Power Source
The battery used in this watch is a special secondary battery, which is different from ordinary
batteries.
Unlike an ordinary silver oxide battery, the secondary battery does not require periodic
replacement.
The capacity or charging efficiency may gradually lower due to long-term use or operating
environment.
In addition, long-term use may shorten the charge duration due to wear, contamination, lubricant
deterioration of mechanical parts, etc. Request repair when the performance lowers.

WARNING
■ Notes on replacing the secondary battery
• Do not remove the secondary battery from the watch.
Replacement of the secondary battery requires professional knowledge and skill.
Please ask the retailer from whom the watch was purchased for replacement of the
secondary battery.
• Installation of an ordinary silver oxide battery can generate heat that can cause
bursting and ignition.

There is no need to worry about damage caused by overcharging no matter how much the
secondary battery is charged in excess of the “time required for fully charging the watch.”
