There are plenty of smartwatches available on the market. Not too many of them are solar powered though. LunaR is an elegant watch powered by sunlight. It offers activity tracking, phone notifications, sleep monitoring, and dual time-zones support.
LunaR’s solar panel harvests enough energy to keep the watch running all the time. Its LEDs and vibration tech work with your favorite apps to help you keep up with your notifications. Expected to ship in March.
