Lunar Solar Smartwatch

Any smartwatch owner, or anyone who's ever read a smartwatch review, knows battery life is one of their most significant issues. The Lunar Solar Smartwatch overcomes this with a small, transparent panel that collects energy from both the sun and artificial light. As a result, you won't need to charge it every night — or at all. Notifications, fitness info, and more are displayed discretely on the dial via a series of LEDs, and for more detailed information, all your stats get synced to a companion app on your phone.
