• The power reserve indicator provides only a general guideline of the duration within which
the watch keeps operating without needing to be charged.
• When the power reserve indicator indicates Low level, the second hand moves at two-
second intervals, and will stop within 48 hours.
• If the watch is charged by exposing it to strong light such as sunlight, the power reserve
indicator may not show the remaining power reserve amount properly. Make sure to charge
the watch sufficiently by referring to ”GUIDELINE OF CHARGING TIME/ACCURACY.” (P.25)

GUIDELINE OF CHARGING TIME/ACCURACY
A: Time to charge 1 day of power
B: Time required for steady operation
C: Time required for full charge
◆ The watch operates while
charging electricity by
converting light received on
the dial to electrical energy.
It cannot properly operate
unless the remaining energy
is sufficient. Place or store the
watch in a location receiving
light etc., to sufficiently charge
electricity.
• When the watch is
stopped or the second
hand starts moving
at 2-second intervals,
charge the watch by
exposing it to light.
•
The time required for
charging the watch
varies depending on the
calibres. Check the calibre
of your watch engraved
on the back cover.
• It is recommended
that the watch be
charged for as long as
the charging time "B"
to assure the stable
movement of the
watch.
