I bought the water resist watch from walmart this evening it doesnt have a name brand on the watch but i think its a casio but it didnt come with the instructions on how to use it, the number on the back of the watch is AW60447W and i just need the directions on how to set the time and alarm and how to set the day and how to use the timer.. it only has 4 buttons top left is light, top right start/stop, bottom left mode, bottom right lap/reset and theres a button on the bottom that just says EL

unless it is waterproof you should remove electronics before going near water....
even water proof and water resistant electronics can get hairline fractures that will allow water to seap in.

once wet it will stop working.
BUT - - if you dry it thoroughly and replace batteries (if they also got wet) it can work again but you must be sure all water is dried before returning power to machine

as an example, a CRT tv i owned years ago was submerged in water for a while... of course it no longer worked.
but after three days of having a fan blow air over it it was completely dry and again worked

WARNING: only works for CRT tvs the flat screen tvs likely will allow water to seep into the screen so while you think it is dry it is still wet in the screen

Theoretically means it will resist water penetration to 50 meters. Approx 150 feet deep.
I would not test that limit, but you should be fine in a pool or shower etc..

Read the number of the back of your watch and enter it into the search box

mcdevito 75 here, Usually 50--100 meters of water resistance on brand new watches. However after a battery change, unless you also change the gasket (rubber ring) on the cover, you could loose all water resistance capability.

1 bar = 10 meters (approximately).

So a 20 Bar watch is resistant to 200meters.

"Water resistant 5 bar" means that it is water resistant to and depth of 50 meters. (1 bar is approximately equal to 10 meters of water depth).

My knowledge, yes.  On the back of the watch should say something.
