Charging the Watch

The face of the watch is a solar panel that generates power from light. The generated power charges a built-in rechargeable battery, which powers watch operations. The watch charges whenever it is exposed to light.

Charging Guide

Important!

ξKeep the watch in an area normally exposed to bright light when storing it for long periods. This helps to ensure that power does not run down.

ξStoring the watch for long periods in an area where there is no light or wearing it in such a way that it is blocked from exposure to light can cause power to run down. Make sure that the watch is exposed to bright light whenever possible.

Warning!

Leaving the watch in bright light for charging can cause it to become quite hot. Take care when handling the watch to avoid burn injury. The watch can become particularly hot when exposed to the following conditions for long periods.

ξOn the dashboard of a car parked in direct sunlight

ξToo close to an incandescent lamp

ξUnder direct sunlight

Power Levels

You can get an idea of the watch’s power level by observing the movement of the x Second Hand.

ξ If the x Second Hand is moving normally at one-second intervals, power is at Level 1.

ξIf the x Second Hand is moving at two-second intervals, power is at Level 2,

which is quite low (Low battery alert). Expose the watch to light as soon as possible so it can charge.

ξWhen power drops to Level 3, all settings (including timekeeping) will be cleared. Recharging the battery will reset all settings to their initial factory defaults, so you will need to configure settings again.

ξWhen the watch is at Level 3, exposing it to light for a while will cause the x Second Hand to move to the position of second 57. This indicates that charging has started.

Power Recovery Mode

The watch is designed to go into a power recovery mode that stops hand operation temporarily whenever power suddenly drops below a certain level due to continuous signal reception, or overuse of the alarm tone over a short period or other operations over a short period. Note that all operations are disabled while the watch is in the power recovery mode.

The hands will move to the correct positions and the watch will resume normal operation after power recovers. Putting the watch in a location where it is exposed to light will help power to recover sooner.

Power Saving

Power Saving enters a sleep state automatically whenever the watch is left for a certain period in an area where it is dark. The table below shows how watch functions are affected by Power Saving.

Radio Controlled Atomic Timekeeping

This watch receives a time calibration signal and updates its time setting accordingly. However, when using the watch outside of areas covered by time calibration signals, you will have to adjust the settings manually as required. See “Confi guring Current Time and Date Settings Manually” (page E-28) for more information.

This section explains how the watch updates its time settings when the city code selected as the Home City is in Japan, North America, Europe, or China, and is one that supports time calibration signal reception.

If your Home City Code setting is this:

The watch can receive the signal from the transmitter

Important!

ξThe areas covered by HONOLULU (HNL) and ANCHORAGE (ANC) are quite far from the calibration signal transmitters, so certain conditions may cause reception problems.
