Might have water damage but power is off and won't turn on

Can u change the battery and see if that was the issue? If so and its not the battery you could open the watch on visibly check for black/scourched marks that would indicate that (probably the water) something has shorted said part(s) with the marks. If you see nothing strange then its time to use a meter to test parts.

How to change the battery on a Large Square Digital Ebtek watch?

You will either find a very small lip that accepts a prying tool or you may see some indentations for a caseback wrench to unscrew it. Any jeweler or watch shop (including Sears) will change the battery for less than $8 and ensure that no damage is done and that the gasket that provides water resistance is replaced (insist that they do!). DO NOT reuse the gasket even if it looks undamaged. It will not keep water out if it is reused.

Watch doesn't talk anymore

If the battery is not visible by removing the back then this is not a battery change that I recommend for the layperson. I suggest taking this to a watchmaker or technician. This is because the battery powering the circuit board for sound maybe under the circuit board and not easily accessible without removing the movement and separating the circuit board from the movement. Also you should know that these sound boards are sensative and can easily be damaged.

Start buttons don't work after battery change Adidas Sports Timer

You will have to open your watch, because the contacts or contact springs are not stiff enough, so, you need to make them stiffer.
Do as follows:
1) Open your watch caseback
2) Extract the movement (carefully and using tweezers), do not touch dial with fingers,
3)Take small brush and lighter fluid (ZIPPO) and clean all pushbuttons in case from inside and out pushing them rapidly, then use dust blower to dry the fluid out,
4)On the movement you will see contacts corresponding to each pushbutton on the case. Use needle or sharp metal pin to clean (scrape) off any visible residue from these contacts till they are shiny.
5)Pull all contacts on movement sligtly outwards using tweezers but be careful not to brake. This will make them stiffer.
6)Reassemble the watch and the problem should be sorted.
Do not forget to rate, please.

Digital watch is stuck in chronometer mode

If this has occurred since a battery change then you my need to earth the movement by simply touching a wire from the battery to a hole with brass visible with AC written alongside (this is the case for a casio) alternatively, if not after a battery change....

Remove battery for 10 minutes and stick back in - if the buttons work then hey presto - if not - chuck it in the bin!

After changing the battery nothing can be changed, no function possible and"open" remains written on the display, the type of the battery is clt 1616

The battery is CTL 1616 and I had the same occurance when I opened up my model Casio model 3043. I needed to use the battery to test my model 2767 and find out if a new battery would bring it back to life (yes, it still lives). After replacing the battey back into my 3043, I jumped the (ac) to (-) and at first the watch would indicate all was well but then it would revert back to "open". I tried over and over to try and get the "open" display to clear but I was not successful. I then thought to go ahead and replace the back on the case to see if the three contact springs would change the display and sure enough, "open" no longer was in the display. The watch works perfectly as before. As for the 2767, as soon as I jumped the (ac) to (-) the "open" display went away. There is only one spring contact to the back case on the 2767 model. Unfortunately I do have an extra spring that fell out when I opened it up and I have no clue as to where it goes. I have not found anyone who can help me on the location for the shorter spring. Any advice would be most helpful.

I just replace the battery for a casio watch 2315 but it still does not work

Hi, I just encountered the same problem today as I was changing the battery and I found the solution. First make sure when you are changing the battery that the watch stem is pulled out; then after the battery has been replaced, and before you put the gasket and back on you will need to "reset" or "hotwire" the battery are going to likely need a magnifying glass to find a tiny ac symbol on the back of the watch (without the back cover replaced)...just next to the ac symbol is a tiny hole. Take a piece of wire, or in my case I used an unfolded paper clip, and put one end of the wire in the hole and the other end on the back of the battery (the +/positive side should be facing up). Leave the wire in contact with the ac/battery for 5 seconds, then remove. Next replace the rubber gasket, then the back and the screws. Lastly, push in the watch stem. Your watch should now work. I found out through considerable research that almost all digital watches will need that "hotwiring" step performed after the battery is replaced.

Battery Replacement

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
