#1 Chopard 201 karat
This gaudy timepiece may look like a piece of costume jewelry, but it is far, far from it. The Chopard 210 karat is layered in 201 karats of colored diamonds and resembles a bracelet more than it does a wristwatch. It is not going to be a good fit for someone looking for a practical timepiece, but, of course, this monstrosity of decadence is by no means practical. The piece is so expensive that there is no list price for it and has an estimated value of close to $30 million.
