Power Source; After-Sales Service - Seiko C-16 Instructions Manual

Power source
The battery used in this watch is a special secondary battery, which is totally diff erent 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 effi ciency of the
secondary battery may gradually deteriorate. Worn or contaminated mechanical parts or degraded oils may also shorten
recharging cycles. If the effi ciency of the secondary battery decreases, have the watch repaired.

knowledge and skill. Please ask the retailer from whom the watch
