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.

Immediately after you press (C) to return to the Timekeeping Mode, the mode hand will indicate the battery charge level. After a short while, the mode hand will indicate the current day of the week.

①

Good (high charge)

②

Good (medium charge)

Low Battery

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

The second hand jumps at two-second intervals.

All hands and the day indicator are stopped.

The table below shows guidelines for approximate charging times.

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, 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.

Press any button, perform a crown operation, or place the watch in a well-lit area to recover from power saving.
