disposable batteries such as dry-cell batteries or button cells, this rechargeable battery can be
used over and over again by repeating the cycles of discharging and recharging.
The capacity or recharging efficiency of the rechargeable battery may gradually deteriorate for
various reasons such as long-term use or usage conditions. Worn or contaminated mechanical
parts or degraded oils may also shorten recharging cycles. If the efficiency of the rechargeable
battery decreases, it is necessary to have the watch repaired.
