Apparently, manufacturing of one of the most durable wristwatches in the world was just not enough for electronics maker Casio. To celebrate the 40th anniversary of Earth Day, the company decided to flex their clock-making prowess by taking their popular G-Shock series to the next level – making them run on solar power.
Casio has developed three new models in time for Earth Day. Evocative of the original G-Shock wristwatch (which was originally released in 1983), the new timekeepers will now feature a solar panel in the front that will power the battery. To top it off, all packaging for these three models will be made out of 100% recycled paper. The solar powered G-Shocks will come in three colors and will be available soon.
