How to operate module 5125

Short steps in our words. The buttons are lettered as in Casio's operation guide, where each task's page is given.

Set the time, day and day of the week

  1. Wait until the second hand reaches 12 o'clock, then pull the crown out to the second click to stop it.
  2. Turn the crown to set the hands, going four or five minutes past the time you want and then turning back to it.
  3. Push the crown back in on a time signal to restart the watch.
  4. To set the day, pull the crown out to the first click and turn it counterclockwise.
  5. To set the day of the week, turn the crown clockwise at the same click, then push it back in.

Good to know

Do not set the day or day of the week between 9:00 p.m. and 5:00 a.m., or it may not change over the next day.

If the crown screws down, unscrew it before pulling it out and screw it back in fully afterwards; the watch is not water resistant while it is loose.
