A solar cell underneath the dial converts any
form of light into electrical energy to power the
watch and the power is stored in a secondary
battery. Once fully charged, the watch
continues to run for approximately six months.
The movement of the second hand indicates that
the battery should be charged.
The Power Save mode can be activated in order
to reduce unnecessary energy consumption when
the watch is left without an adequate light source.
The watch can be set to local time in a diff erent
time zone from Japan Standard Time by selecting
a time zone.
When the hand positions deviate to display incorrect
time as a result of infl uence of various external
sources such as magnetic source, the watch
automatically corrects the hand alignment itself.
