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 light by the sleeve of your clothing. Power generation efficiency is reduced even when the face of the watch is blocked only partially.

You can determine if the charge level is low by checking the hand movement. Functions become disabled as battery power goes low.

Low Battery Power

The second hand jumps at two-second intervals.

Dead Battery

All hands and the day indicator are stopped.

The table below shows guidelines for approximate charging times.

If the watch is not moved for about one hour, the connection with your phone will be terminated and the watch will enter Level 1 power saving.

Also, leaving the watch in a dark location for about one hour between the hours of 9 p.m. and 6 a.m. will cause the second hand to stop, and the watch will enter Level 2 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 3 power saving.

• Use one of the operations below to exit power saving.

• To go from Level 2 or Level 3 power saving to Level 1 power saving, place the watch in a brightly lit location.
