Water resistance is tested in measurements of atmosphere (ATM). Each ATM denotes 10 meters of static water-pressure. This is not the depth to which a watch can be worn. Many watch cases will list the basic measurement of 1 ATM as "water-resistant." These watches will withstand small splashes of water but should not be worn while washing the hands or submerging the hands in water. Remember， water resistance is tested under static conditions. Wearing a watch which is 50 metres water resistant in water will expose the watch to a much greater pressure than during a 50 metre static test. Therefore the number of metres shown on the watch does not indicate the depth that the watch can be taken to. Here is a general guide50M = 5ATM = Shower Proof - it's ok to get it wet a bit. 100M = 10ATM = Extended Water Exposure good for swimming or snorkeling. 200M = 20ATM = Pressure Resistant made for Scuba and Skin Diving.Q: A 100M watch is surely strong enough on a shallow dive?! A: No! It isn't because it has not been high pressure sealed. 100M watches are only good for Snorkeling! Q: What will happen if I try to dive with a watch that is less than 200M Resistant? A: The watch's seal will be broken， it will flood and break..irrepairably. Q: So which watch to buy? A: Think about what you need it for and bear in mind that Scuba Watches (200M) look really cool but tend to be very heavy， which makes them uncomfortable for everyday use.<br /><br />  IPXX Rating Chart<br />IP Code   The IP Code (or International Protection Rating， sometimes also interpreted as Ingress Protection Rating*) consists of the letters IP followed by two digits and an optional letter. As defined in international standard IEC 60529， it classifies the degrees of protection provided against the intrusion of solid objects (including body parts like hands and fingers)， dust， accidental contact， and water in electrical enclosures. The standard aims to provide users more detailed information than vague marketing terms such as waterproof.The digits (characteristic numerals) indicate conformity with the conditions summarized in the tables below. For example， an electrical socket rated IP22 is protected against insertion of fingers and will not be damaged or become unsafe during a specified test in which it is exposed to vertically or nearly vertically dripping water. IP22 or 2X are typical minimum requirements for the design of electrical accessories for indoor use.<br /><br />                                                <br />
