integrated into the face of the watch, and
power is generated whenever the face is
exposed to light.
●Charging the Watch
When you are not wearing the watch, put it in
a location where it is exposed to bright light.
While you are wearing the watch, make sure
that its face (solar panel) is not blocked from
the light by the sleeve of your clothing. Power
generation efficiency is reduced even when
the face of the watch is blocked only partially.
NOYES
Important!
●Depending on light intensity and local
conditions, the watch may become hot
to the touch when exposed to light for
charging. Take care to avoid burn
injury after charging. Also, avoid
charging the watch under high-
temperature conditions like the ones
described below.

time adjustment during the previous
day while connection with a phone is
being used, it will automatically try to
receive a time calibration signal.
Note
●Areas where time calibration signal
reception is supported are limited.
When the watch in an area where time
calibration signal reception is not
possible, connect with a phone to
adjust time and day settings.
lTime Calibration Signal Reception

crown operations.
