8. About the Eco Drive Rechargeable Battery
This watch uses the rechargeable battery, which does not have to be periodically replaced
due to repeated charging and discharging, unlike ordinary batteries.
However, certain maintenance, such as water testing and gasket checks should be performed
at regular intervals. The requirements will vary by model and features.
Caution
Never use a battery other than the Eco Drive Manganese Titanium rechargeable battery used
in this watch.
Installing a battery other than the original Eco Drive Manganese Titanium Rechargeable
battery may result in overcharging of the movement causing it to burst, which could result
in damage to the watch and even to the human body.
