    I have replaced the battery in my Polar S120 and now have a string of meaningless symbols along the bottom of the screen and a line across the top. None of the buttons works. How do I reset it to function?

    can not reset watch so that backlight works

    I have the same problem with restarting or resetting after battery replacement in two of my casio digital watches (1) casio W-740 and (2) casio SKX-1000. It seams it may be different with different models. Both these have the AC engraving on the inner metal case, but I can't work out what I need to short it across to restart it. Any ideas anyone?

    I followed the advice dated 4/22/2008, below, and restarted my Casio Forester, module  #2147.  The directions are also located on the inside of the back of the watch.

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.

Changing batteries on a Casio G-Shock Cockpit watch

yes. wrong battery possibly...
395/399 = SR927SW/SR927W

The 395 is a lower power output but same voltage (1.5v). The power spike of shorting might have caused a spike in the watch electronics.. make sure they are right polarity too. These batteries are not high current items, but maintain their voltage over the 5+ year lifespan. The S and SW are basically interchangable except for the higher amerage output.

Restarting a Casio 4735 after battery change

Shortcut battery with AC contact. AC can be found on the sides of watch movement(very tiny). You have to use pointed tweezers: one end on battery+, another on AC contact for three secs.
this video is only an example as to what to do hope this helps you..

Changed battery .A square piece of metal the size of match head fell out. No alarm or light, casio forester FT200

mcdevito75 here, Of couse without the watch and piece of metal that fell out it"s very hard to say. Most likely it was part of the lock-down tab to keep the battery in place, in any event don"t lose that piece of metal. If your casio is working ok don"t worry about it, just don"t lose that piece of metal that fell out.

I had the battery changed in my watch at a watch repair store. Ever since then my watch won't connect with the time signal and reset itself to the current date and time.

I had a similar problem with my Casio watch when I changed the battery. I put it to one side and used another one and eventually it re-set itself (it took some days I think, although I wasn't watching it too closely.

I suggest a lot of patient waiting!

Battery change for Nixon Kink watch

You have to open your watch caseback. Undo the battery holding contact, get the battery out and memorise the writings on the battery. Buy exactly the same one and replace it in the backwards way you took it out.

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.
