After the watch receives the time calibration signal, it performs various calculations to determine the current time. These calculations can cause the time setting to be off by up to one second.
Why is the time as set by the time calibration signal one hour off?
This is because the watch is not making allowances for Daylight Saving Time (summertime). Change the watch’s DST setting* to “Auto DST”, and it will adjust the hour setting automatically. Note that you should turn off the DST setting if you are in an area where Daylight Saving Time (summer time) is not used.
* For models that do not have the “Auto DST” setting: DST setting can only be turned on/off manually.
Why is the time as set by the time calibration signal wrong?
Your Home City code setting is probably incorrect for your current location. Change your Home City code so it matches the time zone where you are currently located.
How is the accuracy of this watch?
Excellent. Since the watch automatically adjusts its time setting in accordance with a time calibration signal, you are always ensured of very accurate timekeeping.
Is there anything I can do to improve time calibration signal reception?
The following are guidelines for signal reception.
- Position the watch as shown in the following illustration, with its 12 o’clock side facing towards a window. Make sure there are no metal objects nearby.

- Near household appliances or office equipment, or a mobile phone
- Near a construction site, airport, or other sources of electrical noise

- Time calibration signal reception takes from two to five minutes, but in some cases it can take as long as 12 minutes. Take care that you do not perform any button operations or move the watch during this time.
