The Light-Powered line of Orient watches contains many classic, versatile watch designs with a surprising power source--light. The solar cell beneath the dial absorbs light to power the watch from many sources, not just the sun, and retains a charge of 4,000 hours (over 6 months) from just a six-hour charge! The watch designs themselves are sporty and trendy, and the rechargeable battery contains no harmful chemicals. With a watch from this collection, you can be confident that you aren't harming the environment and that you look great at the same time. With this collection, Orient is establishing a new standard in solar-powered watches.
