Often, our customers and watch fans wonder if a certain watch is really "water resistant" and what it can be used for. Wristwatches whose original condition is resistant to water penetration up to the specified depth are referred to as "water resistant". "Water protected", however, means that the watch is resistant to splashing water or everyday (hand) washing. The DIN standard 8310 regulates whether a watch is considered "water resistantt" or not. The criteria are typographic tests. Example: Under normal laboratory conditions, the watch can withstand a pressure that is 200 meters deep. This means to 20 bar or 20 ATM. The watch can be classified as a diver's watch and you can dive with it safely. Watches with 10 ATM, however, should rather be used only for swimming and snorkeling, while watches with 5 ATM are only considered "water-protected", whereby they are protected against splashing water and can be worn while bathing. If a clock is only awarded 3 ATM, you should do without bathing with this clock better. Splashing water should not be a problem.
