I HAVE A CASIO WAVECEPTOR ATOMIC WATCH AND IT DID NOT CHANGE FROM DAYLIGHT SAVINGS TIME BACK TO EASTERN TIME. I FIGURED HOW TO SET THE HANDS BUT DIGITAL PART DIDN'T CHANGE. SEVERAL DAYS LATER THE DIGITAL TIME CORRECTED ITSELF BUT THE HANDS CHANGED BACK AN HOUR AND I CANNOT FIGURE HOW TO RESET THE HANDS BACK AHEAD AN HOUR SO BOTH SHOW SAME TIME.

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

If your watch is exactly an hour out, then you need to set the daylight saving time (DST) via the mode button.

If this is not the case, then I cannot help you.

~Good luck

If you cannot find the automatic way of setting the hands, you can manually reset the analogue hands by pressing the mode button until you reach the "HS" mode and using the 2 or 4 o'clock buttons to adjust the hands.

I have one of these, and look for the manual on the 'Net every time DST changes, and eventually figure it out. Here's how: (1) Hold down the ALM/SET button until you get past the alarm setting and you see 24H or 12H. (2) Step through the settings by pushing the ALM/SET button, changing each as desired by pressing the +/CYCLE button. Eventually you'll wind up with the time zone indication flashing (it's really tiny, and appears just below the time indication). Press the +/CYCLE until you get to the desired time zone. (3) After the screen quits flashing, press the -/DST button to get the desired setting. I hope this helps, and that I can find this post again next time change!

I don't have wvq 202hdu but I have a waveceptor that had the same problem. After not being able to find a solution online, I went back and started playing with it and I figured it out on my wva-430a. Hopefully my instruction helps:

The problem is that the daylight saving time is set to ON (or maybe OFF) whereas it has to be set on Automatic (A). To change that on my wva-430a, I held the "Adjust/Display" button for three seconds. It showed "US 60" for me. Then I used the "Mode/Select" button to go to the next screen which shows CHI for Chicago (Central Time). Here you have to choose the city that corresponds to your time zone. Again by pressing "Mode/Select" it took me to the next screen which was the daylight saving option. The choices were ON/OF/A that could be cycled by pressing "Receiving/Set+" button. Set it to "A" for automatic. Then press Adjust/Display to see the last option for 12H/24H setting. Press Adjust/Display one more time to go out of the settings menu. Your watch should adjust itself immediately.
