, representing the shadow that coveres the moon. Great thing is that this disk is activated only on demand of the wearer (by pressing the button). Thus, those of you who prefer to enjoy the perfectly synchronized motion of the cage do not need to wait the moon in order to see this.
Another great feature is the second time-zone disc that rotates around the globe at the 12 o’clock position. It is combined with the regular time display that includes the brand’s signature blued steel hands. The GMT time indicator can be adjusted via the second pusher, placed at the four o’clock position.
The mechanical support for this original concept came from Renaud & Papi which often collaborate with Cartier when it comes to highly complicated watches. A Calibre 9440 MC hand-winding movement is completely revealed through the transparent case-back, offering its beautiful finishes. It includes 362 parts and 40 jewels and ensures three days of power-reserve. Paired with a black alligator strap, Rotonde de Cartier Earth Moon timepiece will be available at the price of 200,000 EUR (around $275,000).
