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.

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.

Required Charging Time for 1-day Use

Time Required to Achieve Next Charge Level

• Sunny day, outdoors (50,000 lux)

• Sunny day, near a window (10,000 lux)

• Overcast day, near a window (5,000 lux)

• Indoor fluorescent lighting (500 lux)

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.

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