Is time calibration by GPS supported?
Yes. However, the calibration operation is manual and regular automatic calibration is not performed.
GPS information is acquired for your current location and the time is calibrated only when manual calibration is performed. After that, the time setting will gradually become out of sync.
You will need to perform manual calibration as required.
Note that GPS time calibration is not necessary if you use the watch in a way that it normally communicates with a phone because the watch will automatically calibrate its time setting with that of the phone.

GPS Time Calibration Procedure
  1. Select any CASIO watch face.
  2. Go to the setting screen of the selected watch face.
  3. On the list of settings, select "GPS Time Calibration" and then follow the instructions that appear on the screen.

* Not supported by the WSD-F10.
