looking for the owners manual to the casio edific EFR-513sp watch

Try winding it by hand. If it will wind manually and works then the problem is the 'winding mechanism' If it won't wind by hand then you need a watchmaker. Find one that is certified if possible, they are the most schooled.

This is called spring bar or spring pin. You can buy these on ebay. Make sure you get the right size. The distance between watch lugs is the right size. Measurement must be taken in mm.

mcdevito75 here, If you try to wind your watch listen for the distinctive click, click as you wind, if you haer this click, click then it"s a a windup, if the stem just turns without the distinctive sound click, click. then it"s a battery watch, also look for any word on the watch that says Quartz. ONE more thing, you may have a screw down cover on the winding stem, un screw the cover on the stem to get to (the crown, winding stem itself) Most likely you have to un-screw this cover on the stem to get to the actuall stem itself, Invicta makes watches like this to add waterproofing to the watch.

Only if the water resistance is 100m or more.

If your watch has a "no water" icon, then it should not be allow to get wet.

no problem, but charger should be common

Self winding watched should not need to be wound as long as they are being worn.

To tell if the self winding mechanism is working, hold the watch close to your ear (hold it vertical, as though it was on your wrist) and rock it gently. You should be able to hear a ratchet operating (a soft clicking noise).

I can't help thinking your suspicion about the mechanism having failed, sound very likely.

the rotolog actually has 3 batteries in it, 2 being for the led and one for the actual watch mechanism. mine had the same problem but as soon as i had replaced the watch battery it was good to go.
