20.DWWTL.OW : MB&F Horological Machine N°2 HM2 Only Watch 2009


There is a butterfly trapped in the engine of the HM2 Only Watch collaboration with American artist Sage Vaughn, and it has no hope of escaping because the complicated movement is wrapped in barbed wire. This emotionally charged piece, a one-of-a-kind interpretation of MB&F’s Horological Machine N°2 is signed by Sage Vaughn and was auctioned at Only Watch 2009, the charity auction benefiting research into Duchenne Muscular Dystrophy, held in Monaco under the patronage of HSH Prince Albert II.

The disease is a genetic disorder affecting boys. It causes a progressive weakening of the muscles that becomes fatal as the child gets older. The Monegasque Association against Duchenne Muscular Dystrophy (AMM) is a leading force in the drive to find a cure.

The HM2 Only Watch 2009 is a unique piece which was auctioned on the 24th September 2009.
