Replace batteries on spf-40 model 2273

Hi You will need to have two screwdrivers , one to hold the one side steady whilst you unscrew the other side.

i would suggest you ask some one to hold the one screwdriver and watch will you undo the other screw.

Hi Debra, yours might be similar to my IronMan watch...... 4 small Philips head screws to remove then back comes away to reveal a sticker that has 2 clips either side, use a safety pin point to release the clips and the battery comes off with the sticker! The battery is placed with the total flat side upwards! Hope this helps!

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.

did u ever figure out how to get the retaining clip?

You have to dismantle your watch first.
Check the back of case- if there are visible screws- undo them and take caseback off. You should see the battery. Take it out, read the numbers on battery and replace with the same one.
If you can not find any screws on caseback- you have to undo screws from the dial side, get the movement out and then change the battery.
BE WARNED: if the watch must be opened from dial side, you can easily damage it as some particular skill is needed. Do it on your own risk.

Good luck

For all Casio watches go to www.casio.com select "Support" then "Manuals" then "Watches".
You will then be able to enter the 4 digit number in the square box to get the manual for your watch or module inside is actually what the instructions refer to.

The problem of changing functions automatically is called "Auto Display" and can be stopped and started in Sea-Pathfinder SPF-40 (modue 2273) by pressing the bottom left button for 3 seconds.

i had this problem with mine after a battery replacement. If you open your watch, and look behind the offending button, you'll notice there is a small arm that should fit behind the button. the jeweler that destroyed my O-ring during a battery replacement also failed to line these arms up on one side of the unit. i had to find a REALLY small screw driver and finagle the arm back under the button... Now it's working perfectly... except the whole not waterproof any more part....

Hope this helps.

Your Watch is in Auto or demo mode. Hold down the "Mode" button for 3 - 5 seconds and it will return to time keeping mode.

Cheers,
