Set the time and date
- In the Timekeeping Mode, unscrew the crown by turning it towards you and pull it out to the second click: the second hand points to the Home City time zone.
- Hold C for at least one second: the second hand moves to 12 o'clock.
- Rotate the crown to set the hour and minutes.
- Press C, then rotate the crown to move the second hand to the tens digit of the year; press C again and set the ones digit the same way.
- Press C and rotate the crown to set the month (read on the second hand).
- Press C: the mode hand moves slightly. Rotate the crown to set the day.
- On a time signal at the top of a minute, push the crown back in and screw it down.
Good to know
Set the time by hand when the watch cannot connect with a phone (CASIO WATCHES app); select the Home City first.
To receive the time signal now, unpair the watch from any phone, put it by a window, and in the Timekeeping Mode hold D for at least 0.5 seconds until the second hand points to RC. It takes about two to 10 minutes, up to 20.
Press C after the day to go back to the hour and minutes.
Changing the day makes the mode hand spin for a while; this is normal.
