POWER SOURCE (Rechargeable battery)

English

This watch requires no periodic battery replacement as it is powered by the

 

 

exclusive rechargeable battery, which is completely different from conventional

 

batteries for watches.

 

This exclusive rechargeable battery is an environmentally friendly, clean energy

 

storage device.

CAUTION

Never install a silver oxide battery for conventional watches in place of the rechargeable battery, which can generate heat that can cause bursting or ignition.

NOTES ON OVERHAUL

The watch is a precision device. If the parts run short of oil or get worn out, the watch may stop its operation or lose time. We recommend you have the watch overhauled periodically to keep it running accurately.
