I am trying to replace the battery in my watch; I've put the new battery in, but the watch has not restarted. What should I do next

could be the battery .. try taking the back off,take battery out and leave the battery out for 10 minuets ..then put it back in . this could help restart the charging cycle . if not then you'll need a new battery

I am assuming you are reading the battery charge correctly. If so you need a new rechargable battery. Special battery so it is a little expensive. Make sure the person knows it is a "rechargable battery" you want. A regular battery will not work properly or recharge.

Some watches have a "reset" button or combination of buttons that must be pushed to clear all the electronic registries on the watch's little computer after you replace the battery. You might try taking off the watch back and seeing if your watch has this requirement. Even then, it's not always a perfect solution. Last week, I replaced the battery in a watch that had been dead for some time. The watch appeared to come alive again when I put the new battery in, but when I pushed the reset pin (on this movement, it was on the watch movement itself, next to the battery), the entire watch went dead. Nothing I did would wake it up. I removed the battery, waited 30 seconds, then re-inserted the battery. Problem solved; the watch powered up, and I was able to set the time and access all functions again.
On some digital watches from the 1980s, after replacing the batteries, you were supposed to push and hold all the external buttons for a few seconds to reset the watch. I don't think manufacturers still make watches that respond to this, but it is easier to try than taking off the back and re-installing the battery.

Hi, Look on page 11 of your manual for the proper procedure to restart watch after a battery change, or complete discharge of capacitor system. If you don't have the manual, Try this link:

Take the four-digit module number from the back of the watch, enter it, and download a PDF of your watch setting-instructions/manual.
I hope this helps you. Thanks, Bill

mcdevito75 here, The Internal workings of all watches and clocks, Quartz and mechanical is called the movement. You may have a weak or even dead battery, even if the battery is new. If you"ve dropped your watch, got it water logged, you could have hurt the Quartz movement. It'll take special equiptment to check the Quartz movement to see if it"s burned out. I would try another battery or at least double check this batteries instalation in your watch. For more info, here is Casio"s contact number, 800-435-7732 9AM--5PM EST.

mcdevito75 here, You may need to start your watch by pressing the MODE button. Most quartz watches will stop once you"ve changed the battery, of course the possibility is there that the watch quartz has burnt out also. See a small watch repair shop in your area.

mcdevito75 here, I'm figureing you"ve changed the battery, Pressing the MODE button should re-start your watch. If you didn"t change the battery and your watch just stopped, try pressing the MODE or any button to re-start the watch. If nothing, change the battery and repeat the above instructions.

this video will show you were the spring goes next to battery

1) Take off white plastic cover so that the only metal cover is seen
2) Notice in upper right corner there is a "golden" pad - tiny one and in the metal cover there is an engraving AC. Use some needle like (conducting) object and connect this pin to metal cover (ground) - this will reset your watch.

This watch is a quartz watch and probably needs the battery replaced.
