Montres DeWitt is honoured to have been invited to participate in the Only Watch 2011 Charity Auction in favour of research programmes on the Duchenne muscular dystrophy (DMD), to be held in Monaco on September 22 under the high patronage and in presence of S.A.S. Le Prince Albert II of Monaco. After a first participation in 2005 and, in 2007, the presentation of the WX-1 (concept watch no 1), an exceptionally complicated horological piece of art, DeWitt is presenting this year yet another masterpiece: the X-Watch.
