G-Shock's popular model GW-6900KG battery replacement method will be released.
The life of the battery of G-Shock is not one year, two years, but I feel like it has more than five years, but if the light of the backlight becomes weaker than before because it immediately goes crazy even if the watch is set, it may be a sign of battery replacement.
When I examined the cost of replacing the battery of GW-6900KG at Casio, the home of G-Shock, it was 3240 yen including tax.
It seems that THE CASIO's bring-in counter will support battery replacement in about 60 minutes.
If it is 3240 yen, I feel that it is relatively cheap, but if I can change the battery of G-Shock by myself, I can fix it for around 100 yen to 1000 yen.
I do not know the capacity and quality of the battery to be used outside the regular store, but I feel that there is no problem at all.
However, in the case of a regular store, I think that it will also do waterproof check, so if you want perfection such as waterproof function, it is more reliable to have repaired at a regular store.
So if you want to repair yourself cheaply even a little, I think that you can refer to it.
The tools used can be substituted for the things in the home, but the drivers used are as follows.

There was a rubber waterproof on the outer periphery where the plate was removed.
If you want to change the battery, you do not have to remove it as it is.
It is said that it is good to paint grease when opening because this rubber deteriorates over time when using G-Shock for many years if it says to the person of the pass.

There is "AC" and "-" in the silver part around the battery, let's do the work to close the back cover after shorting for 2 seconds.
