Prada just introduced a new solar powered watch. It’s not on the usual sleek european style look, it’s on a lot more sporty and rugged tip. Unfortunately, people outside of Europe wonâ€™t have much access to cop this joint. This watch can stay charged up for a month by a small drizzle of sunlight. It also has a radio receiver, but it only picks up stations in Europe. The Prada Solar Watch is available at Prada retailers in Europe and on Pradaâ€™s European online shop. 1500â‚¬.
