Green enthusiast Leonardo DiCaprio has just discovered another way to help save the environment. The actor is working with watchmaker Jaeger-LeCoultre to design two luxury watches that will benefit Leo's fund at the California Community Foundation. "We all have to do our part to raise awareness about global warming and the problems we as a people face in promoting a sustainable environmental future for our planet," said Leo. The watches, which are part of the Time to Care campaign, will be available this fall. The first watch is a carbon-fiber-and-titanium Master Compressor Extreme LAB watch that includes Leo's signature and is worth $300,000. The second watch is Jaeger's 175th-anniversary platinum Gyrotourbillon 2 that is worth $400,000. Who knew it took so much green to be green?
