about two minutes after pulling out the

Day Indicator Movement

●
seconds for the day indicator to change
after timekeeping reaches midnight.
The day may not be indicated correctly
●
while the watch's crown is pulled out.

Charging

This watch runs on power supplied from a
rechargeable (secondary) battery that is
charged by a solar panel. The solar panel is
integrated into the face of the watch, and
power is generated whenever the face is
exposed to light.
●
When you are not wearing the watch, put it in
a location where it is exposed to bright light.
Day indicator
While you are wearing the watch, make sure
that its face (solar panel) is not blocked from
30
light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
Charging the Watch

creates the risk of burn injury and
damage to internal watch
components.
