If you are looking for a wristwatch to swim or dive with, you must not expect that any water resistant watch is nice for such activities. Actually some water resistant watches can be used for swimming, while others not. With a waterproof wristwatch on your wrist you ought not be afraid of splashes of water, however, you should remove such a watch before taking a shower, because very few wristwatches are really water-resistant.
If you wish to know whether you can swim or dive with your timekeeper, you must be very attentive about its markings. Never swim or dive with a timepiece that features the marking “water-resistant” 3 ATM (30 m)”. Timepieces with resistance to water to 50 m are not designed for diving, however, such timepieces can be worn while swimming or taking a bath. The nicest watches are those with resistance to water to 10ATM (100 m), these are appropriate for diving.
What to fake wristwatches, most of such timepieces are marked as water-resistant, but this does not mean that these timekeepers are designed for diving. If you are going to buy a watch for diving, you have better buy an original timepiece, for example a Rolex watch, but not a Rolex Graphite Cosmograph duplicate timepiece. An imitation Rolex watch is only a copy of an original Rolex wristwatch, but it does not have all the features of the authentic Rolex timepieces. You must be aware that you will not be able to turn your wristwatch for refund for refund, if the watch was damaged by water, no matter if it is a genuine wristwatch or if it is from a catalogue of imitation wristwatches.
