If you haven't got instructions on how to do this, you can get
instructions from the Casio web site.

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

Select "support" and the "manuals",
watches;

Try the manual : - http://ftp.casio.co.jp/pub/world_manual/wat/en/qw2688.pdf
although, unless you're in North America, you probably won't get the signal the watch needs to synchronise.

Copy the manual from;

http://ftp.casio.co.jp/pub/world_manual/wat/en/qw2688.pdf

If DST is set to AUTO,time (DST ON-DST OFF) is corrected automatically when the watch is synchronized.
Synchronization period (Radiocontrol) from 00:00 until 06:00.
If you live in an area where atomic signal cannot be reached by the watch,you have to change DST-NORMAL and vv,manually,by going to WT (World Time) function and when your city (or the closest big one) appears on the display,press and keep pressed for 1-2sec the SET button.
DST mark will appear or disappear,accordingly.

On the solar charge watches, they use a chargeable Lithium battery. It is NOT an off the shelf regular battery! It is best to send the watch to the factory service rep in your area for a battery change.

In many of these models the battery is using solder contacts to the circuit board. The person changing the battery will require the original spec battery, and be equiped to do surface type soldering.

When working on this watch, the factory service will change the seals and do a pressure water resistance test. The regular corner watch service store is not equiped to do this type of testing.

Normaly, the battery in solar watches should last more than 5 years. Some are going past 10 years!

The general instructions for the for the 2608 and the 2688 are pretty much the same. However you can go to this link and type in 2688 for your module number and get specific instructions.
