Introduced at Baselworld 2010, the Blancpain Carrousel Sapphire is quite an impressive timepiece. It features a rose gold case with a sapphire crystal on the front, back and on both sides of the case. It even features a sapphire crystal in place of the plates and dial, which creates the illusion that the movement is floating inside the case. It looks really cool in person. Another key feature, is the carrousel movement (a "carrousel" improves accuracy by negating gravity's effects, much like a tourbillon). A carrousel movement is very difficult to produce, and very rare. Accordingly, the price is what you would pay for a tourbillon, or more.
