just bring your casio watch to casio service center, i'm sure they have what you are lookin for.

Same problem with my SPF-40, module 2273, after a small helical compression spring, silver color, fell out. I could not determine where it is suppose to be located. It could be the barometric reference spring for sensing the barometric pressure.

Hi Harry,

Your Module number is 2271.
1. To set the time, press and hold button A (left top) until Seconds digits start to flash.
2. Press button D (lower left) to move flashing in the following sequence to change other setting:
Seconds >> Hour >> Minutes >> 12/24 Hour Format >> Year >> Month >> Day >> (Then back to Seconds)
3. While a setting is flashing, use E (+) (bottom right) and B (-) (top right) to change it.
Note: When in the 12/24 Hour Mode, use E and B to toggle between 12-Hour and 24-Hour Mode.
4. Press buton A to exit setting screen.
Your time should now be set.

This should give you all the info you need to operate all the functions of your watch. Thanks.

Casio battery changes are quite tricky.If you look closely at the watch module there is a place for the battery and a v-small depression usually circular on the silver module .There will be the letters AC in small writing.You need to touch the depression AC and the battery at the same time with a conductive tweezers.This shorts the module and re sets the watch.Make sure any seals go back in to protect from water/dust.

Yes, go to "www.casiowatches.shriro.com.au/" where you should be able to find the information you need.

Click on "service agents" to find the address of your nearest agent.

The safest option is to take it to a watch shop and ask them to change it for you.

While removing the back and replacing the battery,(assuming that is has a similar back to mine, which is the same make),is not too difficult, it can sometimes cause problems and since the charge for this is quite small, it is not worth taking any risk is getting it wrong. (Particularly difficult is making sure that the seal is properly made).

Considering the cost of you watch I would advise against doing it yourself.

here: Amazon com Energizer 395 399 Silver Oxide 5 Batteries SR927W SR927SW . I hope I have helped. Cheers

you can go to this link and in the upper right corner type in the model number not the module number (there are instructions for finding the model number if you don't know it) I found a band for a watch that is over 8 years old on here.
