Is the battery on the G-Shock MT-G recharge either by motion or sun light?

It needs professional repair, before the seawater permanently damages the circuitry. Or you just buy a new one.

My watch was in the drawer for over a year and stopped working. I flashed my iphone torch directly on it for literally about 3 minutes and BRAVO it's working again.

Old watches have a spring which you must wind. Other watches have a battery which must be changed when depleted. The AUTOMATIC watches have to be worn because the mechanism acquires energy by the motion of the hand. Solar watches must be exposed to direct sunlight to recharge a battery inside the watch. While worn they must see the light occasionaly. If the watch is a solar one and you are not wearing it, do not store it in an opaque box, but in a place where it can receive light (from the sun or a light bulb.

Do you mean, you haven't been wearing that watch but to put it in the drawer for a long time?
If so, to recharge the battery, just put your watch outside or anywhere it can catch the sun ray or day light. After few hours or about a day, the battery has been re-charged and your watch will work.
If it still doesn't work after doing that, buy a new watch. Don't bother to repair the watch or to replace the Eco-Drive battery, because of the cost.

The rechargeable battery needs to be replaced in the watch, you need to take it to a jeweler to have a new one installed.

Hi,

An Eco-Drive does not need to be wound. It has a rechargeable battery in it that is recharged by light hitting the dial of the watch.

All Eco-Drives have to be allowed to get light on them to recharge the battery. If they are put in a drawer or covered all the time by shirt sleeves then the battery will drain and they will not work.

If the battery is completely drained then the battery will not be any good and will need replacing by a qualified watchmaker.

Try setting your watch under a light or in a sunny spot with the light shining on the dial. If in the sun light it should take a few hours to charge the battery. If under a light it can take more than 18 hours to fully charge the battery.

But if the charging does not hold then the battery is no longer good and requires replacement by a qualified watchmaker.

Hope this helps,

For sure you know EcoDrive watches are powered by light and all advertisements says: you will never have to change the battery. That's right - you will never have to change the battery, because there is no battery as we know. In your watch you have CAPACITOR, and it is the cell (sort of battery), recharging itself from the light consuming plate underneath the dial. Capacitor is not timeless, so, you have to replace it anyway. Find your nearest watch repair shop and ask for replacement.

Batterie model is Panasonic MT920. You can order a Citizen part no: 295-5600 who is a rechargable batterie for watch mouvement Miyota model BR10. That mouvement is use in Bulova motion quartz, Invicta automatic and Citizen eco drive.

I just replaced mine, same model, there's only 1 battery in it.

My watch had the same problem and i could never figure out what it was so i just lived with it for a couple of years. then, just recently even when my watch was getting plenty of sun the battery would die in the evening and shut off at night. so i replaced the battery and evrything works great. even the light which leads me to believe the solar panel is just a gimmick. i have an old g-shock watch that i bought in 1989 and it still works and is on the origional battery. my gw 300 is about 5 years old and needed a battery. i guess 5 years on a battery is prety good but i would rather have it last for 19 years like my old one.
