br br HOW WATER RESISTANT IS YOUR WATCH? br Most watches use the measure ATM (or atmosphere) that specifies how many meters or feet the watch can be submerged without being damaged. An ATM is equal to 10 meters. It can also sometimes be referred to as BAR, most commonly used in Europe. br Here’s a guide to how much water your watch can handle: br Water resistant : if your watch does not mention the ATM, don’t get it wet. br 3 ATM (30 meters / 100 feet) : Everyday use such as washing hands or rain. No showering or swimming. br 5 ATM (50 meters / 165 feet) : Brief periods of showering and swimming. No diving or snorkeling. br 10 ATM (100 meters / 330 feet) : Safe for swimming and snorkeling. br 20 ATM (200 meters / 660 feet) : Safe for high-impact water sports such as jet-skiing, and recreational diving. br Diver (250-300 meters / 660-1000 feet) : Suitable for scuba diving. br
