Environmentally friendly energy with TOUGH SOLAR®
The integrated solar technology rounds off the range of robust G-SHOCK watches: As an independent and environmentally friendly feature, TOUGH SOLAR® models are equipped with an inconspicuous solar cell on the face that stores energy from sunlight, ensuring the watch’s power supply. "Surplus" energy is stored in a rechargeable battery which, if necessary, can be released again when the watch is situated in the dark, making the classic battery change a thing of the past. The battery is charged automatically and does not require manual activation. If the watch is in the dark for a longer amount of time it goes into energy-saving mode independently. This means that it has a darkness reserve of up to 24 months.
Stable operation of high-load functions
A solar panel that generates power from even a weak light source combined with a large-capacity rechargeable battery to drive multiple power-hungry functions reliably.
The area required for the LCD, dial printing and other elements is calculated precisely to allow installation of a highly resilient film-like solar panel on the dial.
Six solar cells, connected in series, all receive the same amount of light.
