MB&F @ HM3 MEGAWIND Wind Final Edition

MB&F HM3 has an inverted movement so that its operation can be easily seen from the dial side and MEGAWIND Final Edition follows the same principle. Harmoniously crafted bridges, rapidly oscillating balance wheel, gearing and MB&F’s iconic battle-axe automatic winding rotor are all open to view on the dial side. This allows the wearer to fully appreciate the art and craft of the HM3 engine by drawing the viewer’s gaze inside the highly complex machine; a machine comprising more than 300 fine-finished, high-precision components. The movement of HM3 has been literally turned upside down to allow for an uninterrupted panorama of the powerfully graceful rotation of the 22k gold and titanium winding rotor and the high-speed oscillations of the balance wheel. Jean-Marc Wiederrecht, winner of the inaugural award for Best Watchmaker at the 2007 Grand Prix d’Horlogerie de Genève, was entrusted with turning the drawings and designs of Maximilian Büsser and designer Eric Giroud into horological reality and, with his team at Agenhor, he surpassed the challenge.

Until MEGAWIND Final Edition, adding Super-LumiNova to the display was thought to be impossible as the lume has to be hand painted on the curved cones of HM3. While no longer impossible, the technique for applying the lume is anything but straightforward. White paint is first hand-painted onto the numeral shapes of an indication cone projected flat. A silicon stamp is pressed onto this flat surface to pick up the white paint in the correct shape and then the operator carefully uses the stamp to evenly transfer the paint to the three dimensional cone. The white paint not only serves as a template but also acts as a reflector for the Super-LumiNova, which is then painstakingly applied by hand as a second layer. While Super-LumiNova comes in many colours, the active pigments are always green and other colours partially mask the green glow so they are less bright. For HM3 MEGAWIND Final Edition, MB&F uses C3 grade Super-LumiNova, which emits the purest and brightest light.
