The Casio Forester FT500WVB watch has an EL (Electroluminescent) backlight and requires one silver oxide button battery. The SR621W battery (also known as type 363) is recommended by the instruction manual for the watch. Note the suffix "W" means this battery is a high drain type which is suitable for powering a watch mechanism and the EL light as well for 2 to 3 years, depending on use of the light. "SW" suffix batteries are low drain and are intended only to power a watch mechanism, and not a light. Note also the "SR" prefix indicates the battery is silver oxide and not lithium. The SR type batteries do not use mercury and are therefore safer to dispose of when they are discharged. I have found the type SR626W (also known as type 377) battery is also suitable for the FT500WVB watch and it has more stored power and should therefore last longer.

Last, the Casio Forrester FT500WC looks exactly like the FT500WVB, but it is a different watch internally. The FT500WC has an LED light and requires two batteries- the SR920SW low drain silver oxide battery which powers the watch mechanism and the CR1616 lithium battery which powers the LED. The LED is brighter than an EL light and stays on longer than the EL light when activated. But the LED has a bright dot light source that some might find annoying.

I haven't worn my fossil watch (FS 4337 model) for some time & decide to wear it & shook it, adjust it, & it dosn't work. Usually when I don't wear it for about 2 weeks, I shake it...

If you have a Fossil FS4337 Chronograph, shaking the watch shouldn't be doing anything other than exercising your muscles; the movement is a battery-driven quartz movement whose movement is controlled only by whether the stem has been pulled out (stopping the movement and saving power) or whether the battery still has enough power to activate the stepping motors that move the watch hands. Based on the symptoms that you've described, I would suggest that it's probably time to change your watch battery.

Often, when a watch battery is running low but isn't completely dead, pulling the stem into time-setting mode will stop the movement and permit the battery to "rest," giving it (briefly) a bit more reserve amperage to put out when you push the stem back in. That's how you can sometimes get a quartz watch to run for a few minutes after the battery appears to be dead. That may also be why your watch has started running again after you've set the time and date.

Fossil analog quartz watches tend to use silver oxide (usually #377 or #379) batteries instead of longer-lasting lithium batteries. In ordinary use, I would expect a silver oxide battery to provide between 1 and 2 years of service before it needs to be replaced. I can't remember if Fossil chronographs (which also use quartz movements) use a silver oxide or lithium battery. Lithium batteries often provide an additional year or two of service in analog watches, compared to silver oxide cells; digital watches using them supposedly may last as long as 10 years with a lithium battery, assuming you don't use the backlight or audible alarm functions. Note, however, that these batteries are different sizes and different voltages, so you can't substitute one for the other.

Finally, none of this advice applies if you have a Fossil watch with a true mechanical movement in it. In that case, gently shaking the watch may spin the winding rotor enough to start the watch back up again. However, an even faster way of winding those watches is to use the winding / time set crown to wind the mainspring directly instead of relying on the geared-down action of the winding rotor. Automatic watches can bind up if they are not used for a period of time; the lubricating oil used in some of the pivots can harden--or at least provide enough resistance that the movement may require more initial force to start running than to continue running. That behavior usually indicates that it's time to have the mechanical movement cleaned and re-lubricated.

I havent worn this watch for about a year the battery has 10 year warranty and was working it has stopped working.

A few watch companies...Bulova being one of them used to give a 10 year warranty but I dont know of any batteries that actually last 10 years! The average life of a 1.5 volt silver oxide battery is 2-3 years (sometimes a smidge longer) depending on the age and condition of the watch. A 3 volt lithium battery will get on average 3-4 years.

Im guessing that your battery is probably dead! :-)

never replace a 1.5 cell with a 3volt, it will damage the movement...and besides, replacing with a higher voltage will not make it last longer or run 'better' only needs 1.5volts to function properly

Luminox 8152 chrono

If you have your instruction manual it should tell you how to reset the chrono. i have the Luminox 8352 and it says to pull the crown out to the 3rd position. then press and hold both the start/stop and lap/reset buttons for a couple of seconds. you'll see the second hand rotate, then you can single click the start/stop button to manually move the second hand 1 second, or you can hold it and it will continue move for a longer period until time desired. if you need to adjust the other chrono hands, click the lap/reset button and then you can click the start/stop button again. repeat for the minute/hour chrono hand. when you're finished push the crown back in. it might work even though it's a different model, worth a shot? hope that helps. these are really great watches.

Resetting the Watch after Changint a Battery

yes! I Don't recommend doing this yourself but if you open up the back you will see AC and a spot to touch with a twezer to short it out to the main plate.Then close the watch and pull the crown out and push the pushers in and out to set each dial.
