Clean the contacts. Get the sharp needle and scrape both contacts. If it does not work, you need a watchmakers help. Rate me, plz.

MTG 900 SAYING "CHARGE" AND I'VE BEEN PUTTING


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.

I have an old Casio watch 863 SDB-500W, I have just change the battery . Light is working but nothing is display. How to reset it ?


To reset the watch, you need to 'short' the reset point with the battery. To do this, with the watch face down and the back removed the 'Reset' point is in the bottom right hand corner (a gold-coloured contact point). Use a pair of metal tweezers or an unbent paper-clip (anything as long as it's metal and will touch the reset point and the back of the battery at the same time). Maintain contact for about 5 seconds and you should get the display back.
I've just changed the battery in my SDB 500W and the above method worked. I did lose the audible 'beep' though and I'm currently on the net trying to find how to get it back. That's how I found your question... :)

What is the main internal assembly of the Casio forester watch called? Replacing the battery does not work.


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.

How to restart my casio module no 2271 watch


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.

I put in new battery using Casio instructions but still does not work. Touched battery and ac with tweezers for a few seconds, nothing happened?


Make sure your new battery is not flat and on full power. Sometimes batteries are not fully charged as they discharge over the time and as they are stocked in large quantities, some of them get discharged even they are sold as brand new.
When replacing battery in your watch, make sure you keep the right polarity. Plus and minus must match appropriate contacts. After replacement connect AC and plus side of the battery at once for 2-3 seconds - this will reactivate watch and you will need to set the watch manually.
If you did all this and your watch don't work at all, there is some fault in watch mechanics and you have to look for watchmakers help.

I have a Casio DBC-60. I changed the battery because was not working for long time, but the watch stil is not working


This is an old problem, but maybe this will help someone changing a battery on a Casio. Many Casio watches must be "zeroed out" by putting an pointed tweezers between the back of the battery and the AC terminal off to the side of the battery. On my old Casio Telememo 50, the AC terminal is in a very small hole just above the battery. On the Baby G force, it was in a wider opening, way at the edge of the watch. It has something to do with resetting the watches circuitry so it will operate again. Good luck!

Use this link to read Direct Casio manual:

http://ftp.casio.co.jp/pub/world_manual/wat/en/qw3747.pdf

I suggest you may need to wait till the first signal is received by watch.
If all this doesn't work, then check the battery condition- it may be underpowered and need replacement. Eve if your watch is brand new, the battery may be few years old.

Do not forget to rate, please.

Please help me to replace battery on my casio F-91W


This reset trick works with other Casio Alarm Chrono digital watches, such as my old Model W-720, similar to your F91-W. After the new lithium coil cell is installed and secured with the spring clip, the watch may show random segments in the LCD display or may simply be blank. Insert a sewing needle, paper clip, or blade of a small jeweler's screwdriver into the hole on the back of the movement stamped "AC" (All Clear) to momentarily connect the gold plated contact at the bottom of the hole to the stainless steel battery clip. The battery clip in most such Casio watches is connected to the "+" terminal of the coin cell. This will reset the CMOS chip and it should start up with the watch displaying 12:00 and the date at 1-1. Then, use the control buttons to set the time and date in the normal fashion.
