MB&F Goes Heavy on the sapphire with their HM6 SV
Horological Machine No.6 (HM6) ‘Space Pirate’ has been designed to operate in the hostile environment of space: the space on your wrist.
In each of the four corners of HM6's biomorphic case is a 360° sphere, capped top and bottom by transparent sapphire crystal domes, or in the case of HM6-SV, transparent sapphire crystal plates displaying the movement within. Up forward, two semi-spherical indications rotate vertically, displaying hours and minutes. Back aft, driven through multiplying gearing by the automatic winding rotor, twin spherical turbines spin horizontally, automatically regulating the winding system in case of excessive speed to reduce stress and wear.
