Reboots of anything can be hit or miss, but Casio hit this one out of the park with the GW6900 G-Shock. A twist on the iconic DW6900, the new kid on the block features non-stop, tough solar power and self-adjusting multi-band 6 atomic timekeeping. The non-stop solar tech is easy to figure out, but in case you’re unfamiliar with atomic timekeeping then here’s the lowdown from Casio.

Self-Adjusting Multi-Band 6 Atomic Timekeeping – Compatible with all six transmission stations worldwide, Multi-Band 6 is a radio-control system built to receive time calibration signals from up to six transmission stations: two in Japan and one each in North America, the United Kingdom and Germany, plus the new station in China.

Through a miniaturized, shock-resistant, highly sensitive amorphous antenna and large-capacity, power-saving LSI, stable operation of watch functions including 6-station radio wave reception are achieved. With Casio’s Atomic Timekeeping Technology, you will always have ultimate precision.

All three colors are available now for $130.
