The upcoming Only Watch 2007 auction to fund research into Duchenne Muscular Dystrophy has seen a number of established watchmakers offering up some fantastic unique versions of their most sought-after models for collectors to bid on for a good cause. Patek Philippe's unique timepiece this year is a special Nautilus 5712 in titanium, with an automatic winding mechanical movement, a moonphase indicator, and power reserve meter. This watch will be sent on a world tour from August to mid-September this year, just before the auction in Monaco is scheduled to take place.
