This year at the SIHH 2015, Cartier the French Maison that is very well known for their very high end jewelry creations, presented a handful of novelties that will continue to position the brand as one of the top haute horlogerie houses. While most of these novelties are not necessarily the most affordable from a pricing standpoint, there are for sure exceptional when it comes to watchmaking. In 2010, Cartier offered a new vision of traditional tourbillon design with the Rotonde de Cartier Astrotourbillon watch. For the first time, this complication was no longer limited solely to its function, which consists of guaranteeing better timekeeping and reducing the effects of gravity, but instead was fully incorporated into the aesthetics of the watch. Indeed, unlike classic tourbillons which rotate around their own axis, the Astrotourbillon is distinguished by its elongated cage that enables the balance to make a complete circle of the dial in a minute, thus marking the seconds and evoking a star. In 2012, on the back of research led by the innovation programme responsible for the ID One and ID Two concept watches, which explore, among other areas, the performance of materials never before seen in watchmaking, Cartier decided to use carbon crystal for the Astrotourbillon, thus making it the first Cartier movement available for purchase to benefit from this incredible technical advancement.
