Solar-powered watches are nothing new, but being more power-hungry beasts, solar-powered smartwatches are a different story. A San Francisco-based startup called LunaR now claims to have bridged the divide by developing a smartwatch that never needs to be plugged in for a recharge as it draws all the energy it needs from the sun.
The LunaR... includes sleep and activity tracking, along with integration with social media and messaging apps to bring notifications to the wrist through an embedded LED array.
At the heart of what the creators claim is the world's first solar-powered smartwatch is (unsurprisingly) a breakthrough in solar technology. With a clear solar panel layered over the watch face, it's claimed the LunaR can harvest energy from both natural and artificial light. So much so, that with as little as one hour of daily exposure to light, its 110-mAh lithium-polymer battery can apparently stay fully charged.

Solar powered watches in general have been around for a long time. My friend has one and the only time charging is an issue is long international flights, like USA to Australia. But you can leave it under a desk lamp for an hour to charge in the absence of the sun.
