This watch can be set to the

precise local time by just one

button operation anywhere in

the world.

This watch operates by solar

charging.

This watch automatically

adjusts the time in accordance

with action patterns during

use.

Expose the dial to light to

charge the watch.

Once fully charged, the watch

runs for approximately six

months.

When the energy stored in the

watch runs out completely, it

takes time to fully charge the

watch, so please keep in mind

to charge the watch regularly.

→ How to charge the watch　P.37

→ Standard charging time　P.37

When the watch has sensed

sufficient brightness under

an open sky, it automatically

receives GPS signals from GPS

satellites. This function enables

the watch to automatically

adjust the time precisely even

while you are using the watch.

Precautions on time zone adjustment

If the time zone is adjusted near a time zone boundary, the time of the adjacent time

zone may be displayed.

In some areas the boundaries observed by the watch may not exactly correlate to

the actual time zone markers on the land.

This does not indicate a malfunction.

In this case, set the time zone in the manual time zone setting mode.



When the time zone is adjusted while traveling on land, avoid time zone boundaries

to carry out time zone adjustment in the representative cities in the time zone

whenever possible.

In addition, when the watch is used near time zone boundaries, make sure to check

the time zone setting, and manually set the time zone as necessary.
