How can I get the hands on my G-Shock watch to move when trying to set the time to be in sink with the digital part

I had a casio and the method was; press the mode button until the display says "HS", then press the 2 or 4 o'clock buttons to adjust the hands to match the digital time; then press mode button until normal operation is achieved.

My watch was a different model to yours, so if this does not work, then you can get
instructions from the Casio web site.

Go to the casio web site "casio.com".

Select "support" and the "manuals",

Select "watch manual archive"

Read the number of the back of your watch and enter it into the search box
