MB&F is closing the book on one of its wildest designs, the Horological Machine N°6. The HM6 Final Edition's mothership-like case will be released in stainless steel and is detailed with polished lines that contrast with its satin-finished surfaces. Various elements of the watch have also been finished in a blue PVD, which can be found on the platinum oscillating weight as well as the hour and minute spheres. The centerpiece of the design is the flying tourbillon, which features a retractable shield and sits at the core of the 475-component movement. 

Limited to eight pieces.
