When buying a new water resistant watch you have to understand the instructions and the numbers written on your watch to make sure not to misuse your new watch. Water resistant watches are not all the same as there is differences in durability and the depth of water that it can handle. All water resistant watches have number in bars or atmospheres (units) engraved on the back side of the watch to indicate how much depth it can resist. Some watches have the sentence ‘water resistant’ written somewhere without indicating how much depth it can resist, these kind of watches can resist splashes of water only (weak water resistant watches). If you can’t find anything written on your watch to indicate water resistance then your water is not water resistant at all and it can stop working from body sweat.
