New G-Shock Rangeman

GPS with MUTHAFUKIN SOLAR ASSISTED CHARGING

The solar charging doesn't keep up with the power drain of the GPS, but it'll let you use the that bit for an hour after 4 hours of charging in 50,000 lux (50% direct sunlight)

The solar does however keep all other functions running including the altimeter, barometer, and compass
