The first Only Watch auction in 2005 was so wildly successfulâ€”raising €1.9 million Euros for charity (Duchenne Muscular Dystrophy)â€”there was little doubt they'd try to follow it up. Two years later, it's back with more rare machines from today's most desirable brands. The event, commissioned by Prince Albert II of Monaco, will offer 35 limited edition and one-of-a-kind prototype watches, or as the horologically correct say "Piéce Unique." The watches will be auctioned at the upcoming 2007 Monaco Yacht Show by Antiquorum. Last year's largest fundraiser was the €285,000 collaboration by Richard Mille and Philippe Starck. They teamed up again for the ultra-futuristic model titled, â€œAn integral interpretation in titanium" (pictured right). See my other highlights (and info on those pictured below) here.
