Remaining Charge and Dead Battery
●
You can determine if the charge level is low by
checking the hand movement. Functions
become disabled as battery power goes low.
Important!
Should the battery go low or go dead,
●
expose the face (solar panel) to light as
soon as possible.
Note
Exposing the watch face to light after
●
the battery goes dead will cause the
second hand to revolve
counterclockwise until it stops at
second 57. This indicates charging
has started.
Low Battery Power
The second hand jumps at two-second
intervals.

Power Saving

Leaving the watch in a dark location for about
one hour between the hours of 10 p.m. and
5:50 a.m. will cause the second hand to stop
(hand sleep), and the watch to enter Level 1
power saving. If the watch is left in this
condition for six or seven days, all hands will
stop and the watch will enter Level 2 power
saving.
Level 1 :
Basic timekeeping functions are operational.
Level 2 :
Only the day indicator is operational.
Note
Note that the watch also may enter the
●
power saving state if its face is blocked
from light by your sleeve while you are
wearing it.

●
Operation
To recover from power saving, perform one of
the following operations: press (A), perform a
crown operation, or place the watch in a well-
