The rechargeable battery used in this watch is a clean energy battery
that incorporates no toxic substance such as mercury inside. The
secondary battery has no need of periodical replacement because it is
capable of repeated charging and discharging.
<Remark>
As explained above, LV.1 indicates the range from condition (1) that the battery
is almost fully charged and the watch can be used for diving sufficiently to
condition (9) that the watch can be used for at least "one diving about one hour
long" and NG appears soon. Accordingly, the condition of LV.1 is explained as
the condition that "the watch can be used for one diving about one hour long" on
the instruction manual (explanation of the charge level indication), considering
the safety and assuming the worst condition.
