In honor of Monaco, the city that will host the Only Watch 2011 charity watch auction, participating brand Romain Jerome has come up with this special piece unique watch. The dial is a piece of rock based on the stone that Monaco was literally built on - they call it the "Rock the Rock DNA" watch.

Based on the DNA style case, the watch has a black ceramic bezel and PVD black case. The dial has longitude and latitude indicators that likely mark the sport of the city (or where the stone was taken). The strap looks to be black alcantara leather. Overall this is actually a really cool looking timepieces. I love the black and tan color with red accents. Only one of these Rock the Rock DNA watches will be made and it will be auctioned off in September at Only Watch 2011.
