This watch can be set to the precise current time by automatically receiving GPS signals by exposure to bright light
outdoors under an open sky to adjust the time.
In addition, when the watch is concealed under a sleeve and the dial is not exposed to sufficient light even if outdoors
under an open sky, the watch stores the time of the previous successful manual time adjustment (or time zone
adjustment), and automatically starts time adjustment at the same time.
* In a place without good visibility, GPS signals cannot be received. → Place where GPS signals can be easily received/Place where GPS signals cannot be received
* If the energy is sufficiently charged, automatic reception will be performed every day.
* The automatic time adjustment is performed at most twice per day (At the time of sensing light, and at the time of previous successful manual time adjustment, it is performed
maximum once for each). Even if the reception fails, it may be performed one more time, according to the conditions.
* Since only automatic time adjustment by sensing light will be performed under factory default settings, before using the watch for the first time, please succeed the manual time
adjustment during the time zone when you will normally stay for a long time under the open sky where it is easy to receive signals.
* The time zone is not adjusted in the automatic time adjustment.
< When it is difficult to expose to light sufficiently >
Even if outdoors under an open sky, when the watch is concealed under a sleeve in winter time, etc., in an area where the daylight hours are short, or
when the watch is not likely to be exposed to sufficient light for a long time due to bad weather, the watch is designed to allow for automatic time reception
at the time when the manual time adjustment was successful the last time.
When the watch is exposed to the operating environment above, automatic time adjustment is likely to be successful by making manual time adjustment
successful in time periods where the watch is frequently used in a place where GPS signals can be easily received under an open sky.
→ How to manually adjust the time
However, as the watch judges to start automatic time adjustment taking into consideration the following conditions, the watch does not necessarily start
automatic time adjustment by exposure to bright light or at the time when the manual time adjustment was successful the last time.

Charging status
•
Past reception status
* When the energy level is “low” or when in-flight mode (
) is set, automatic time adjustment does not work.
When the energy level is “low”, expose the watch to light to charge it.
* When the energy is reduced, the period for which automatic time adjustment is not performed becomes longer. Keep in mind to charge the watch regularly.
* If the time zone adjustment or manual time adjustment is performed before the automatic time adjustment is started, the automatic time adjustment is not performed on that day.
