Pow er sou rce
The battery used in this watch is a special secondary battery, which is totally dierent from ordinary silver oxide batteries.
Unlike other disposable batteries such as dry-cell batteries or button cells, this secondary battery can be used over and
over again by repeating the cycles of discharging and recharging.
However, for various reasons such as long-term use or usage conditions, the capacity or recharging eciency of the
secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the eciency of the secondary battery decreases, have the watch repaired.
■ Remarks on replacing the secondary bat tery
・Donot remove the secondary batter yyour self.
・Replacementof the se condarybatter y re quires prof essional
