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 the watch’s current charge level by checking the Battery level indicator.

1.Hold down (A) for about two seconds.

This will cause the watch to enter the Calendar Mode.

2.Press (D).

This will cause the Battery level indicator to show the current charge level.

Low Battery

Good (medium charge)

Good (high charge)

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.

Charging Times Required for 1 Day of Operation

Leaving the watch in a dark location for about one hour between the hours of 10 p.m. and 6 a.m. will cause the second hand to stop, 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 at 12 o’clock and the watch will enter Level 2 power saving.
