The recently launched UMIDIGI Uwatch GT is the perfect companion for everyday life and sports as it is packed with daily health and fitness resources to help you get the best out of your life.
But what exactly does 5 ATM water resistance mean? And what differentiates water resistance ratings from other types of rating standards, such as the best-known ratings on IP smartphones? We explain better below.
The ingress protection (IP) rating is already common in the mobile industry. For example, the latest iPhone 11 Pro supports IP68, a high level of water and dust protection.
But IP ratings do not take into account water pressure. Therefore, IP ratings are not indicative of the ability of a device to be used during aquatic activities such as swimming. That is why, in the case of watches, the ATM classification is used more.
ATM Ratings – Pressure Water Resistance
The ATM water resistance rating is what you will find in normal watches and probably will find in new wearable gadgets. Pressure tests are measured in ATMs, which represent atmospheres, and are converted to water depth for ease of measurement.
An ATM is equivalent to the static pressure exerted by static submersion in 10 meters of water. The higher the ATM rating, the deeper the product can go unaffected, as the deeper water exerts more pressure. The basic levels of ATM water resistance are described below.
ATM Classification Examples of using water pressure protection
|ATM rating||Water pressure protection||Usage examples|
|1 ATM||Supports pressure equivalent to a depth of 10 meters||Better running and splashing resistance|
|3 ATM||Supports pressure equivalent to a depth of 30 meters||Suitable for daily use. Splash/rain resistant.|
|5 ATM||Supports pressure equivalent to a depth of 50 meters||Suitable for daily use, bathing, low water swimming, snorkeling, water related work, fishing. Splash/rain resistant.|
|10 ATM||Supports pressure equivalent to a depth of 100 meters||Suitable for leisure surfing, swimming, snorkeling, sailing and water sports.|
|20 ATM||Supports pressure equivalent to a depth of 200 meters||Suitable for professional sea activities, surface water sports, and diving.|
With a water resistance rating of 5 ATM, the UMIDIGI Uwatch GT is pressure-resistant to a depth of 50 meters, meaning that the watch is not just rain-resistant, but it can also be used during low water activities such as swimming or snorkeling.
