Limited Edition  In each of the four corners of HM6’s biomorphic case is a 360° sphere, capped top and bottom by transparent sapphire crystal domes. Up forward, two spheres rotate vertically respectively displaying hours and minutes. Back aft, the twin spherical turbines spin, regulating the automatic winding system to reduce stress and wear. The transparent cupola on top houses a flying tourbillon and offers a tantalizing glimpse into the sophisticated engine inside. The sapphire crystal display portal on the back reveals more of the 475 finely finished components making up the highly complex movement, which required over three years of development. The sapphire crystal plates of the HM6-SV and Alien Nation editions offer even more comprehensive views − top and bottom − to the movement within. The number of pieces made in the Horological Machine N°6 series comes to a total of exactly 100.
