Astro Boy x G-Shock 60th Anniversary Watch

Technology: Backlights

Full EL backlights that illuminate the display with just a tilt of the wrist by 40 degrees from the horizontal position and some sense light and dark automatically to bright LED lights

To turn the auto light switch on and off

• In the Timekeeping Mode, hold down B for about three seconds to toggle the auto light switch on (auto light switch indicator displayed) or off (auto light switch indicator not displayed).
• The auto light switch indicator is on the display in all modes while the auto light switch is switched on.
• In order to protect against running down the battery, the auto light switch turns off automatically approximately six hours after you turn it on.

Tips

• Avoid wearing your G Shock watch on the inside of your wrist if you are using the auto light switch. Doing so can cause the auto light switch to operate when it is not needed which shortens battery life.
• Illumination may not work if your watch is more than 15 degrees above or below parallel. Make sure the back of your hand is parallel to the ground.

Illumination turns off automatically after a preset period of time. To increase this period, follow this procedure:

• Sometimes illumination can take up to one second to enable after your watch is turned to face you. This is normal and is not a malfunction with your auto light switch.
• You may notice a faint clicking sound when you shake your G Shock back and forth. This is caused by the mechanical operation of the auto light switch and is not a malfunction or a problem with your watch.

Cheers! (:

Technology: Solar Powered

Casio G-shock watches with solar technology, receive thermal and electrical energy that recharges the watch batteries through solar panels on the face of the watch.

A solar panel converts even weak illuminuation from fluorescent lighting into electric power. A rechargeable battery with a large power storage capacity supports stable operation of various functions with high electricity consumption. You never have to worry about the battery running down because it's a solar battery.
