MB&F comes out with a unique interpretation of its outstanding Horological Machine No. 2 for the Only Watch auction. Held every two years, the proceeds from the auction go towards supporting the fight against Duchenne Muscular Dystrophy (DMD), a rare genetic disorder that affects one in 3,500 young boys. The Horological Machine No. 2 is an apt vehicle to support this cause because creator Max Busser was inspired in the first place by the meccano model kits that were his toys as a child.

In this one-of-a-kind watch, we see the vision of both Busser and artist Sage Vaughnn. Vaughnn presents DMD as the blackened gold barbed wire trapping both the movement and the blued gold butterfly. The butterfly has a clipped wing to show that the struggle is all too often in vain. Aside from this, astute watch lovers will notice two sapphire domes on a transparent top plate that is, interestingly, also sapphire crystal. Busser informs us that these domes have been soldered onto the top plate, which is a first in the watch industry. Of course, the superlative case remains one of the most complicated in the business.
