The RM 56 made a phenomenal buzz when it has  been presented for the first time at SIHH 2012. Its case entirely made out of sapphire explains the intensity of the wouahou effect. Thanks to this material, this evolution of the previous RM 008 reveals entirely the details of its movement. And in addition to the technical challenge of creating such a case, which implied about 1000 hours of machining!, over 400 parts of the tourbillon split seconds chronograph caliber have been redesigned and most of them realized in titanium to reduce the weight.
