It is not recommended to wear your water resistant watch in a hot shower, sauna or hot tub. The extreme heat causes the metal parts to expand at a different rate than the rubber gaskets. This creates small openings that can allow water droplets to penetrate the watch. Sudden temperature changes are especially harsh. Take care not to jump into a cold pool after wearing your watch in the hot tub. After swimming or diving in salt water, immediately rinse the watch in a stream of fresh water. If your watch has a rotating bezel, turn the bezel several times while rinsing it. This will prevent salt buildup and corrosion of the bezel ring. Leather straps can be made to be water resistant too. Generally however, leather straps are more easily damaged by frequent exposure to water. So if you are going to wear your watch while swimming -- think of buying one with a metal bracelet or a rubber or nylon diver strap. Watch is a precise instrument, even though it has been taken closed measures, which can protect from sweat and harmful gas, but it doesn't mean that you can go swimming with a waterproof watch. Moreover, a watch will appear several unavoidable situations, for instance, glasses can be affected by temperature so that there is a gap between glasses and cover; waterproof aprons will be corroded and oxidized. This entire phenomenon probably weakens its water resistant quality. In conclusion, a water resistant watch cannot be worn when swimming.
