A great number of people think that a waterproof wristwatchis intended for swimming or diving. You must know that there are watches of various resistance to water: while some of them can withstand deep contact with water, other watches break down after a few minutes after being in water. With a water resistant wristwatch on your wrist you ought not worry if it contacts with water, however, you should remove such a timepiece before swimming, because very few wristwatches are really water resistant.
Before getting a water resistant wristwatch you ought to find out what the markings on the watch mean. The marking “water resistant” or “waterproof” 3 ATM (30 m) means that your timepiece will withstand contact with water, but you cannot swim with such a watch. The marking “water-resistant” to 5ATM (50 m)” means that you can swim with this timepiece on your wrist, but the timepiece is not intended for diving. The greatest wristwatches are those with water resistance to 10ATM (100 m), such watches are appropriate for diving.
Also lots of customers suppose that imitation wristwatches are highly waterproof, but this is a big mistake. If you are going to buy a wristwatch for diving, you ought to choose a genuine watch, for example a Rolex watch, but not a Rolex fakewatch. You must know that an imitation Rolex timepiece imitates an authentic Rolex timepiece greatly, but it is not so fine. You must realize, that both imitation wristwatches and genuine wristwatches will not be accepted for refund if being damaged by water.
