7 Charging the battery

This watch has a battery which is charged by exposing the dial to light such as direct sunlight or fluorescent lamps.

To obtain the best performance

• Expose the dial to direct sunlight for several hours at least once a month.

• After taking off the watch, put it where the dial is exposed to bright light, such as by a window.

• Before storing the watch in a dark place for an extended period of time, fully charge the battery.

When the watch is covered with long sleeves, for example, the battery may not be charged sufficiently. Try to keep the watch exposed to light even when wearing the watch.

Charging the battery

Do not charge the battery at a high temperature (about 50˚C/122˚F or higher).

7 When the battery becomes short of power—Insufficient charge

warning function

• After the battery is charged for a while, the second hand will move normally.

• If you have not charged the battery for four days or more since the warning movement began, the battery will run out and the watch will stop.

When the battery becomes short of power, the second hand moves once every two seconds—insufficient charge warning function. Charge the battery by exposing the dial to light.

7 Charging time

Below are the approximate values for when exposing the dial to light continuously. Use the table below only as a reference.

Charging the battery

This watch has the “Eco-Drive” system, which converts light into electrical energy using the solar cell beneath the dial. The system makes you free from care of battery replacement and is environment-friendly as no battery disposal is required.

After the battery is fully charged, charging automatically stops to prevent overcharging, which may damage the battery, or affect the accuracy, functions, and performance of the watch.
