Watch Water Resistance Explained
Water resistance (also known as "ATM rating") is one of the most important aspects to consider when buying a watch. Watches are equipped with a water protection mechanism to prevent water from reaching delicate parts of the watch's body. The level of water resistance will vary from one watch to the next, but there is some standardization. The ATM water resistance unit is used to measure such ratings. ATM is an acronym for "atmospheres." One ATM unit represents atmospheric pressure at sea level. People often misunderstand these "ATM" numbers and purchase watches that are not water-resistant.
