• 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.”

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.
