How do you change the battery in Model 45/7012?

FIXYA volunteers usually recommend paying a jeweler to change the battery for a minimal cost, where the removed battery will let you identify and purhase a replacement battery cheaply.

Possibly a 394 for a different model.

Check with some jewelers and mall stores to see if they will replace it for you at a reasonable cost.

How to change the battery on Armitron Diamond Watch Model Y121E 3

After changing the battery press and hold all the buttons at the same time to reset this will make the watch and battery works properly so that the battery wont drain easily. I hope I have been helped you.

Google the model number for "manual" which if found will have instructions for replacing the battery or take it to some place like walmart who will open and replace it for you.

Most probably its battery problem. You can go to any reputed (Titan, Timex) watch showroom and get its battery replaced. They will change the battery immediately.

Don't get the battery replaced from the small watch repair shops. They don't have original batteries, so your battery will not last long.

Hope it helps. Don't forget to rate me. Thanks for using FixYa.

mcdevito75 here, Best Bet, look for a small watch repair shop in your area to cahnge the battery as any pressure on the display while changeing the battery on a Casio watch will break it.

Yep, here it is....SR920W

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.
